Table 6-1 (Continued)

Boaters should normally use channels listed as Non-Commercial.

NOTE

1.The letter “A” following a channel number indicates simplex use of the ship station transmit side of an international duplex channel. Operations are different from that of international operations on that channel.

2.Channels 13 should be used to contact a ship when there is danger of collision. All ships of length 20 meters or greater are required to guard VHF channel 13, in addition to VHF channel 16, when operating within U.S. territorial waters.

3.Channel 16 is used for calling other stations or for distress alerting.

4.Channel 13 and 67 are 1 Watt initially.

User can override to high power (25 Watts) via front panel controls.

5.The transmitter is automatically disabled when channels 1, 2, 3 and 4 are selected.

6.Channels 75 and 76 are receive-only. Transmission on these channels has been disabled as a precaution to avoid harmful interference to channel 16.

CAUTION

Operation on channels not designated for use by your classification of craft or on International Channels within the US territorial waters is a violation of FCC Rules and Regulations and way result in severe penalties.
