WARNING
SET SECURITY MODE
CAUTION
The Universal Receiver can be used with up to 15 rolling code
transmitters or passwords in HIGH security mode. Alternately, it
can be used with up to 31 of any type transmitter in NORMAL
security mode, including any combination of rolling code, billion
code, or dip switch remotes.
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 (Figure 1).
When changing from NORMAL to HIGH security mode, any
previous transmitter codes must be erased. Repeat Steps 2 and 3
in the Programming Section below to reprogram the receiver for
each remote control transmitter in use.
The receiver is factory set at HIGH.
SET OUTPUT DURATION
WARNING
To prevent possible SERIOUS INJURY or DEATH, the use of
CONSTANT OPERATION on residential openers is PROHIBITED.
CAUTION
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
transmission. With the jumper in "C" (Constant) position, the
contacts will stay closed as long as the radio continues
transmitting (Figure 2).
The receiver is factory set at M.
PROGRAMMING THE REMOTE TO THE RECEIVER
1. Pry open the front panel of receiver case with a coin or a
screwdriver. Re-connect power to opener (Figure 3).
2. Press and release the "learn" button on the receiver. The learn
indicator light will glow steadily for 30 seconds.
3. Within 30 seconds, press and hold the button on the hand-held
remote that you wish to operate your garage door.
The opener will now operate when the push button on either the
receiver or the remote control transmitter is pressed.
Repeat Steps 2 and 3 for each remote control that will be used to
operate the garage door opener.
TO ERASE ALL REMOTE CONTROL CODES
Press and hold the "learn" button on the receiver panel until the
