Motorola XPR 4380 ユーザーズマニュアル

There are two types of scans: 

Main Channel Scan (Manual): Your radio scans all the 
channels/groups in your scan list. On entering scan, your 

radio may – depending on the settings – automatically start 

on the last scanned “active” channel/group or on the channel 

where scan was initiated.

Auto Scan (Automatic): Your radio automatically starts 
scanning when you select a channel/group that has Auto 

Scan enabled.

NOTE: This feature is not applicable in Capacity Plus.

Procedure: 

Press the programmed Scan button.
OR
Use the Channel Rocker to select a channel with Auto Scan 
enabled.

When Scan is enabled, the yellow LED blinks and you hear 
a positive indicator tone. The scan icon is displayed.
OR
When Scan is disabled, the LED turns off and you hear a 
negative indicator tone. The scan icon turns off.

During scanning, your radio stops on a channel/group where 
activity is detected. The radio stays on that channel for a 
programmed time period known as “hang time”.

 

If the Channel Free Indication feature is enabled, you 

will hear a short alert tone the moment the transmitting radio 
releases the PTT button, indicating the channel is free for 
you to respond.

Press the PTT button during hang time. The green LED 
lights up.

Wait for the Talk Permit Tone to finish (if enabled) and speak 
clearly into the microphone.
OR

 Wait for the PTT Sidetone to finish (if enabled) and 

speak clearly into the microphone.

Release the PTT button to listen.

If you do not respond within the hang time, the radio returns 
to scanning other channels/groups.
