Call the marine operator and identify yourself by your vessel's name, The marine
operator will then ask you how you will pay for the call (telephone credit card,
collect, etc.) and then link your radio transmission to the telephone lines.
The marine telephone company managing the VHF channel you are using
may charge a link-up fee in addition to the cost of the call.

10.10 OPERATING ON CHANNELS 13 AND 67

Channel 13 is used at docks and bridges and by vessels maneuvering in port.
Messages on this channel must concern navigation only, such as meeting and
passing in restricted waters.
Channel 67 is used for navigational traffic between vessels.
By regulation, power is normally limited to 1 Watt on these channels. Your
radio is programmed to automatically reduce power to this limit on these chan-
nels. However, in certain situations it may be necessary to temporarily use a
higher power. See page 20 ( [ H/L ( NAV )] key) for means to temporarily override
the low-power limit on these two channels.
10.11 DUAL WATCH ( TO PRIORITY CHANNEL )
Dual watch allows the radio to monitor one channel and the assigned Priority
channel. By default the priority channel is set to 16, however the priority chan-
nel may be changed by referring to section "12.6 PRIORITY CHANNEL SET."
1. Adjust the SQL knob until the background noise disappears.
2. Select the channel you wish to dual watch to "Priority channel."
3. Press the [ DW ( IC )] key.
The display will scan between Priority channel and
the channel that was selected in step 2.
If a transmission is received on the channel selected
in step 2, the GX3000S will dual watch between the working channel and
the Priority channel.
4. To stop Dual Watch, press the [ DW ( IC )] key again.
