• In scan mode the display shows both frequencies.
o The active frequency is shown on the top line and the
preset frequency on the bottom line.
• The SCAN symbol in the display shows that scan function is
started.
In all frequency selection modes:
• A long push (>2 s) of "↕/SCN" key starts the scan function and
changes to standard mode, if started from channel or direct
tune mode.
• A short push on the "MDE" key or a long push (>2 s) on
"↕/SCN" key stops the scan function.
The device stays in standard mode.
• The arrow symbol "►” in front of the frequency shows that this
frequency is audible.
If both the active and preset frequency find a signal at the same
time, the active frequency (top) has priority.
• The preset frequency is shown inverted and blinks.
• An audio notification "beep" tone is audible and the preset
frequency blinks to show that there is a RX signal on the preset
frequency (if enabled in the configuration setup*).

active frequency, the transceiver automatically changes to the

the monitored frequency is currently audible.
