Symptom

Probable Cause

Remedy

This is commonly caused by a security motion detector aimed at the keypad’s IR receiver. If possible, redirect the motion detector. Try to keep the keypad from strong direct sunlight. This can also cause interference. This can also be caused by an incorrect wire pinout at the CAT5 RJ45 termination. Check using a CAT5 tester and re-terminate if necessary.

The IR repeater does not properly control the audio source equipment.

One or more of the IR emitters are not properly placed over the IR receiver on the audio source equipment, or the IR output on the Simplese does not correspond with the audio equipment you are controlling.

Reposition the LED end of the emitter on the face of the source equipment, so it is flashing directly over that source’s IR receiver. Make sure that the emitter plugged into IR Output #1 is actually going to source #1 , and so on for sources 2-4.

External amplifier (NuVo P2100) or other

Ground loop.
