MATCHING SECURITY CODES
It may be necessary to program the remote receiver to the 
security code of the transmitter upon initial use, if batteries 
are replaced, or if a replacement transmitter is purchased 
from your dealer. To program the remote receiver: 
1.  Set the slide button on the receiver to the REMOTE 
position.
2.  Push the LEARN button (one beep will be heard) on the 
top of the remote receiver. 
3.  Then press the MODE button on the transmitter. Several 
beeps indicate the transmitter’s code has been pro-
grammed into the receiver. When an existing receiver is 
matched to a new transmitter, the new security code will 
overwrite the old one. NOTE: When the LEARN button 
is depressed, “beeping” sounds should be heard. If no 
“beeping” is heard check to see that the receiver has 
110-120VAC power to it.
If you are unsuccessful in matching the security code on 
the fi rst attempt, wait 1-2 minutes before trying again.

Flip open the plastic cover on the front of the transmitter 
to expose the “SET” buttons. 
NOTE: Flashing numbers on the display indicate the sys-
tem is waiting for input, such as using the UP and DOWN

fl ashing digits within 15 seconds, the system will complete 
the procedure last programmed and reset the display to 
its normal state.

3. After setting the desired hour, press and release the 
TIMER/TIME button again to set the minutes; the minute 
digits will begin fl ashing.
4.  Press the UP or DOWN button until the desired minutes 
are displayed.
5.  Press and hold the TIMER/TIME button again for more
