receiver for the transmitter.
c. Contact Customer Service at Stellar Industries.
3. Only some functions are operating:
a. Check to make sure the common wires for the relays are connected properly. (See Installation drawings for
details.
b. Check output voltage of the respective wires and the electrical circuits.
c. Check the fuses inside the receiver case.
d. Check the receiver label to verify the function has been programmed to the needs of the equipment.
4. You are experiencing intermittent operation:
a. Check antenna connections and antenna location.
b. On AC systems, ensure noise suppression devices have been placed across the coils of all contacts.
c. Ensure you are inside the operating range of the receiver and have line of sight to the receiver antenna.
5. Operating Range is short:
a. Check all antenna connections and transmitter operation.
b. On new installations, verify the receiver antenna is placed properly. If necessary, use an antenna mounting
