REPLACING THE TRANSMITTER BATTERY

The lithium battery should produce power
for up to 5 years. To replace battery, pry
open case with visor clip or screwdriver,

Dispose of old battery properly.

SET OUTPUT DURATION
(COMMERCIAL APPLICATIONS ONLY)

For commercial applications, the receiver can be set for either
constant or momentary closure on the output contacts. Use of
constant closure is prohibited on residential garage door openers
because it overrides the safety reversal devices.

With the jumper in the “M” (Momentary) position, the contacts will
close for 1/4 second regardless of the length of radio transmis-
sion. With the jumper in “C” (Constant) position, the contacts will
stay closed as long as the radio continues transmitting.

The receiver is factory set at M.

To prevent possible SERIOUS INJURY or DEATH, the use of 
CONSTANT OPERATION on residential openers is PROHIBITED.
