IMPORTANT RULES FOR SAFE OPERATION

Note to System Installer
(U.S.A. and Canada Only)

WARNING
TO PREVENT FIRE OR ELECTRIC SHOCK, DO NOT
EXPOSE THIS UNIT TO RAIN OR MOISTURE.

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.

This symbol is intended to alert you that uninsulated
voltage within this product may have sufficient
magnitude to cause electric shock. Therefore, it is
dangerous to make any kind of contact with any
inside part of this product.

This symbol is intended to alert you of the presence of
important operating and maintenance (servicing)
instructions in the literature accompanying this product.

CAUTION: To reduce the risk of electric shock, do not
remove cover (or back). No user-serviceable parts inside.
Refer servicing to qualified service personnel.

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 program­selecting 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.

8

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.)

7. Use the IPG to browse and view your program
preferences. (See the IPG user’s guide.)

Getting Started

Installation Tips

Follow these tips for proper DHCT operation:

• 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 o
position.

• You can plug your TV into the AC Switched Outlet
on the back of the DHCT.

• To ensure proper ventilation, do not place any
objects on top of the DHCT, including devices such
as your TV.

• If your TV is equipped with a picture-in-picture (PIP)
feature, see the connection diagram on page 13.

Optional Devices

Connecting a VHF Transformer for
Non-Cable-Ready TV

If your TV is not cable ready, follow these steps to
connect a VHF transformer.

After you connect the transformer, your TV is
considered “cable ready” and you can connect
additional electronic devices to your TV and the DHCT.

Continue with connecting your TV to the DHCT and
any other devices in system.

Connecting a VCR Commander Module

The VCR Commander Module is a
device consisting of an infrared (IR)
transmitter and cable that allows
you to use the IPG (on-screen
menu) for selecting the programs
you want to record. You do not
have to set your VCR separately.
Your VCR automatically begins
recording the program you selected
at the set time and channel.

After connecting the VCR Commander Module to
your DHCT, place the IR transmitter in one of the four
locations shown in the following diagram.

Do not use

Connect to CABLE OUT on
DHCT or to OUT TO TV on VCR

Connect VHF transformer

Connect VHF antenna terminals
on TV

Contact your cable service provider for additional
information about the VCR Commander Module.

CAUTION: Unplug the AC power cord and

disconnect all cables attached to the DHCT.

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.

1 Unplug AC power cord.
2 Bend the metal tab

labeled BYPASS toward
you.
Important: Pull o the
tab and dispose of safely.

3 With the Bypass module

labels facing up and
toward you, insert the
multicable connector
into the DHCT.

4 Insert the CABLE IN

connector on the Bypass
module into the CABLE IN connector on the DHCT.

Note: Fold the multicable connector into the inside

of the Bypass module.

• If no, plug in the power cord to an AC
power outlet.

Optional Devices, continued

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:

• 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.)

• Use the Bypass key to toggle the feature on and o .
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:

• 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.

• 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.

Using the DHCT

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 instructions see your remote control
user’s guide.)

Operating the DHCT

Choose one of the following options to operate the
DHCT:

• Press the Power key on the front panel of the
DHCT.

• Use your remote control keys. (Refer to your remote
control user’s guide for instructions on which key or
combination of keys to press.)

Control the volume, select channels, select on-screen
functions, and change settings using the keys on the
front panel of the DHCT or the remote control keys.

Using the IPG, Remote Control, and
VCR Commander Module

Read the users’ guides that your cable service
provider included with the DHCT installation package.
These guides provide the set-up and operating
instructions for the IPG (on-screen menu), your
remote control, and the VCR Commander Module (if
available).
