transmitting. The bar graph above this icon shows 1 bar for low power and 6 bars for high
power.

Allows selection of both Digital and Analogue Squelch settings. The squelch is like a filter
where it can be changed to listen to all traffic (monitor), or only your system traffic (normal),
or only your talkgroup or calls to your identity.
6.10 T
ALKAROUND
On a repeater channel only, this function button allows the radio to transmit on the base
station’s output channel, so the user can talk directly to other mobiles on the channel, while
the repeater is out of service or out of range.
When the key is pressed again (or the Channel is changed) the mobile’s transmitter channel
reverts to its normal setting.
Talkaround mode is indicating to the user by a double beep at the start of each PTT.
