Internal IR Receiver

The internal IR receiver is located beneath the ‘X’ button. The internal IR receiver can receive and

respond to commands from the D5MR (mini-remote control) and the D5LR (learning remote control).

It will also pass-thru IR remote control commands to audio sources via an emitter. An emitter must be

connected to the D5IP or the emitter outputs from the D5RH. The internal IR receiver is plasma, LCD,

and CFL friendly.

The internal IR receiver 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 RCA DSS satellite receivers that use 56kHz). If you

are sure the carrier frequencies fall within the range of 32kHz to 56kHz, you can adjust the internal IR

receiver to match them for the best range performance. The adjustment can be made through the

potentiometer located on the front of the keypad.

To adjust, proceed as follows:

1. First, try the internal IR receiver. If it works well with good range, do not make any adjustments!

2. If it does not work or has poor range (less than 15 feet), 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. Using a small blade type screwdriver, rotate the adjustment

until the desired frequency has been achieved. This can be

down by adjusting the settings in eighth-turn increments and

trying the remote.

4. If you have products in the same IR system that have

different IR carrier frequencies, you will have to adjust the

internal IR receiver to a midway position. For example, some

may operate at 38kHz and others at 56kHz. In this case, set the

adjustment to approximately 47kHz, a midway position.

Note: Some products are more tolerant of compromised

frequency settings that 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.
