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

OPERATION ON THE AUSTRALIAN MARINE BAND
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 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.
Safety channel key
Your GX400 has a dedicated Safety channel 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 key, ‘SAFETY’ is displayed on the LCD.
To return to normal channel operations briefly press the key again. ‘SAFETY’ will disappear
from the display, the radio will return to the previously selected channel. Alternatively press the
or keys to select a different channel.
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.
