OPERATING THE SET-TOP (cont.)
Tuning the TV and VCR to the set-top
The set-top’s RF output port (labeled “TO TV”) can transmit signals on either channel 3 or channel 4. The
cable operator has set up the set-top to transmit on the channel that is suitable for the installation location and
should have told you which channel this is. You must tune the TV and the VCR to this output channel so that
programs can be watched and recorded through the RF coaxial cables. To do the tuning, refer to the diagram,
right, and the manuals supplied with TV and VCR, if necessary, then carry out the following steps.
1. Make sure that all the equipment, including the set-top, is turned on.
Make sure that you have selected the RF input at the TV.
Make sure that the Bypass feature is turned off (BYPASS is NOT lighted on the front panel).
2. On the VCR, switch the TV/VCR switch to “TV”.
3. Tune the TV to the set-top’s RF output channel (3 or 4, as stated by the cable operator).
You should now be able to see on the TV a program that is coming from the set-top. If you cannot, check that the
RF coaxial cables are securely and correctly connected (see the setup diagrams). If there is still a problem, check
with the cable operator that you are using the correct RF output channel.
4. When you can see a set-top program on the TV, switch the TV/VCR switch on the VCR to “VCR”.
If you can still see the picture on the TV, everything is tuned correctly. If the picture disappears, carry out the
following final step.
5. Tune the VCR by setting the VCR’s RF output channel to the same RF channel number as the set-top and
TV (either 3 or 4, as stated by the cable operator).
Everything should now be tuned correctly.
NOTES
Regardless of the program channel number selected on the set-top (and shown on its front-panel
display), the RF output channel number will always be fixed (either 3 or 4, as quoted by the cable
operator). The TV and VCR must be tuned to this channel if you want to watch and record programs
through the RF coaxial cables.
