Q- Do I need the bypass kit if I use the A/V cables to connect the cable box to the TV?
A- No. You only need the kit when you use the coax output of the cable box. Split the coax before the cable box. Connect
the cable box to the TV’s A/V input and the bypass coax to the the TV’s RF input. Use the TV remote to switch the TV from
the A/V input to the modulator channel.
Q- Do I need the bypass kit if the TV has two coax inputs?
A- No. You only need the kit when you use must combine the coax output of the cable box with the bypass coax in order
to go into the same input of the TV. Split the coax before the cable box. Connect the cable box output to one RF input
and the bypass coax to the other RF input. Use the TV remote to change RF inputs on the TV (ANT1, ANT2) and then
select the modulator channel.
Q- Why can’t I see the modulator on the cable box, even after I installed the bypass kit?
A- Most cable boxes are setup to only tune the cable company’s channels. The purpose of the bypass kit is to send the
modulator signal directly to the TV for tuning. Therefore, you will have to use the TV’s remote instead of the cable box
remote. Change the TV from the cable box channel (3 or 4) to the modulator’s channel.
Q- Why does the modulator signal look snowy after I put in the bypass kit?
A- The bypass kit will reduce the strength of the signal that passes through the filter and splitters. Try turning up the gain
of the modulator or amplfying the signal at the head end of the distribution system to compensate for the loss. Make
sure the modulator looks good without the bypass kit. Also make sure the kit is installed according to the diagram.
Q- Can the bypass kit be used with digital cable service?
A- Yes. When the kit is properly installed, the digital service has a clear path to the cable box; the signal does not pass
through the filter. Even so, the filter only removes low VHF frequencies which are not near the typical digital range above
channel 80.
Q- Does this filter make clear channels for the modulator?
A- No. Any splitters, amplifiers or filters that you use for combining signals together are separate from the ones used to bypass
the cable box. If there are no clear cable channels then you will need an additional filter, such as NetMedia’s NM-CNF7080,
at the head of the distribution system. The filter goes on the cable service before it combines with the modulator.
Figure 1 - Bypassing a digital or analog cable box and recombining to a single coax input on the TV. The NM-ACB3
filter removes any conflict with the cable box on channel 3 or 4. The NM-CNF7080 filter removes any
conflict with the cable service on channels 70-80. Switch the TV from the cable box channel (3 or 4) to
the modulated channel (70-80).
