Sample System Diagram  
Things to watch for:  
No picture … Verify that the video source is on and is producing a video signal. Check that the  
TV and the modulator are tuned to the same channel. For example, if the modulator is  
broadcasting on UHF channel 16, make sure the TV is on UHF 16 rather than CATV 16. UHF 16  
and CATV 16 are at different frequencies.  
SATELLITE  
RECEIVER  
In this system, CATV or antenna  
channels are available on all TVs. In  
addition the following channels have  
been added:  
Weak ChannelPlus UHF channel … If the TV has a separate UHF input, be sure that it is  
connected.  
LEDs blink ... You need to have one unused channel space between channels. The display will  
blink if you have made an ‘illegal’ choice. See the section on programming.

Herringbone interference on ChannelPlus channel (diagonal lines) ...  
You may have chosen a channel number that is not completely vacant. Distant UHF stations may  
be un-watchable, but will cause interference if you try to create a new channel at the same  
frequency. Also, cable companies often have extra signals where there should be none. Try  
moving the ChannelPlus channel to another number. You may have to add a low pass filter to  
remove cable company noise. If a filter does not work, try adding a DC-block to remove common  
mode interference.  
Model 3445  
Herringbone interference on many channels, including ChannelPlus  
channels (disappears when you remove the CATV/Ant feed) … The RF amplifier can be  
overloaded by abnormally strong signals. Often, you can cure the problem with a simple  
attenuator. Use a variable attenuator and try to find a signal level where the interference just  
disappears. Sometimes, the problem is one station that is far stronger than the rest. In this case  
attenuating all of the signals with a simple attenuator will cause the desired stations to be weak  
(snowy). In this case you must reduce the strength of only the offending station. A common FM  
trap will help if the problem is a nearby FM tower. If the problem is a nearby TV station, often the  
station management can provide suitable filters.

Audio volume is low … The left and right audio inputs are combined for monaural. For proper  
audio level, both right and left inputs must be used. If you have a mono source, connect it to both  
right and left inputs using an RCA ‘Y’ connector.

No color on ChannelPlus channels You may have chosen the incorrect cable standard. Not  
all televisions can accommodate the 1.25MHz frequency difference between the H and I cable  
standards. See the section on programming.

Infrared Remote Control Problems … Use the red IR DATA light on the side of the modulator  
section as a trouble shooting aid. This light will blink as remote control signals are relayed.  
If the light is on constantly, one or more IR targets is receiving electrical or optical noise. At the  
modulator section unit, begin to disconnect the outputs to the TVs until the IR DATA light goes off.  
This will tell you which IR target is the source of the noise.  
Next cover the front of the offending IR target. If the IR DATA light turns off, the IR target is  
‘seeing’ a source of IR noise, such as a solid state flourescent lamp. If the light does not go out,  
the problem may be radiated electrical noise from the TV. Reposition this IR target. If  
repositioning the IR target does not help, the TV may be conducting noise from its input. Place a  
DC block between the IR target and the TV.

If the IR DATA light seems to indicate proper operation, but the component is not being controlled,  
the IR emitter may be mis-located. Be sure the emitters are in front of the IR sensor.
