with other vessels. Hold down the [

9. You should change to a working channel, after contact is established (so
as to keep the hailing channel clear for other users).

revert to Low power. Press the [ H/L ] key again if you need High power on a
subsequent transmission.

ships. This channel has been allocated for temporary high power transmis-
sion if communication is not able to be established on one watt.

either High or Medium power. When the PTT switch is released, the trans-

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.
