SCAN
Scan is the function to check whether the transceiver receives a call from other transceivers.
The transceiver sequentially checks for availability of a signal on each channel, and the transceiver receives a signal on
the channel where the signal is detected.
Note
Refer to 8.9 Site Roaming on page 76
16.1 Starting the Scan
Pressing the Scan key causes the transceiver to start the Scan.
For Portable, the LED blinks green during the scan.
For Mobile, "Sc" appears on the LED display during the scan.
The transceiver scans all channels to be scanned in the zone where the transceiver starts the scan.
Channels to be scanned are the channels where Scan Add is enabled by using KPG-169D/ KPG-170D/ KPG-175D. The
channels configured to be scanned using the Scan Delete/Add key will also be scanned (Mobile only).
One of the following conditions must be satisfied to start the scan. An Error tone sounds from the transceiver when no
condition is satisfied.
• Two or more channels to be scanned must coexist in the selected zone.
• One channel to be scanned must exist in the selected zone and the Priority Channel must exist in the zone or
another zone.
The Priority Channel will be scanned even if the Priority Channel exists in another zone. However, the configuration for
Zone Type (Analog or NXDN) of the zone where the Priority Channel exists must be the same as the configuration of the
zone where the transceiver starts the scan.
Configuration using KPG-169D/ KPG-170D/ KPG-175D
• Configuring the Scan Add to be enabled or disabled for each channel (
Channel Edit > Page 1)
• Assigning functions to the PF keys (
16.2 Scanning the Specific Channel Preferentially (Priority Scan)
Priority Scan can be used to scan the high priority channel regardless of the scan configuration for each channel.
If Priority Channel is configured, the Priority Channel is monitored by using Lookback even when the scan pauses on a
normal channel (a channel other than the Priority Channel).

Scan Start
The transceiver scans the Priority Channel at the intervals configured for Lookback Time A and Lookback Time B. (Refer
to Lookback on page 177)
Priority Channel can be configured separately for analog channels and NXDN digital channels by using KPG-169D/
KPG-170D/ KPG-175D. Also, Priority Scan type can be configured for the Priority Channel as below:
