3.5 OPERATING ON CHANNEL 13
Channel 13 is 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
key will change the power output from
Low Power (1 Watt) to High (5 Watts). When you change from this channel
then return to it, low power will be automatically selected.
3.6 OPERATING ON CHANNEL 67
When channel 67 is used for navigational bridge-to-bridge traffic between ships,
High power may be used temporarily (in the USA band) by pressing the
key. When the
PTT

power.
3.7 SIMPLEX/DUPLEX CHANNEL USE

tions on use of simplex and duplex channels.

All channels are factory-programmed in accordance with FCC, Industry
Canada, and International regulations. The mode of operation cannot
