Scan for Conventional Systems
In conventional scanning, the scanner steps through each unlocked channel. If there is activity on the
channel, the scanner monitors activity until the transmission ends.
While monitoring the transmission, the first line alternates between the current system name and current
group name every 1 second. The second line displays the current channel name.
The Quick Keys for the current system and channel group blink. Furthermore, the attenuation setting,
modulation and CTCSS/DCS/P25 NAC data of current channel are displayed.
Even if the transmission ends, the scanner holds on the channel for the duration of the system delay time.
After the system delay time elapses, if there is no transmission the scanner resumes scanning.
*If CTCSS/DCS or P25 NAC is applied to a channel, the received signal must match for the scanner to hold
on the transmission. (Not for AM, WFM or FMB modulation.)

system hold time setting.
However, the scanner surely scans all unlocked channels at least 1 time, even if this takes longer than the
set time.
The scanner will advance to the next system once the scanner scans all unlocked channels and the system
hold time has elapsed.
Scan for Trunked Systems
In trunked scanning, the scanner holds on the control channel (C-Ch) and decodes the TGIDs as they
become active.
*If C-Ch Only is set to on at
Set C-Ch Only
for the site, trunking is performed using control channel data
only. A voice channel (V-Ch) does not have to be programmed into memory. (Motorola Systems only)
While scanning, press Function then [Scan / srch] to toggle between ID Scan and ID Search. You can also
change this mode through the Menu. (See:
ID Scan/Search
.)
ID Search :
If a TGID does not match any locked out TGID, the scanner goes to the V-Ch and monitors the transmission
until it ends.
