Erase memory
In cases where the Codoor is moved to another door (with new
users), you should be sure that no old codes remains. The best way
is to erase the memory. Proceed as follows:
Remove Codoor from the door.
Press and hold the reset button on the rear of Codoor
and -button simultaneously - until the green LED
lit.
Release both buttons simultaneously.
Press the reset button once again for 2 seconds.
As a confirmation, a rising tone sounds from the buzzer.
