Acoustic and light signals are the same as for programming the «master-code».
4.Changing the batteries
If the voltage is low, every time a button «*» is pressed an acoustic buzzer signal
sounds 5 times and the red LED flashes. Such being the case, it is possible only
lock opening and it is not permitted to press ENTER for code change, following
by a single buzzer signal and a red LED flashing.
Use only 4 1.5V-Alkaline-Batteries Type AAA for the power supply to the lock.
The battery is placed in the low part of the keyboard body under the removable
cover. Replace the old battery with new one by observing the polarities. The
code remains saved even if the battery is switched off.
5. Malfunction diagnostics
During power-up the device a self-test is performed. If the access code is
damaged, the buzzer signal sounds 3 times and the two LEDs are flashing. The
device switches off.
If a change of one of the codes is made and it is impossible to save the new one, the buzzer signal sounds 3 times and the two
LEDs are flashing. Then the device function is continued with the former code being valid before the unsuccessful attempt to
change the code.
In the event of a problem when changing the code, please contact to closest the located customer service.
