Disabling Automatic Channel Switching

If you are involved in a bridge-to-bridge call, you may not want the radio to automatically switch channels when it receives a DSC call. 

In cases like this, you can disable automatic channel switching. If you receive an individual call, the radio will respond with an 

unattended code, just as if the radio were in Standby. 
1.  Press and hold 

CALL-MENU

 to display the normal menu. 

2.  Select 

Setup

 and then

 Auto CH SW

3.  Choose 

Off

 and press 

ENT-1W/25W

. The radio will not automatically switch channels until you reactivate this feature. 

NOTE: Use this feature with caution. Deactivating automatic switching and then forgetting it can make it hard for you to receive 

DSC calls. 

If you have unread incoming DSC calls, the radio displays a message icon ( 

 ). You will be able to review who has called. The 

radio displays the last 10 distress calls and the last 20 non-distress calls it received (see the receive log on page 17). 

Renaming Channels 

If you discover that a marine radio channel has a different common name in your local area, you can change the name of that 

channel to make it easier for you to use (see the channel lists beginning on page 30 for the default channel names). To rename a 

channel, follow the steps below: 
1.  Display the normal menu and choose the 

Setup

 sub-menu. 

2.  Select 

Channel Name

. The screen displays the list of channels. 

3.  Use 

CHANNEL UP

 and 

CHANNEL DOWN

 to choose the channel you want to change and press 

ENT-1W/25W

4.  Select 

Rename

 to enter a new name for this channel. The radio prompts you to enter a new name for this channel. Each name 

can be up to 12 characters. Use 

CHANNEL UP

 and 

CHANNEL DOWN

  to change the first character. 

5.  When the first character is correct, press 

ENT-1W/25W

. The cursor moves to the next character. Enter the remaining 11 

characters of the name. If the name is shorter than 12 characters, press and hold 

ENT-1W/25W

 to complete the name entry. 

If you make a mistake while entering a number, press 

CLR-SCAN

 to erase the wrong number and the cursor is moved to the 

left digit. 

6.  When you finish entering the name, the radio displays the new channel name and asks you to confirm. To save this new chan-

nel name, select 

Yes

; to cancel the change, select 

No

. The radio returns to the channel list. 

7.  To restore a channel back to its original name, select the channel and choose 

Default

8.  When you are satisfied with the channel list, select 

Exit

 to close the menu screen.
