amples for USA use are Channels 24, 25, 26, 27, 28, 84, 85, 86, and 87. 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.

8.10 OPERATING ON CHANNELS 13 AND 67

Channel 13 is used at docks and bridges and by vessels manoeuvering 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 channels. 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.

8.11 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 “10.6 PRIORITY CHANNEL SET.”

If a transmission is received on the channel selected

in step 2, the GX3000E will dual watch between the working channel and the Priority channel.

4. To stop Dual Watch, press the [DW(IC)] key again.
