7.7 CHANNEL 9
Channel 9 is used as a hailing channel for initial, non-emergency contacts
with other vessels. Hold down the [16/9] key for 1 second to select channel
9. You should change to a working channel, after contact is established (so
as to keep the hailing channel clear for other users).
7.8 OPERATING ON USA OR CANADIAN 13, OR USA CHANNEL 67
USA and Canadian Channel 13, USA 67 are used at docks, bridges and for
maneuvering in port. Messages on this channel must concern navigation
only, such as meeting and passing in restricted waters. In emergencies and
when approaching blind river bends, high power is allowed. Pressing the
[H/L] key will change the power output from 1 Watt (
) to 5 Watts ( ); if
pressed again, 2.5 Watts ( ) will be selected. When the PTT switch is re-
leased, the transceiver will revert to Low power. Press the [H/L] key again if
you need High power on a subsequent transmission.
7.9 OPERATING ON USA CHANNEL 67
USA Channel 67 is used for navigational bridge-to-bridge traffic between
ships. This channel has been allocated for temporary high power transmis-
sion if communication is not able to be established on one watt.
Select Channel 67, then press the [H/L] key to set the transmitter output to
either High or Medium power. When the PTT switch is released, the trans-
ceiver will revert to low power.
7.10 SIMPLEX/DUPLEX CHANNEL USE
All Marine channels are factory-programmed in accordance with FCC (USA),
Industry Canada and International regulations. The mode of operation can-
not be altered from simplex to duplex or vice-versa. Simplex (ship to ship) or
duplex (marine operator) mode is automatically activated, depending on the
channel and whether the USA, International or Canadian operating band is
selected.
