10 ADVANCED FUNCTIONS
10.1 Channel scanning
This function is particularly helpful when multiple channels have been
programmed. It allows you to follow radio traffic, as well as to re-
spond to calls from different channels. When the radio picks up a
valid signal during scanning, it pauses on that channel and commu-
nication is heard on the speaker. When the signal ends, scanning
begins again automatically.
If CTCSS/DCS or selective calls have been previously programmed,
the device can be programmed to pause only at incoming signals
containing the appropriate signals.
10.1.a Activation of scanning

If you press the
PTT
transmission button during channel scanning,
the radio will pause on a predetermined channel, chosen during
the programming phase (this will be the priority channel or another
predefined one), and will begin transmission. When you release
