Setting the MB 660 to flight mode
During taxi, take-off, and landing, the use of portable electronic devices is
allowed, provided that they are set to flight mode. You can use your headset
without violating civil aviation regulations by deactivating Bluetooth wireless
transmission.
There are 2 ways to set the headset to flight mode:
Deactivate Bluetooth on the headset.

Activating/deactivating Bluetooth

In instances where you just want to block out aircraft/ambient noise during a
flight, ensure that Bluetooth is deactivated and NoiseGard is switched on. To
switch NoiseGard on in full or set it to Adaptive Mode, see page 20.
Use the Bluetooth switch to activate or deactivate Bluetooth on the headset:
X
– Activate Bluetooth "I" if you want to use the wireless features of the
headset, such as pairing another device with the headset or playing music
wirelessly.
– Deactivate Bluetooth "0" if wireless transmission is restricted, such as
during aircraft taxi, take-off, and landing.

Using the audio cable

There are 2 connection modes when you use the audio cable:
– Active mode - the connection mode when the audio cable is used on the
headset with sufficient battery life.
– Passive mode - the connection mode when the audio cable is used on the
headset with empty battery. NoiseGard is inactive.
Regardless of the position of the Bluetooth switch, Bluetooth is deactivated
when the audio cable is plugged into the audio input of the headset. If the USB
cable is being used, the transmission via USB is disabled and the headset enters
the flight mode when the audio cable is plugged in.
When you are using the in-flight entertainment (IFE) system of your airline,
the audio from the IFE may be interrupted by important announcements from
the public address (PA) system. In most cases, the announcements are much
louder than the audio of the IFE. The MB 6 60 Wireless headset recognizes this
and eliminates the volume jump when the sound source switches between PA
and IFE system.
After the announcement from the PA system, the volume of the headset stays
low. If you want to increase the volume of your audio, adjust the volume on the
IFE system.
If you want to increase the volume on the headset and the volume does
not increase as usual, restart the headset by switching it off and on again.
Using the answer/end button of the audio cable
Optionally, you can play or pause music by pressing the answer/end button of the
supplied audio cable. You can also make, accept, and end calls using the button.
