8 INSTRUCTION MANUAL GX400

To exit the Scan mode manually

Brieﬂy press the SCN key. ‘SCAN’ will disappear from the display.

NOTE: Excessive noise on a channel can cause the scanner to pause on that channel even if

there is no signal there. If this only happens on one channel, you may need to consider removing

that channel from the scan memory. If it happens on all channels, you should try increasing the

squelch setting.

PRIORITY CHANNELS (PR1/PR2)

There are two Priority channel memories labelled PR1 and PR2 that allow you to store channels

for instant recall.

To store a Priority channel, select the required channel using the

or keys, then press and

hold the required priority key (PR1 or PR2) to store the channel under the designated key.

To recall a Priority channel, brieﬂy press either PR1 or PR2. The radio will instantly jump to the

designated channel and the channel number will be displayed along with the associated ‘PR1’

or ‘PR2’ icon.

KEY LOCK FUNCTION

The Key Lock allows most of the keys to be locked to prevent accidental key presses from

changing the channel or the radio’s settings. While the keys are locked only the Volume,

Squelch and 88 button controls are available.

To lock the keys, press and hold the

key for 1 second. The icon is displayed and a

high beep is heard.

To unlock the keys, press and hold the

key again. The icon disappears and a low

beep is heard.

Channel 88

Channel 88 is the designated 27 MHz marine safety channel and in many areas is monitored by

coastal-watch and rescue organisations for emergency and safety purposes. When Channel 88 is

selected, ‘SAFETY’ is displayed on the LCD.

When making radio calls, you should make initial contact on Channel 88 then switch to another

channel to continue your conversation. This leaves Channel 88 free for other calls or emergencies.

Channel 88 key

Your GX400 has a dedicated Channel 88 key to allow instant access to Channel 88. Pressing

this key cancels all other functions such as Scan or Dual Watch and takes you straight to

Channel 88. When Channel 88 is selected using the 88 key, ‘SAFETY’ is displayed on the LCD

and the

or keys are disabled.

To return to normal channel operations brieﬂy press the 88 key again. ‘SAFETY’ will disappear

from the display, the radio will return to the previously selected channel and the

or keys

will be restored.

DUAL WATCH (MARINE MODE)

Dual Watch in the Marine mode allows your GX400 to monitor both Channel 88 and another

selected channel by quickly switching between them. Any signals received on Channel 88 take

precedence over signals on the selected channel.
