Alarm settings (factory setting)
Definition:
Pre-acknowledgement: If, during the alarm condition, the acknowledgement is actuated (by pressing the OK button), the audible
alarm and the vibration are switched off. The alarm is only fully reset (LED and display) once the alarm condition no longer
exists.
Acknowledgement: If an acknowledgement is actuated when the A1 alarm condition no longer exists (by pressing the OK
button), all alarm elements will be reset.
If the A2 and A1 alarms are configured as acknowledgeable, a pre-acknowledgement or acknowledgement of the A2 alarm
will pre-acknowledge the A1 alarm or fully acknowledge it if no further alarm condition exists.

1) The STEL alarm can trigger with a delay of up to one minute.
2) The work being carried out must be regulated in accordance with national regulations after this alarm.
3) A TWA alarm can only be reset by switching the gas detector off and then on again.
4) For troubleshooting, see the Technical Manual.
5) The battery will last another approx. 10 minutes once the battery pre-alarm has been triggered.
6) The gas detector automatically switches off after 20 s when the battery main alarm is triggered.

Transport
The gas detector contains lithium-ion batteries. During
transport, in particular air transport of the gas detector, adhere
to the relevant safety regulations and markings for lithium
batteries.
After completing the measurement, use the protective cap
designed for transport and storage of the pump and
calibration adapter.
8
Storage
Dräger recommends storing the gas detector in the charging
cradle.

The sensors are supplied with power even when the gas
detector is switched off to ensure a faster warm-up time when
switching on.
When storing the gas detector outside of the charging cradle,
power supply to the sensors is cut off automatically after
21 days. When the gas detector is switched on again, there is
an increased warm-up time.
For calibration adapter CAL 2.0 (3720224) and pump adapter
"Nona" (3720225) the following applies:
For storage, disconnect the pump and calibration adapter
from the gas detector and store it separately with the
designated protective cap. This applies in particular if the gas
detector is used in low temperatures (below 0 °C) or if use is
planned at below 0 °C.
