[. . . ] Set the mono /stereo switch F to the desired position: = mono = stereo Using Smart Update The noise level in the cockpit changes depending on the flight situation. Whenever you perceive a change in the noise level (e. g. during take off and when the cruise altitude is reached), you should perform the Smart Update in order to ensure optimum noise compensation at any given time. The outer and inner microphones measure the sound and NoiseGardTM/digital is adjusted accordingly via the electronics. Smart Update only works when the headset is switched on. The Smart Update button lights up for approx. 4 seconds and you hear an acknowledgement tone, indicating that NoiseGardTM/digital is adjusted to the noise level. S1 DIGITAL | 19 Using the S1 DIGITAL Activating the "auto shut-off" function The "auto shut-off" function automatically switches the headset off when it is disconnected from the intercom or when the aircraft avionics are switched off.

Switching the 3-step treble boost on/off The switches for the 3-step treble boost allow you to individually adjust the speech intelligibility for the left and right channel separately.
