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
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
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.
