Replacing The Battery; Troubleshooting Guide - Overhead door 1056 Instruction Manual

TRANSMITTER SERVICE HINTS
NOTE:
\ If you have two transmitters, and one does not work, it is reasonable
to assume the problem is in the transmitter. However, when you
have one transmitter and it does not work the problem may be in
the receiver. When returning the controls to the factory for service,
it is always recommended that you send the receiver and all the
transmitters so they can be tested as a set.
When writing to the factory for assistance or when returning a
control for repair be sure to include the following information:
1 . Number of Transmitters
2. Door opener Model No. and
Manufacturers Name
3. Date Unit was Installed
4. Nature of Difficulty
If you have purchased only one transmitter and you wish to purchase
a second one, specify the frequency found on the white sticker on
the back of the transmitter.
REPLACING THE BATTERY:
1. Remove the visor clip by sliding it out of the groove.
2. Remove the exposed screw.
3. Squeeze the upper housing half at the grooved area and separate
from the lower half.
4. Gently pry the battery up until it separates from the clips.
5. Replace only with Overhead Door A23 or equivalent 12 volt
battery. Any other voltage may damage the transmitter and void
the warranty.
TROUBLESHOOTING GUIDE

opener, when the pushbutton or transmitter button is pushed, and
at the end of the light timing cycle. The self test shows a system
problem by flashing the opener light.
