CHANGING THE MASTER CODE
It is highly recommended that you change the default master code and to choose the longest possible and secure
master code.
The lock must be in open position. There must be no battery warning.
The master code must be 3 to 10 digits.
If you have already changed the default master code, enter your valid master code here. In order to confirm the
master code, press the keys

simultaneously.
After the enter button is pressed the LED display will turn to a continuous red light until a new master code has been
entered for the first time.
Now carefully enter the new master code 2x in succession (as described in the following). When entering the new
master code, make particularly sure that the LED display acknowledges each key input.
If the new master code has been entered correctly twice, there is a long green flashing in the LED display. The new
master code is valid. In all other cases, the LED display flashes red ten times. The new master code was not accepted.
The previous master code is still valid.
Perform immediately a functional test with the new master code!
