User's Manual

The receiver can be set for either constant or momentary
closure on the output contacts. With the jumper in the
“MOM” (Momentary) position, the contacts will close for 1/4
second regardless of the length of radio transmission. With
the jumper in “CONST” (Constant) position, the contacts
will stay closed as long as the radio continues transmitting.
The receiver is factory set at M.
TO SET OUTPUT DURATION
The use of radios incorporating constant closure
contacts on residential operators with fail-safe
infra-red protectors is prohibited.
WARNING
The receiver can be powered with either 24V AC/DC or
with 12V DC. The jumper must be in the 24V position for
use with 24V, and in 12V position for use with 12 VDC. The
jumper must be set to the proper voltage to avoid
damage to the receiver.
The receiver is factory set at 24V.
The jumper must be set at the HIGH position for the
receiver to operate in high security mode. It must be set at
NORMAL position to operate at the normal mode.
When changing from normal to high security mode, any
previous transmitter codes must be erased. Repeat Steps
1 and 2 on Side 1 to reprogram the receiver for each
remote control transmitter in use.
The receiver is factory set at HIGH.
TO SET POWER SUPPLY VOLTAGE
TO SET SECURITY MODE
The use of 24V with the jumper in 12V position will
cause permanent damage to the receiver.
