NOTE:
Prior to using Triple Watch ensure you have
programmed your second priority channel.
To use the Triple Watch Function
1. Press the 
or
keys to select your preferred
working channel.
2. Press and hold the
key to activate Triple Watch.
‘TRIW’ will be displayed and the channel numbers will 
quickly switch between 16, the second priority channel 
and the selected channel.
If a signal is received on either the selected channel or 
the second priority channel, the Triple Watch will pause to 
allow the signal to be heard but will continue to monitor 
channel 16 every 2 seconds resulting in short breaks in 
the conversation. Once the signal has gone, Triple Watch 
continues.
If a signal appears on channel 16 it will take priority over any 
signals on the other two channels. 
To cancel Triple Watch, briefly press the
key.
TIME OUT TIMER
The radio has a built-in time out timer that automatically 
limits transmissions to a maximum of 5 minutes of 
continuous operation. This feature is required to prevent 
accidental blocking of the frequency should your PTT become 
jammed or be otherwise pressed accidentally.
When the time out timer activates, the transmission will stop, 
and the radio will return to receive mode. Normal operation 
will be restored once the PTT is released.
ATIS OPERATION
ATIS stands for Automatic Transmitter Identification System. 
ATIS is used to identify a ship or vessel that has made a radio 
transmission. The identity of the vessel is sent digitally each 
time the radio operator releases the PTT after transmitting. 
ATIS is generally used in the inland waterways of Europe 
and is only available when the International channel set is 
selected.
The use of ATIS requires a unique 9 digit Maritime Mobile 
Service Identity or MMSI (note that the ATIS MMSI is 
completely separate to the MMSI required for the DSC 
functionality included in DSC compatible radios). Radio 
operators in Europe who require the ATIS function should 
obtain their unique ATIS MMSI from their local Maritime 
Authority.
IMPORTANT:
Once the ATIS ID has been programmed
into the radio, the ATIS function is enabled and becomes a 
permanent part of the radio’s operation. It cannot be disabled 
by the user.
Programming the ATIS ID
1. Switch the radio Off.
2. Hold the
key while switching the radio On. The
display will show ‘1 –‘ where the left character shows the 
position of the ATIS digit within the ATIS ID (e.g. position 1 
of 9) and the right flashing character shows the currently 
selected value of the ATIS ID digit at that position.
