`

`
`4. COMMUNICATOR Registration
`Prior to operation of the Wireless 6000 system, each Communicator must be registered for
`use with a specific base station. The base station will then recognize all registered
`Communicators when their power is on, differentiating between them and interfering
`transmissions from other electronic equipment operating on similar frequencies.
`
`Register each Communicator as follows:
`
`Be certain all Communicators to be registered are powered off and the base station
`power is on.
`
`Open the base station and press the registration button near the lower-left corner of the
`base station circuit board shown in Figure 5.
` If no Communicators are powered on, the status light shown in Figure 5 will be blinking
`red. If any Communicators are powered on, the status light will be blinking green.
` After you press the registration button, the Communicator ID display will show a
`small (cid:178)o(cid:179) for open.
`
`Press and hold the B button while pressing and releasing the PWR (power) button to
`turn the Communicator on, then release the B button. This will cause the Communicator
`to enter the registration mode.
` The status light in the base station will be blinking green, and the Communicator ID
`display will continue to show a small (cid:178)o(cid:179) for open.
` The power lights next to the A1 and A2 buttons on the Communicator will be
`blinking red then will change to green.
`When the registration is successfully completed:
`
` The green status light in the base station will be on steady and the Communicator
`ID display, to the left of the status light, will show the ID number assigned to this
`Communicator. ID numbers are assigned sequentially as 0 thru 9, A, b, C, d and E.
`
` One of the power lights on the Communicator will remain on steady green.

`
`TO CHANGE BATTERIES: When a battery is becoming weak, a voice in the earpiece
`will say (cid:178)Change battery.(cid:179) When this happens, take the Communicator out of its pouch
`and remove its battery by carefully sliding the battery-release latch in the direction of
`the arrow shown in Figure 6. Pull up on the end of the battery near the battery-release
`latch and lift the battery out of the Communicator, or turn the Communicator over and
`catch the battery in your hand.
`
`TO REPLACE BATTERIES: When replacing a battery in the Communicator, place the
`end of the battery with the metal contacts into the battery holder on the Communicator,
`in the same position as the battery you removed. Press the top of the battery carefully
`into the battery holder until it snaps in place under the battery-release latch.

`
`Plug the adapter into an AC electrical outlet and secure it to the outlet with the
`grounding screw (if provided). The red lights will come on and go off, then the yellow
`lights will come on and stay on.
`2. 230 Volt AC Adapter Connections Outside the U.S.A.
`Connect an electrical plug to the wires on the power cable according to color
`codes (Brown = live, Blue = neutral, Green with yellow stripes = ground).
`
`Plug the other end of the power cable into the receptacle on the AC adapter.
`
`Remove the spade lugs from the brown and blue wires of the battery charger
`cable and cut the green/yellow wire as short as possible. No ground wire will be
`used. Cut the connector off the AC adapter output cable. Strip enough of the
`insulation from the wires of both cables so they can be spliced. Splice the wires
`from the AC adapter cable to the (cid:178)AC(cid:179) wires of the battery charger cable. Cover
`the splice with electrical tape or shrink tubing.
`
`Plug the electrical plug into an AC electrical outlet.

`Insert battery in one of four charging ports until it clicks in place.
`Battery charging time is approximately 2 hours.
`Yellow light next to each battery port stays on while port is empty.
`When battery is in port, yellow light flashing next to battery port indicates
`CHARGE PENDING, which means the temperature where the charger is
`located is out of the battery(cid:181)s operating range (32o-104oF, 0o-40oC).
`Adjust the room temperature or move the charger to a cooler area.
`When battery is in port, yellow light on steady next to battery port means
`CHARGE FAILED. Follow diagnostic instructions on side of battery charger.
`Red CHARGING light next to battery port stays on while battery is charging.
`Green READY light next to battery port goes on when battery is fully charged.
`Store fully charged batteries in storage ports.
`

