Whisper Mode
In situations where talking at normal volumes may be an issue the radio supports a high sensitivity microphone mode
that can be toggled. You radio has a single audio input through the CE connector. The microphone can be fed from
the inductive loop or the inductive patch. Although these devices have different audio characteristics, the Whisper
Mode microphone gain delta is constant. This feature can be activated by pressing OPTION button.
Note: Whisper Mode is deactivated at power on.
Audio Features
There are many situations where the demand of audio quality changes according to the working environment. For
example, an airport worker, who works partly in the field where there is lots of noise coming from the surrounding
environment and partly inside the airport where there is relatively less noise, may experience different audio quality.
In the working environments like these ones, there is a need for different audio quality and adaptive audio parameters
which can be configured according to the working environment.
