6.2 Other programmable features
The following features cannot be linked to function keys (F1, F2, F3
and F4/ESC) and/or key and cannot therefore be changed by
the user. However, it is advisable to take note of them so that you
know which keys can be enabled/customized by the radio link pro-
vider. For more detailed information, contact the radio link provider.
6.2.a Microphone sensitivity
The sensitivity of the microphone is set so that the operator can talk
at a few centimeters from the microphone. However, if the environ-
ment or vehicle is particularly noise, the radio link provider may have
reduced the sensitivity to prevent the listener from hearing the noise
of the environment. In this case you will have to talk closer to the
microphone and/or with a higher tone to allow the listener to receive
your communication clearly.
6.2.b Adjusting the backlighting of keys
The backlighting of the keys on the front panel may have been ad-
justed as follows:
• Auto - Automatic backlighting. In this case the backlighting
switches on when you select a command and disables after ap-
proximately20seconds.
• Off - Backlighting off
• On - Backlighting always on