`
`SECTION 2. SYSTEM INSTALLATION AND SETUP
`
`2.1
`
`INTERFERENCE PREVENTION
`CAUTION: Interference may occur if the audio system is not properly installed.
`
`The following types of interference could occur if precautions are not taken in installation of
`the system. Read this section carefully before proceeding with the installation.
`2.1.1 Radio Frequency (RF) Interference
`Resolving the cause of RF interference is difficult and time-consuming. The following
`precautions will help avoid the most common RF interference problems.
`
`Find the best base station/antenna location before mounting it permanently.
`
`Solder all joints (including crimp joints) at the speaker location. This is especially
`important in damp climates
`
`Be certain all joints and connections are tight.
`
`Avoid leaving long lengths of unshielded wire anywhere in the audio system.
`
`Ground the shield of the outgoing speaker cable. In severe cases of interference,
`grounding the shield at the speaker may help.
`
`AM broadcast and FM radio frequency interference may cause similar problems but require
`different corrective action. AM interference symptoms may appear to be less severe at
`certain times of day, since a 50% reduction of transmitter output power at dusk (5-7 PM) is
`required in some areas for AM radio stations rated at or above 100kW. Note the following
`symptoms carefully to determine the possible cause of interference. Call HME at
`1-800-848-4468 if assistance is required.
`
`AM Interference:
`
`Static or hum may be heard in the headset when the system is active. The point of entry of
`the AM interference is at the outside speaker/microphone via the cables connected to the
`base station. In order to block out the AM signal, first locate and identify any AM station in
`the area, and find out its operating frequency and transmitter output power. The system can
`then be modified with a network of inductors and capacitors that will trap the undesirable
`AM signal at the point of entry into the system. Static, hum and/or voice may be heard in the
`headset when the system is active or when transmitting in either channel A or B. The point
`of entry for the interference can be at three different locations: the outside speaker cables,
`the COMMUNICATOR® receiver, and the base station transmitter. The AM station frequency
`may completely suppress or overpower the audio system(cid:181)s transmitter signal, depending on
`the operating frequency, transmitter tower location and output power of the AM radio station.
`It may be necessary to move the base station.
`
`FM Interference:
`
`A common symptom of FM interference is the presence of cracks, pops and other noises in
`the Communicator when transmitting on either channel A or B, or when the system is active.
`
`2400MHz Wireless Telephone Interference:
`
`If there is a 2400MHz cordless telephone nearby, interference may occur. However, because
`the Wireless 6000 is a frequency-hopping system, this problem is unlikely. If it does occur,
`changing frequencies on the telephone may alleviate the problem. If not, move the phone as
`far as practical from the base station, or ask the customer to use another type phone.
`
`9
`
`APP2869
`
`

`
`2.1.2 Electrical Interference
`The effect of electrical faults in appliances and other electrical equipment can make operation
`of a wireless system ineffective in communicating with customers. The most common
`symptoms are static, hum, crackling, buzzing and zip sounds in the headset when the system
`is active. Interference caused by electrical faults in lighting systems might not be noticed
`immediately, since most lighting systems are controlled by a timer or light-sensing device.
`Faulty Wiring or Components:
`
`Faulty components or electrical wiring in menu boards or speaker posts can cause symptoms
`identical to those caused by AM interference. Remove power to the menu board or speaker
`post at the circuit breaker until proper repair of the electrical system can be made.
`
`Improper Earth Grounds:
`
`Improper earth grounds throughout the building can result in random buzzing and zips in
`the headset when operating in either channel A or B. Placing a surge protector between the
`base station AC adapter and the AC electrical outlet will eliminate the problem in most cases.
`
`2.2
`
`PREPARATION FOR INSTALLATION
`
`IMPORTANT: If you haven(cid:181)t already done so, before proceeding with the installation,
`plug the battery charger into an AC electrical outlet and place all COMMUNICATOR®
`batteries into it for charging while the other equipment is being installed.
`
`Approximately 3 hours is required for installation of the Wireless 6000.
`
`Before installing the system, coordinate the time of installation with the store owner/manager
`to minimize disruption of business.
`
`Be certain the site has been properly prepared as follows.
`
`Electrical power must be connected and available.
`
`Some type of compatible vehicle detector loop or other vehicle detector system must
`already have been installed in the drive-thru lane(s).
`2.2.1 Tools Required
`Phillips (cross-point) screwdriver, size #2
`
`standard (slotted) screwdriver, 1/8 inch (4 mm)
`
`power drill and drill-bit set
`
`fish tape, 100 feet (30 meters)

