By placing your MOTOTRBO portable, you can (optionally) mute the receive
audio. This is very useful if you are, for example, in a meeting or in
an area where silence is needed. The radio can remain muted for a set period or until it is placed vertically again.
To enable this feature, you will need to upgrade to R2.7.0; purchase and activate the Mute Mode CfS licence and change some codeplug paramaters. On display model radios it is possible for the user to change some of these parameters.
