3.1.1 Battery management
The electronic door handle CX2172 comes with a battery management system,
which indicates the need for battery replacement by means of a visible and audio
signal when the battery power reduces (capacity loss) during the last 1,000
operations of battery (see chapter 7.2.1 battery replacement).
The signal is given out in two phases:
The battery needs to be replaced soon.
If an authorized key is held in front of the reading unit, then the engaging of the
door handle is accompanied with flashing of red light (5 times) and 5 short
audible signals.
The battery should be replaced immediately.
If an authorized key is held in front of the reading unit, then the red LEDs flash (5
times) accompanied by 5 short audible signals. The engaging of the door handle
is delayed by 5 seconds, during which time the green LEDs flash.
The access data, the event log, the settings of the door handle and the time are
stored in the non-volatile memory and are thus retained even without power
supply, for example when changing the battery or if the battery is completely
drained. The time is written to the non-volatile memory once every 30 minutes.
When the power supply is disrupted, the clock stops after a few seconds and
continues from the last saved value once the power supply is restored.

3.7 Management accessories
3.7.1 CX2530 Keyng
Using the CX2530 Keyng administration software, it is possible to manage the
Clex private electronic locking system conveniently from the PC. In contrast to the
well-known learning - clearing system, the software provides a wide range of
functions.
The communication between the locking units and the administration software
takes place using a USB radio stick.
3.7.2 Service key
Using the service key, a user identifies himself as an administrator of the locking
system. If this key is held in front of a locking system component, then the
respective component goes into service mode, where it is possible, for example,
to create or change authorizations, make settings or to read the event log.
