Access Cable Services and Programs
You can access your cable services using the
remote control or the keys on the front panel of
the DHCT. (Refer to your remote control user’s
guide for programming instructions.)
• Press the Guide key to access the on-screen
guide. The on-screen guide displays schedules
of TV programs and other services available
from your cable service provider, such as
video-on-demand and pay-per-view
programs.
• Use the arrow keys to highlight a program in
the schedule.
• Press the Info key for a description of a
specific program (either from the on-screen
guide or while viewing a program).
• Press the Select key to view a specific
program in the guide.
For more information, read the user’s guides
that your cable service provider included with
the DHCT installation package. These guides
provide operating instructions for the on-screen
guide, your remote control, and the VCR
Commander™ service (if available).
Check and Correct
If your DHCT does not perform as expected,
check the following conditions:
• Verify that the power to your TV is turned
on.
• If plugged into a wall switch, verify the
switch is in the ON position.
• Verify that all cables are properly connected.
• Verify that your TV is tuned to the proper
output channel (3 or 4).
If your DHCT does not perform as expected
after checking the power, the cables, and the
output channel, check the following conditions:
No picture
• If your system includes a VCR and/or stereo,
verify that you have properly connected
them to the DHCT.
• Verify that the DHCT power light is on and
the Bypass light is off.
No color
• Verify that the current TV program is
broadcast in color.
• Adjust the TV color controls.
No sound
• If your setup includes a VCR and/or stereo,
verify that you have properly connected
them to the DHCT.
• Verify that the volume is turned up.
• Verify that the Bypass feature is disabled.
The LED on the front panel displays
question marks instead of the channel
number.
Press the INFO key on the remote control or
the front panel of the DHCT. You may have
pressed the Power key before all of the latest
programming updates were received by the
DHCT.
The TV screen displays a message indicat-
ing that the DHCT is automatically updat-
ing its software.
Wait for the time to display on the LED before
continuing with your installation process. When
the front panel displays the time, the update is
complete.
Note: If you need further assistance, contact
your cable service provider.