`

`
`INSTALLATION PROCEDURE
`2.3
`2.3.1 Base Station Installation
`Discuss the location of the base station with the store owner or manager. It should be
`mounted with the bottom of the cabinet no more than 5 feet (1.52 meters) above the floor,
`away from grease and large metal objects. It must be near enough to an available AC
`electrical outlet to reach the outlet with the 10 foot (3 meter) AC power adapter cord. It
`must be near enough to the pull box to be reached by the cables, which will be pulled into
`the building through the outer wall. Also, the antenna(s) used for the base transmitter must be
`installed to provide a separation distance of at least 7.87 inches (20 cm) from all persons, and
`must not be co-located or operating in conjunction with any other antenna or transmitter.
`
`NOTE: For dual drive-thru installations, follow the instructions below to install two base
`stations near each other. The two base stations must not be mounted closer than 3 feet
`(.91 meter) from each other. Interconnect the J22 and J26 connectors as shown on pages
`25 (cid:176) 28. Cable pulling and installation of an outside speaker and microphone for each lane
`will also be done according to the following instructions.
`Walk test transmission and reception with two people using COMMUNICATOR®s (with fully
`charged batteries), pressing button B to communicate with each other around the area
`where the Communicators will be used. Also, walk past the menu board to test reception
`when using speed-team operation. Continue doing this with the base station in various
`locations until the best possible transmission/ reception is found. When you have determined
`the best location, unplug the AC adapter and mount the base station on the wall as follows.
`
`Hold the base station, with its door open, against
`the wall at the desired mounting location, and
`mark the wall through the four screw holes on
`the back of the cabinet as shown in Figure 10.
`
`Remove the base station from the wall and drill
`four 3/16 inch (4.76mm) holes in the wall at the
`marked spots.
`
`Insert the enclosed #6 screw anchors into
`the holes.
`
`Screw the four enclosed screws into the anchors
`as shown in Figure 11, leaving the screw heads
`approximately 1/8 inch (3.18mm) away from the wall.
`Position the four screw holes in the back of the
`base station over the four screws, and slide the
`base station downward to secure it in place.
`
`Connect the base station power adapter cable to
`the base station(cid:181)s 16.5VAC adapter as you did for the
`battery charger, as shown in Figure 7, page 7. For
`use outside the United States, see 230VAC adapter
`connections shown in Figure 8, page 7.
`
`Connect the two wires at the other end of the
`cable to J16 on the top-left of the audio circuit
`board in the base station. Plug the adapter into
`the electrical outlet nearest the desired base
`station mounting location.

`2.3.2 Cable Pulling
`CAUTION: If not using the HME Audio Cable, be certain the speaker/microphone wires
`are a twisted pair. For full-duplex installations, the speakers and microphones must
`use separate cables or audio feedback will occur.
`Never run high-voltage cables in the same conduit with audio or loop cables.
`
`The recommended HME cable contains four color-coded, insulated wires and a bare
`shield (drain) wire. This cable can be used to connect any Wireless 6000 component to
`the base station.
`
`Pull the cables (two for full-duplex, one for half-duplex) through the underground conduit
`from the outside speaker post or menu board into the building as follows.
`
`NOTE: For dual drive-thru installations, repeat the following steps to route cable from
`inside the building to the speaker post or menu board in each drive-thru lane.
`
`
`
`Run fish tape from inside the building, through the conduit to the speaker post or menu
`board.
`
`Go outside. If more than one cable are being pulled, mark the cables and spools for
`identification. Fasten each cable to the fish tape where it comes out of the conduit,
`and return to the customer-service area inside the building.
`
`Pull the fish tape and cable through the conduit, into the building. As the cable comes
`through the conduit, disconnect it from the fish tape and continue pulling enough of it
`through the conduit to reach the base station.
`
`Return to the outside customer-service area, and route the cable from the outside
`conduit to the speaker and microphone units in the speaker post or menu board.
`
`Cut the cable, leaving approximately 3 feet (915 mm) of slack. If more than one cable
`have been pulled, mark the ends of the cables again for identification.
`
`Remove approximately 2 inches (50 mm) of the outer insulation from the end of each
`cable. Strip approximately ½ inch (12 mm) of insulation from each of the four wires in
`the cable.
`
`When all cables have been pulled from outside into the building, gather the cables
`inside the building and route them together to the base station, through walls and over
`ceiling panels if possible.

`
`2.3.3 Outside Speaker and Microphone Installation
`and Cable Connections
`This section describes standard, full-duplex installations, using the standard microphone
`and the SP2500LP Low-Profile Speaker. Specific installation requirements may vary.
`Refer to the wiring diagrams on pages 25 (cid:176) 28 for cable connections.
`
`Although the standard microphone and SP2500LP will provide optimum performance, in
`some cases the DM1 Microphone may be used. For DM1 installation instructions, see
`Appendix E.
`
`NOTE: For half-duplex installations, see Appendix D for installation of the SP2000A
`Speaker/Microphone Unit. The SP2000A is used as the speaker and microphone in
`half-duplex installations.
`
`In order to avoid audio feedback, the speaker unit must be mounted at least 2 feet (610 mm)
`from the microphone unit. Positioning of the two units is critical.
`
`The microphone unit must be mounted inside the speaker post or menu board, against the
`s
