`
`
`FCC LICENSING
`The HME PRO850 is Type Accepted under Part 74 of the United States Federal Communications
`Commission (FCC) Code of Federal Regulations governing general purpose applications. The system
`requires an FCC station license if operated within the United States or its possessions. Licensing of this
`equipment is the User(cid:182)s responsibility. Licensability depends on the User(cid:182)s classification, equipment
`application and frequency selected. The user should contact the appropriate telecommunications authority
`for any desired clarification.
`CAUTION: Changes or modifications made by the user could void the user(cid:182)s authority to operate
`PRO850 equipment.
`
`MANDATORY SAFETY INSTRUCTIONS
`TO INSTALLERS AND USERS
`Use only manufacturer or dealer supplied antennas.
`Base Station Antenna minimum safe distance: 9.54 inches (24.24 cm) at 100% duty cycle.
`Base Station Antenna gain: zero dBi referenced to a monopole.
`The Federal Communications Commission has adopted a safety standard for human exposure to RF
`(Radio Frequency) energy, which is below the OSHA (Occupational Safety and Health Act) limits.
`Antenna mounting: The antenna supplied by the manufacturer or radio dealer must not be mounted at a
`location such that during radio transmission, any person or persons can come closer than the above
`indicated minimum safe distance to the antenna, i.e. 9.54 inches (24.24 cm) at 100% duty cycle.
`To comply with current FCC RF exposure limits, the antenna must be installed at or exceeding the
`minimum safe distance shown above, and in accordance with the requirements of the antenna
`manufacturer or supplier.
`Antenna substitution: Do not substitute any antenna for the one supplied or recommended by the
`manufacturer or radio dealer. You may be exposing person or persons to excess radio frequency
`radiation. You may contact your radio dealer or the manufacturer for further instructions.
`WARNING: Maintain a separation distance from the base station transmit antenna to a person(s) of at
`least 9.54 inches (24.24 cm) at 100% duty cycle.
`You, as the qualified end-user of this radio device must control the exposure conditions of bystanders to
`ensure the minimum separation distance (above) is maintained between the antenna and nearby persons
`for satisfying RF exposure compliance. The operation of this transmitter must satisfy the requirements of
`Occupational/Controlled Exposure Environment, for work-related use. Transmit only when person(s) are
`at least the minimum distance from the properly installed, externally mounted antenna.

`
`SECTION 1. INTRODUCTION
`
`
`PRO850 equipment operates in the UHF band from 470 MHz to 740 Hz in 18 MHz subsets. Transmitters and
`receivers operate in different, non-adjacent 18 MHz bands. Synthesized frequencies can be selected in 25 kHz
`increments over each 18 MHz band, for 720 transmit and 720 different receive frequencies.
`Base stations can be configured with up to four receivers and two transmitters, supporting up to four Beltpacs in full-
`time transmit, full-duplex operation. Two or three base stations interconnected can support up to twelve beltpacs
`operating at once. The channel lockout feature supports several beltpacs sharing the same frequency. In this mode,
`one beltpac user on a shared frequency can transmit at a time. If another user is already transmitting on that frequency,
`a (cid:179)busy(cid:180) signal will be heard. A maximum of sixteen beltpacs can be used with a system (one to three base stations).
`A feature can be selected that scans through all available intermodulation-free frequency groups to automatically
`configure the system for the best available set of frequencies. Specified frequencies can be saved for quick recall.
`The PRO850 can be configured for fixed power output levels or automated output power control. With the
`automated feature selected, the PRO850 senses how far a beltpac is from the base station and automatically
`determines at what power level the beltpac should be operating, eliminating base station receiver overload and
`increasing beltpac battery life.
`Two hardwired intercom channels provide simultaneous 2-wire and 4-wire operation.
`The base station headset interface automatically detects and accommodates dynamic or electret microphones.
`It provides direct access to intercom channels 1 and 2, beltpacs only or all channels.
`Any beltpac button can be configured to activate the base paging relay and, at the same time, audio is routed to the
`paging output.
`The base can be configured to initiate an alert for various conditions, including low battery condition or button
`press from a beltpac.
`The PRO850 is fully compatible with RTS® and ClearCom® hard-wired intercom systems.
`With the provided PC850 software, the base station and beltpacs can be configured on a PC, and configuration
`settings can be saved to files. An RS-232 serial port and a USB port on the rear panel of the base station provide
`PC interface capability. Beltpacs can also be configured using a Palm-OS PDA with the optional PDA850 software.
`The base station can operate from a standard 12-14VDC power source or from an external DC source such as a
`vehicle electrical system for mobile operation.

`connection to devices other than a headset.
`In the 2-Wire mode;
` If you have an RTS system, only one 2-wire cable
`is needed for connecting bases. The switch on the
`back panel of the base station must be set for RTS
`TW. One cable carries both CH1 and CH2.
` If you have a ClearCom system, two cables are
`needed for connecting base stations. The switch on
`the back panel of the base station must be set for
`CLEAR-COM.
`In all multibase configurations, connect the Aux Out
`from Slave 1 to the Aux In of the Master Base Station
`and connect the Aux Out from Slave 2 (if present) to

`
`1. Power Switch
`Press the upper part of the switch to turn the power on. A red light on the switch will be lit when the base
`station power is on. Press the lower part of the switch to turn the power off. The red light will go off.
`2. Beltpac Configuration Connector
`After beltpac configuration settings have been made in the base station, plug one end of the enclosed RJ10
`interconnect cable into this connector, and plug the other end into the RMT receptacle on the bottom of a
`beltpac to upload the settings into the beltpac. Repeat this to upload settings for each beltpac to be used.
`CAUTION: Be sure not to turn the beltpac power off and on again while it is connected to the base
`station. If this does happen, unplug the cable and cycle the beltpac power again.
`3. Wired Status Indicator Lights
`CH1 and CH2 lights:
`If a 4-wire intercom channel is enabled, the respective CH1/CH2 light will blink when the PRO850 is
`sending audio on that intercom line.
`If a 2-wire interface channel is enabled, the respective CH1/CH2 light will be on steady when the user
`is not talking. When the user is talking, the light will be on steady and blinking off.
`AUX light:
`The auxiliary light indicates use of the ISO+ mode. When ISO+ is on, the AUX light will be on
`steady. When someone is talking on the ISO channel, the light will be on steady and blinking off.
`4. Receiver Status Indicators and Buttons
`RECEIVER STATUS lights 1 (cid:177) 4:
`Steady red if the respective receiver squelch is turned down, or if it is receiving a signal (squelch is open).
`Blinking amber when the respective receiver is receiving status update from a beltpac.
`
`Steady green when the beltpac user is talking through the receiver.
`
`Blinking red or green if the beltpac being received has a low battery condition.
`
`RECEIVER QUICK MENU buttons 1 (cid:177) 4:
`When pressed, squelch and audio controls for the respective receiver are provided immediately on the
