TROUBLE SHOOTING
1. Perhaps the most common problem is
stray IR or RF interference entering IR
receivers, preventing proper operation
of the controlled equipment.
Examples of such interference are:
• Fluorescent, Compact Fluorescent,
Neon or Halogen lights, Neon Art, or
light dimmers.
• Direct or reflected sunlight.
• Infrared security sensors (active type).
• RF radiation from TV sets that may be
close to IR Receivers.
It may be necessary to move either the
interfering source or the IR receiver to
achieve proper operation. Sometimes
the Xantech Sun Filters will help.
2. If the IR receivers must operate in the
vicinity of electronically ballasted Com-
pact Fluorescent lamps or sunlight con-
ditions, use Xantech models 291-80 or
780-80 IR receivers. These are specifi-
cally designed to reject most of this type
ofinterference.
3. Check for shorts or opens anywhere
between the IR receivers in the remote
rooms and the emitters at the controlled
equipment.
•Remember, you must have DC conti-
nuity all the way from the IR (IR RCVR)
jacks on the Injectors, through the coax
cables to the IR (emitter) jack on the coupler, without shorts to ground.
• Use a Xantech
Test-IR
TM
plugged into the IR (emitter) jack on the coupler to verify that the IR
signal is being received from each room.
• If necessary, use a multimeter in the low Ohms range to check for continuity, shorts, opens, etc.
• Check for open emitters by substituting a known good emitter.
4. If a given component still does not work, reposition the emitter. It may not be located directly over the
component’s IR (infrared) receiving "window". Consult the owner's manual of the unit or the
manufacturer for the exact location of the infrared "window".
