Monitor 

Press the MONI button to monitor any activity on the channel.  Wait for this activity to clear before 
transmitting. 

 

 

Channel Scan 

Channel scan is set to monitor desired activities on all channels in scan list

.

 When channel scan is 

enabled, the radio will automatically scan all channels in scan list until activity is detected on a channel.  
The scanning will then stop and the receive audio will be heard.

  

When scanning stops on an active channel, it will restart in the preset restart mode that is set by the 
dealer. Scan restart mode can be either Time operated scan or Carrier operated scan. 

Time Operated Scan 

If scanning stops on an active channel, and continues to listen for a preset period (the time is preset by 
the dealer), it will begin scanning other channels even if there is still activity on the channel. 

Carrier Operated Scan  

Scan will lock in on the busy channel until there is no activity.  
 

Channel Scan Operations 

1.  Press SCAN key 

Scan starts from the current channel and then scrolls all selected channels in sequence. 

2.  Press UP or DOWN key to change channel scan sequence. Press the UP key; radio skips the 

current channel and scans other selected channels in ascending order; press the DOWN key; 
radio skips the current channel and scans other selected channels in descending order. 

3.  Press SCAN key again, scan stops. 
4.  Adding or deleting a channel in/from the scan list. The dealer can add or delete a channel in/from 

the scan list. Only channels in the scan list can be scanned.  

 

 

Priority Channel Scan

 

If your dealer has set a priority channel, when radio scans non-priority channels, it will periodically 
sample the priority channel

.

 If desired activity is detected on the priority channel, it will switch to the 

priority channel for communications. 
 

 

Scan Revert Channel 

The scan revert channel feature allows you to transmit on the proper channel while initiating a call 
during channel scan. Press [PTT] button, radio stops scanning and transmits on the revert channel. 
This feature is set by the dealer. 

 

 

Selectable CTCSS/CDCSS  

CTCSS/CDCSS feature is used to avoid receiving unwanted signals on the same channel. When 
CTCSS/CDCSS is enabled, the radio only allows audio with the same CTCSS/CDCSS code to 
activate the speaker. If CTCSS/CDCSS is disabled, the radio will hear all calls on the same channel.  
When the dealer allows CTCSS/CDCSS to be selectable by the end user, the operations are as 
follows:
