You are able to see errors and operating errors in the status messages of the LED display and then correct
them accordingly.
Reset should be carried out in the case that other non-defined conditions arise and the lock does not operate
flawlessly even though the battery has been replaced. This resets the lock to factory default settings and all
programming is deleted. You can obtain the instructions for this via the address or telephone number stated
on page 2.
Replacing the battery
1. Loosen the screw on the side of the cover using a TG 6
screwdriver.
2. Open the battery compartment and remove the battery pack.
Disconnect the two-pole plug-in connector from the battery pack.
3. Connect the new battery pack to the plug-in connector and
insert the battery into the housing.
4. Close the battery compartment and screw down.
Codes are not deleted when a battery is replaced.
Notice: Please dispose the empty battery pack properly in accordance with the valid
environmental regulations!
Battery monitoring / battery alarm
Automatic battery monitoring on the SAFE-O-TRONIC®-LS 100 ensures that a SAFE-O-TRONIC®-LS 100
with inadequate battery voltage can no longer be operated.
There is an advance warning when all the LEDs flash twice. In this case it is recommended to replace the
battery.
An alarm is triggered after a while if the battery is not replaced. This is indicated when the red and green
LEDs light up in turn three times. The battery must now be replaced. In this instance the compartment can
only be opened but no longer locked.
The lock must only be operated using batteries approved by Häfele. The use of non-approved batteries can
lead to malfunctions and lock damage.
Maintenance and care
The SAFE-O-TRONIC® LS 100 is maintenance-free. In no case should the lock be oiled or greased with
lubricants containing mineral oil.
Only use non-stick, residue-free cleaning agents and disinfectants for cleaning purposes. Do not use any
heavy cleaning agents, acids or lyes when caring for the product. Also do not use a pressure cleaner. It is also
not recommended to spray-wash the locks, for example using a hose.
