DECIDE WHAT CHANNEL TO USE: If combining with an antenna system, choose UHF channel 14-71. If combining with a cable
system choose a CABLE channel 66-94, 100-127. Choose a channel that is not currently in use by any local broadcast, cable, or other
modulated source. There must also be at least one blank channel separating each modulated channel from these other sources.
CALLER-ID: Requires a telephone line with Caller-ID service activated by the local telephone company. After the first or second ring,
the Caller-ID information will be displayed for approximately 15 seconds. The CTV1-M overlays the Caller-ID information on the video
of the modulated channel.
