Operation
WARNING
Risk of explosion
The use of an unsuitable smartphone in an explosion-hazard
area may lead to the ignition of flammable or explosive
atmospheres.
► The smartphone must be suitable and approved for use in
explosion-hazard areas.
®
The Bluetooth feature is not part of the technical suitability
test and may only be used in countries for which approval is
available. Contact Dräger if you have any questions about
availability.
Contamination of the gas detector or shielding elements
(e.g. case) can reduce the Bluetooth
Failure of the Bluetooth® communication of the gas
detector is to be expected in the vicinity of strong transmitters
in the range of the 2.4 GHz band.
When connecting a new smartphone, the connection that is
currently stored is deleted during this process.
1. Switch on the gas detector.
2. Call up the Quick menu: Press
®
3. Select Bluetooth connection and confirm.
4. Select the gas detector on the smartphone:
a. Short name of the gas detector in the Android/iOS
®
Bluetooth menu.
b. Part number and serial number in optional Dräger app.
A 6-digit number is displayed on the smartphone and
on the gas detector.
5. Check that the numeric code on both devices match and,
if they match, confirm on both devices. The devices must
be coupled within 20 s otherwise the numeric code will
become invalid.
✓ Coupling of the devices is complete.
Once a connection has been successfully established, it is
saved and the two devices are automatically connected in
the future (adjustable via the CC-Vision PC software).
If the connection is lost, the gas detector automatically
tries to establish a new connection.
A connection to the Dräger Connectivity Hub is
established automatically if the gas detector is registered
to the same tenant as the Dräger Connectivity Hub. For
more information, see the Dräger Connectivity Hub
instructions for use.
A short tone sounds to indicate that a connection is being
established.
A double tone indicates that the connection has been
terminated.

4.6 During operation
WARNING
Danger to life and/or risk of explosion!
The following alarms indicate a danger to life and/or risk of
explosion:
– A2 alarm
– STEL or TWA alarm
– Device/channel error
► Immediately leave the hazard area.
WARNING
Incorrect measured values!
Only for diffusion mode: If water seals the gas inlets on the
gas detector (e.g. in heavy rain or if the gas detector is
submerged in water), incorrect measured values may be
returned.
► With the display facing downward, shake the gas detector
to remove the water.
WARNING
Incorrect measured values!
A different reading may be shown if the gas detector
experiences a considerable impact or a significant vibration.
► When using a CatEx or IR sensor (depending on the gas
detector type), a calibration of zero-point and sensitivity
must be carried out after an impact load that results in a
fresh air display not equal to zero.
CAUTION
The volume of the horn is reduced!
If water gets into the opening on the horn (e.g. by immersing
the gas detector in water or due to heavy rain), the volume of
the horn can be significantly reduced.
► With the display facing downward, shake the gas detector
to remove the water.
®
Only using Bluetooth or API applications is insufficient for
raising the alarm in safety-critical applications. Raising the
alarm on the gas detector is decisive.
Contact Dräger for a description of the API interface.
Dräger recommends limiting the usage time at
temperatures below -20 °C, as the rechargeable battery life
and the display may be restricted.
At temperatures below -25 °C, there may be limitations to
what is shown on the display. Dräger then recommends only
using the alarm elements as a display.
WARNING
High readings outside of the LEL display range or a protection
alarm may indicate an explosive concentration.
If the concentrations of combustible gases are too high, this
may be the result of a lack of O
