Scanning channels
The RS90 can automatically monitor more than one channel at the
same time. It scans a selected range of channels, and when a valid
signal is received, the radio stops scanning and remains on that
channel so that you can hear the communication. However, if the
signal from the channel ceases for more than 5 seconds, the scan
automatically restarts.
Four scan modes are provided:
• All scan
Scans all available channels in sequence, but also checks the priority
channel every 2 seconds.
• Dual watch scan
Scans the selected channel and channel 16.
• 3CH scan
Scans your three favourite channels and the priority channel.
• Tri watch scan (US models only)
Scans the current channel, channel 16 and channel 9.
ALL SCAN mode
Hold down [SCAN] for about 3 seconds to start ALL SCAN mode.
The radio displays the SCAN icon and “ALL SCAN.” You will see the
channel numbers changing.
• If you hear a communication of interest, press [SCAN] or [PTT] to
stop at the currently scanned channel.
• Press [X] to quit scan mode and return to the previously selected
channel.
¼ Notes
• Scan is not allowed in some EU countries.
• If TONE ALERT or SAME is enabled (US models only), the weather
channel is also scanned.
• If you are in Navigation mode and want to scan the DSC channels
while staying in that mode, just hold down SCAN. For information
on Navigation mode, see “Navigating to a waypoint” on page 39.
