`IMPORTANT RULES FOR SAFE OPERATION
`
`Note to the Installer
`
`Note to CATV System Installer
`This reminder is provided to call the CATV
`system installer’s attention to Article 820-40
`of the NEC (Section 54, Part I of the Canadian
`Electrical Code), that provides guidelines for
`proper grounding and, in particular,
`specifies that the CATV cable ground shall
`be connected to the grounding system of
`the building, as close to the point of cable
`entry as practical.

`

`

`IMPORTANT RULES FOR SAFE OPERATION, continued
`
` Grounding
`
`This equipment has a two-prong plug. Properly ground
`(earth) this equipment by inserting the plug into a
`grounded electrical, two-socket outlet. If this plug is
`polarized it has one wide prong and one narrow prong.
`This plug fits only one way.
`
` CAUTION:
`To prevent electric shock, match wide blade of
`plug to wide slot, fully insert.
`
`If you are unable to insert this plug fully into the outlet,
`contact an electrician to replace your obsolete outlet.
`
`Damage that Requires Service
`For damage that requires service, unplug this equipment
`from the electrical outlet. Refer service to qualified
`service personnel when any of the following occurs:
`(cid:129) There is damage to the power cord or plug

`About This Guide
`
`Introducing the Explorer 2100 and 3100 DHCTs
`
`The Explorer® 2100 and 3100 Digital Home
`Communications Terminals (DHCTs) are
`converters that can view analog and digital
`signals. The Explorer 2100 and 3100 DHCTs
`provide exceptional picture quality and an
`Interactive Program Guide (IPG)–an interactive,
`on-screen browsing and program-selecting menu.
`This guide provides diagrams of the front and
`back panels of the DHCT, diagrams for connecting
`the DHCT to other electronic devices, basic
`instructions for using the DHCT, and
`troubleshooting tips for proper operation.
`Joining the Explorer Club
`Scientific-Atlanta invites you to join the Explorer
`Club. This online club provides news and “what’s
`up” information about the Explorer DHCT and
`offers you a chance to win prizes and other
`premium items.
`You can access the Explorer Club by logging on to
`the Internet and entering our address

`

`Installation Tips
`
`Follow these tips for proper DHCT operation:
`(cid:129) Do not plug the DHCT into a wall outlet that is
`controlled by a wall switch. The IPG data does
`not update when the outlet is switched to the off
`position.
`(cid:129) You can plug your TV into the AC Switched
`Outlet on the back of the DHCT.
`(cid:129) To ensure proper ventilation, do not place any
`objects on top of the DHCT, including devices
`such as your TV.
`(cid:129) If your TV is equipped with a picture-in-picture
`(PIP) feature, see the connection diagram on
`page 13.
`
`Getting Started
`
`Installation Overview
`The following list provides an overview of the
`installation process.
`1. Determine the electronic devices you must
`connect using the information on page 9.
`2. Connect the DHCT and your electronic devices
`using the diagrams in this guide, based upon
`the information on page 9.
`3. Plug in the DHCT to an AC power source, but
`do not press the Power key on the DHCT.
`4. Set the input channel (3 or 4) on your TV and
`VCR.
`5. Wait for the time to display on the front-panel
`display. Then, press the Power on the DHCT.
`See page 28 for detailed instructions.
`6. Program your remote control to operate your
`TV and VCR. (See your remote control user’s
`guide.)

`
`Using an RF Bypass Module
`
`When you use the Bypass feature, the regular
`(analog) cable signal bypasses the Explorer DHCT
`and goes directly to your TV, which allows you to
`view any regular cable program. At the same
`time, the DHCT sends cable signals to your VCR,
`and you can record any channel to which the
`DHCT is tuned, including premium or pay-per-
`view channels.
`When you disable the Bypass feature, both your
`VCR and TV can receive cable signals from the
`Explorer DHCT.
`Note: After installing the Bypass module, tune
`the VCR input to the Explorer DHCT’s output
`channel (channel 3 or 4).
`
`Connecting the Module
`
`Follow these steps to connect an RF Bypass module to
`the DHCT.
`
`CAUTION: Unplug the AC power cord and
`disconnect all cables attached to the DHCT.
`
`1 Unplug AC power cord.
`
`2 Bend the metal tab labeled
`BYPASS toward you.
`Important: Pull off the tab
`and dispose of safely.
`

`power outlet.
`
`Activating and Deactivating RF Bypass
`If your remote control includes a Bypass key, follow these
`instructions to use the Bypass feature.
`To activate the Bypass feature, press the Bypass
`key. The Bypass indicator illuminates on the DHCT.
`Notes:
`(cid:129) You can only view analog channels; digital channels are
`not available while the Bypass feature is active. (Verify
`with your cable service provider which channels are
`analog and which channels are digital.)
`(cid:129) Use the Bypass key to toggle the feature on and off.
`To deactivate the Bypass feature:
`1. Press the Bypass key on the remote control. The Bypass
`indicator no longer illuminates on the Explorer DHCT.
`2. Tune your TV using one of the following methods:
` (cid:129) If the TV/VCR switch on your VCR is in the VCR
`position, you must tune your TV to the VCR output
`channel (channel 3 or 4). You can view a tape, or you can
`view the channel to which the Explorer DHCT is tuned.
` (cid:129) If the TV/VCR switch on your VCR is in the TV position,
`you must tune your TV to the Explorer DHCT’s output
`channel (channel 3 or 4). You can only view programs
`from the Explorer DHCT, regardless of what your VCR is
`playing.

`Connecting the DHCT
`
`After you connect the DHCT and any additional
`electronic devices in your system, follow these
`steps:
`1. Verify that the DHCT is connected to the 75 Ω
`coaxial cable coming from the wall.
`2. Plug the DHCT and other devices into your AC
`power source.
`Important: Do not press the Power key on the
`DHCT.
`3. Turn on the power to your TV and VCR, and
`tune your TV and VCR to the input channel
`assigned by your cable service provider (channel
`3 or 4).
`4. Wait for the time to display on the LED.
`5. Press the Power key on the DHCT.
`6. Program your remote control to operate your TV
`and VCR. (For inst
