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.

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.

CAUTION

RISK OF ELECTRIC SHOCK

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-per­view 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).

14

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.

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

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:

• You can only view analog channels; digital channels are
not available while the Bypass feature is active.

• 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:

• 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 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 W
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 and select channels 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 user’s guides that your cable service
provider included with the DHCT installation
package. These guides provide operating
instructions for using the IPG, your remote
control, and the VCR Commander module (if
available).

Tips for Improved Performance

Check and Correct

If your DHCT does not perform as expected,
the following tips may help. If you need further
assistance, contact your cable service provider.

No picture

• Plug your TV and DHCT into an electrical
outlet that is not controlled by a wall switch.

• Verify that all cables are properly connected.

• Verify that the power to your TV is turned on.

• If your system includes a VCR and/or stereo,
verify that you have properly connected them
to the DHCT.

• Verify that your TV is tuned to the proper
output channel (3 or 4).

• Verify that the Bypass feature is disabled. See
Using an RF Bypass Module for more
information.

Distorted picture

• Verify that all cables are properly connected.

• Adjust the TV to channel 3 or 4.

No sound

• Properly plug your TV and DHCT into an

electrical outlet.

• Verify that all cables are properly connected.

• Verify that the power to your TV is on.

• If your setup includes a VCR and/or stereo,
verify that you have properly connected them
to the DHCT.

• Verify that your TV is tuned to the proper
output channel (3 or 4).

• Verify that the volume is turned up.

• Verify that the Bypass feature is disabled. See
Using an RF Bypass Module for more
information.

Tips for Improved Performance, continued

DHCT does not work

• Verify that the DHCT is properly plugged into
an electrical outlet that is not controlled by a
wall switch.
