PUSH TO SET (PTS)

• STFP ? - While depressing the push pad, apply power.
• STEP 3 Continue to keep the pad depressed, the device will beep 6 times. After the beeps have stopped, release the pad and the adjustment is now set. Test the adjustment 4 to 5 times and if not to your liking repeat the above steps.

*Once you found your preferred adjustment, we recommend turning off the PTS programming switch.

*TRIM POT ADJUSTMENT ONLY REQUIRED WHEN PTS PROGRAMMING IS NOT SETTING TO THE CORRECT LOCATION

*Latch bolt adjustment- If the latch bolt is not retracting far enough, turn the dial clockwise with a small flat blade screw driver. If the latch bolt is retracting too far causing the device to chatter and drop-out, turn the dial counter-clockwise until the chatter and drop-outs stop and the desired location is achieved.
