12 Changing the batteries
When the unit’s batteries run out, Codoor will stop working.
The lock has a backup power supply that will allow the door to
be opened a limited number of times, but the batteries should be
replaced as soon as they fail. Follow these steps:
1. Remove Codoor from the door.
2. Remove the batteries from the rectangular shaped holes on the lower part
of the back of the unit (2 batteries type U9VL).
3. Always change both batteries. Changing only one battery will
dramatically reduce the life of the new battery. The batteries should be
lithium type.
4. Re-fix the housing.
13 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:
1. Remove Codoor from the door.
2. Press and hold the reset button on the rear of Codoor
and - button simultaneously - until the green LED
lit.
3. Release both buttons simultaneously.
4. Press the reset button once again for 2 seconds.
5. As a confirmation, a rising tone sounds from the buzzer.
