NOTE: Transmissions are inhibited on Channel
70 and any other channels that are configured as
'Receive-only' or 'Data-only'. If the PTT is pressed on
these channels the radio will emit a warning beep
and the PTT will be ignored.
Time-out Timer
The GX610 incorporates a time-out-timer to
automatically disable the transmitter if the PTT has
been pressed continuously for more than 5 minutes.
This is designed to prevent accidental jamming of
the channel frequency.
When your transmission time approaches 5 minutes,
a warning beep will be heard 10 seconds before
timeout occurs and the TX icon will flash. If you
release the PTT during this period, the time-out
timer will be reset and you can begin retransmitting
immediately.
However if the PTT is not released, a second warning
beep will occur signalling that the transmitter has
been disabled. Once the transmitter is disabled, the
TX icon will continue to flash even after you release
the PTT.
To reset the timer and re-enable the transmitter
Release the PTT and wait a further 10 seconds until
the TX icon stops flashing. The timer will then reset
and you can resume
transmitting.
CHANNEL 16
Channel 16 is the international Distress, Safety
and Calling channel. If you need to call for help in
an emergency or are seeking relevant information
from your local marine rescue base, use channel 16.
If the call is for an emergency you will probably be
asked to stay on channel 16 so others can provide
assistance but for less serious incidences you will
probably be transferred to a designated working
channel.
Press the
key at any time to go directly to
channel 16. The transmit power will be restored to
HI (2.5 Watts) and all other functions such as Scan,
Dual Watch and Triple Watch will be cancelled.
Press the
key again to return to the previously
selected channel. Alternatively, press the
keys to manually select a different channel.
