Use the NetMedia ACB3 Cable Box Bypass/Combiner Kit to pass a modulator signal to the TV tuner without disrupting the
output of a digital or analog cable box. Most cable boxes will only tune cable service signals. Therefore, the TV must be used
instead of the cable box to tune other signals. The ACB3 permits this by splitting the cable signal and filtering out channels
3 and 4 before recombining with the cable box which outputs an independent channel 3 or 4.

Installation Procedures:
1. Set the modulator according to its directions. Choose an unused channel with at least one blank channel on either side
to separate it from any other broadcast, cable, or modulated sources. Be aware that digital cable data typically interferes
with channels above 80, even though they appear unused, and even when the location is not subscribed to digital
services. Channels 120-125 sometimes work without filtering; any filter required to clear a channel range from the main
cable service would be separate and in addition to the one included with the ACB3 (NetMedia CNF7080 removes cable
channels 70-80). Also, the TV analog channels 120-125 are not the same as the cable box digital channels 120-125 so they
will not interfere with each other.
2. Combine the modulator and cable service at the beginning of the distribution system. This should be before any other
splitters except for ones that are dedicated to Internet service. Make sure not to use any diplexers to split or combine
because they will severely degrade whichever signal is connected to the SAT input/output.
3. Install an ACB3 Kit as shown above wherever there is a cable box that is connected to the TV’s only RF cable/antenna input.
4. Use the cable box tuner/remote to view cable programming while the TV is set to channel 3 or 4. Use the TV tuner/remote
to switch it to the modulator channel.
