Connecting a mobile telephone
The 2.5 mm jack socket allows you to connect a mobile
telephone. For this purpose, the microphone plug must be
connected to the aircraft radio/intercom. A suitable adapter
for your mobile telephone with 2.5 mm jack socket is
available from your Sennheiser agent.
Note:
For the latest list of compatible mobile telephones, please
refer to the “Cell Phone Compatibility” section on our
website at www.sennheiser.com. Search under
“Products”, “Aviation” and “more info …”.
̈ Connect the audio cable to the 2.5 mm jack socket on
the operating control and to the corresponding jack
socket on your mobile telephone.
You can adjust the volume of the mobile telephone via
the headset’s operating control. However, the functions
of the mobile telephone cannot be controlled via the
headset’s operating control.
̈ Switch NoiseGard 2.0 on (see “Switching NoiseGard on/
off” on page 16).
Audio from the mobile telephone and from the intercom
are heard simultaneously through the headset.
̈ Operate your mobile telephone as usual and observe the
manufacturers instructions.
DANGER! Danger of accident due to reduced
attention!
Making telephone calls or operating the
mobile telephone limits your attention and
may cause accidents.
̈ During flight operation, do not use the
headset for telephone calls!
