Scan On/Off
You can enter scan mode through any of the following two methods:
1. Key operation
Press the programmed
Scan key to enter scan mode, provided that there’re
no less than 2 members in the scan list. Press Scan key again or power off to
exit.
2. Auto
If Auto Scan is enabled for a channel, the radio will automatically enter scan
mode when it is switched to this channel. When it is switched to other channels
or powers off, the radio will exit from scan mode.
Talk Back
This option defines whether users can talk back on the channel where
scanning pauses. When the option is checked, users can do so.
If the scanning does not pause on any channel, users may talk back on the
predefined channel.
Priority Channel Scan
This function enables users to scan the most frequently used channel so
that messages will not be missed. The priority channel is programmed by the
dealer via programming software. Contact your dealer for details.
Note: Even though the radio remains on a non-priority channel, activities
on the priority channel are still under monitoring. The radio will switch to the
priority channel once any activity is detected.
Available Keys in Scan Mode
PTT key, Volume Adjust keys [+] / [-], and 4 programmable keys of Squelch
Off, Squelch Off Momentary, Monitor and Monitor Momentary.
Busy Channel Lockout (BCL)
This function can help avoid interference between radios operating on the
same channel. When the channel is already in use, the radio will sound a
continuous warning tone and return to Receive mode upon
PTT press. To
cancel the tone, release the PTT key.
