3.1.1 Battery management
The CX216x knob module 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 final 1,000
operations of the battery (see chapter 7.2.1 Battery Replacement).
Signalling happens in three phases:
The battery needs to be changed soon.
If an authorized key is held in front of the knob module, the locking access right is
issued. The engagement is accompanied by red flashing (5x) and 5 brief audible
beeps.
The battery needs to be changed.
If an authorized key is held in front of the knob module, the knob module first
flashes green for 5 seconds, then the knob module engages. The engagement is
accompanied by red flashing (5x) and 5 brief audible beeps.
The battery needs to be changed immediately.
If an authorised key is held in front of the knob cylinder, the locking authorisation
is no longer issued. The knob cylinder flashes 5 times in red accompanied by 5
short beeps.
The access data, the events log, the settings of the knob module and the time are
stored on non-volatile memory and thus retained even when there is no power
supply, for example, when changing the battery or if the battery goes completely
flat. The time is written to the non-volatile memory once every 30 minutes. If the
power supply remains off, then the clock comes to a standstill after a few seconds
and starts running from the last stored value onwards after the power supply is
restored.

CX2162/66 OPERATION
15
6Operation
6.1 Automatic wake up
The knob module is in sleep mode as long as it is not used. To check the
authorisation of a key, it needs to be woken up from the sleep mode. This
normally happens automatically when a key is held in front of the reader unit.
If, however, the knob module has been woken up 24 times (for example by
metallic objects in the surroundings) without reading a key, then automatic wake
up is disabled.
In this case the knob module has to be woken up manually.
Turn the knob module few times to wake up the reading unit, till an LED
starts glowing.
Hold up the key in front of the reading unit only after this.
The automatic activation is reactivated when an authorized key is scanned.
