ADJUSTING THE IR CARRIER FREQUENCY
The 29185D is factory set to an IR carrier repeat frequency of 38kHz. This
will be correct for the majority of installations. However, some manufacturer’s
components that you wish to control may use different carrier frequencies
(such as the RCA DSS receivers that use 56kHz). If such carrier frequencies
fall within the range of 32kHz to 56kHz, you can adjust the 29185D to match
tem for best range performance. The adjustment can be made through the
small thumbwheel on the rear of the unit.
To adjust, proceed as follows:
1. First, try the IR receiver in the system. If the system controls all the
desired components with adequate range, do not make any
adjustments.
2. If the system does not work or has poor range, determine the IR
carrier frequency of the product you wish to control. Contact the
manufacturer of the product, if necessary, to determine this
frequency.
3. Facing the rear of the unit, rotate the thumb-wheel adjustment
slightly either left to obtain carrier’s less than 38kHz or right to obtain
carrier’s greater than 38kHz .
4. If you have audio/video equipment in the same system that has
different IR carrier frequencies, you will have to adjust the IR receiver
to the midway position. For example, some products may operate at
38kHz and others at 56kHz. In this case, set the adjustment in
between this range so both products can operate in the system.
Note: Some products are more tolerant of compromised frequency settings than
others. You may have to “fine tune” the adjustment to “favor” the least tolerant
component for the best performance of all units in the system.
TROUBLE SHOOTING:
1. Perhaps the most common problem you may encounter is stray IR
(infrared) or RF (radio frequency) interference preventing proper
operation of the controlled equipment.
• Fluorescent, Compact Fluorescent, Neon or Halogen lights,
Neon Art, and light dimmers.
• Direct of reflected sunlight.
• Infrared security sensors (active types).
• RF radiation from TV sets that may be close to the Hidden
Link IR Receiver.
2. You can confirm the source of the interference by temporarily turning
off TV sets, isolating the Hidden Link IR Receiver from all sunlight
and turning off all lights, light dimmers and Infrared security systems.
Then check to see if the Hidden Link IR Receiver operates the
component.
• Sometimes interference will cause the red Talk-Back LED on
the front of the Hidden Link IR Receiver to blink dimly,
intermittently, or continuously.
• The Talk-Back Led should only blink when you are sending
infrared commands to the Hidden Link IR receiver from a
remote control.
• It may be necessary to move either the interfering source of
the Hidden Link IR Receiver to achieve proper operation.
3. If the Talk-Back LED or the 286D Emitters do not blink when you are
sending IR commands to the Hidden Link IR Receiver from a remote
control, check the following:
• Make sure the power supply is plugged securely into a live
AC electrical outlet.
• Be sure the stereo mini plug of the Hidden Link IR Receiver
is plugged into the “IR RCVR” jack on the CB12 Connecting
Block, not into the “OUT” jack.
• Check to see that all the mini plugs are properly seated into
the mini jacks on the CB12 Connecting Block.
4. If the 286D Emitters blink, but the component does not respond,
reposition the 286D Emitter(s). They may not be located directly over
the component’s infrared receiving “window”. Consul the owner’s
manual of the unit or the manufacturer for the exact location of the
infrared “window”.
