Follow these steps when troubleshooting the CommandPro

receivers.

1. Check the POWER indicator. If POWER is not illuminated:

a. Make sure the power switch on the right side of the receiver cabinet is in the ON position.

b. Check for AC input power between terminals X1 (X1/+DC-SW for R14A) and X2 of the terminal

strip. If AC power is present and the POWER on LED is not on, the problem may be in the Relay

board.

2. Ensure the transmitter is OFF.

a. Switch the receiver power switch off and then on. If no indicators come on after one second, the

microprocessor circuits are possibly defective. The RF/Decoder board may also be defective.

3. Turn the transmitter ON. The SIGNAL LED should start to flash. If it does not:

a. Test the transmitter.

b. Verify that the ID Code is the same for the transmitter and receiver.

4. Turn the transmitter ON.

a. Change the ID Code on the transmitter or receiver so that they are the same. Refer to Changing the

Transmitter ID Code for instructions on setting the ID Code.

5. If only some functions are operating:

a. Check to see if the relay LEDs illuminate for inoperative functions.

b. Check the output voltage of the respective relays and the electrical circuits.

c. Check the condition of the transmitter switches.

d. Check the configuration sheet to verify that the problem function has been programmed to the

needs of the equipment.

6. If you are experiencing intermittent operation:

a. Check all connections; make sure that terminal strips are firmly snapped in place and that the

RF/Decoder board is firmly attached to the back of the Relay board.

b. Check the antenna connections.

c. On AC systems, ensure that noise suppression devices have been placed across the coils of all

contactors.

7. If the operating range is short:

a. Check all antenna connections and transmitter operation.

b. On new installations, verify that the receiver antenna is placed properly.

c. If necessary, use an antenna mounting kit to relocate the antenna to a more favorable location.

8. If a new board (21R22 only) does not work:

a. Check that the jumper for BD1, BD2, etc. is in the proper place.
