XI. Simple Troubleshooting
1. After the installation of lockset and batteries, the
door will not lock and three short beeps are heard
when you press the Programming button.
Cause: The door-handling identifying process is not yet complete.
Solution: Please execute the door-handling identifying process as
soon as the installation of the lockset is completed.
2. After the installation of the lockset and batteries,
there is no response when you press any button
(no sounds are heard, and the backlight does not
work).
Cause: It could be a problem caused by the batteries or improper
connection of the cable.
Solution: Check to see if the battery polarities have been reversed
or if the battery is dead. If so, please re-install or change
the battery. If not, please check if the cable is
appropriately connected.
3. Failure the first time when executing the door-
handling identifying process (the red light flashes
three times, and three short beeps are heard).
Cause: Wrong door-handling or door-handling in the memory was
changed.
Solution: Press the R button to restore the system to factory default
setting and re-execute door-handling identifying process.
4. Although the first execution of the door-handling
identifying process succeeded, the latch does not
work. (It seems that the motor runs but the latch
bolt is stuck, and the turn piece inside can be
rotated.)
Cause: Low battery.
Solution: Please replace with new batteries.
5. The lock has been functioning normally, but
suddenly, the latch bolt locks up, and the turn
piece inside cannot be rotated, not even with the
key.
Cause: The detection of latch bolt position is abnormal.
Solution: Please take out one battery first, then press any button on
the front panel for electric discharge, and put the battery
back.
The latch bolt will automatically re-detect its position
subsequently.
Warning: If the latch gets stuck frequency, please check if the
opening of the strike aims at the central position of the
latch bolt, if the latch bolt can extend freely, or if the
hinges are deformed or tilted.
