If you experience distinctive problems with the Transmitter and
Receiver, try some of the suggestions listed belo w before calling
the Factory Technicians.
RECEIVER APPEARS DEAD; THERE IS NO RESPONSE WHEN
TRANSMITTER BUTTONS ARE PUSHED.
Check the power connections to the receiver.
There must be at least 20 VAC at the receiver power
connections. (If a 24V system).
Review the code switch settings.
Any mismatch will prevent the receiver from working.
Try a different code switch se t ting.
Check the antenna installation.
Wait one minute for the receiver to “warm-up”.
Check battery in transmitter.
RECEIVER “CLICKS” WHEN ANY TRANSMITTER BUTTON
IS PUSHED, BUT NOTHING ELSE HAPPENS.
Check the wire & conn ections in the STOP circuit. Refer to
Figure 3.
Check the OPEN & CLOSE connections.
The wire gage may be too small for the number of wall
statio ns used.
Check the power to the door operator.
Check the door operator’s control voltage.

SHORT DISTANCE OR INTERMITTENT OPERATION.

Relocate the antenna with a coaxial cable.
Metal objects too close to receiver, move to a better
location.
External interference (such as radio towers).
Change to a differe nt frequency.
Stuck transmitter in building.
Change code switche s from factory settings.
Check battery in transmitter.

ONE RECEIVER WORKS BUT THE OTHER IS DEAD.

Relocate the antennas.
Receivers too close together (cross-talking); move to
different locations.
Use a Master/Slave system.
Master/Slave wires not connected properly. Refer to
FigureZ4.
Check code switch settings.

SOME THINGS TO REMEMBER:

Range is dependent on the installation, type of building,
type of door an d the location of th e tran s mitter. When th es e
conditions change so will the distance.
Any transmitter can interfere with operation. These include
cell phones, cordless phones, wireless systems and CB and
mobile transmitters. Other sources of interference include
computer equipment, industrial equipment, electric motors,
fluorescent lights, etc. The list is endless.
Do not lengthen or shorten the receiver antenna. It is set to
an optimal length based on the frequency of operation.
If the antenna is blocked or shielded (such as a car traveling
through a tunne l) the distanc e will decrease.
Always change the Factory set codes.
