5.19 CLONING
The HX370S includes a convenient “Clone” feature, which allows the memory
and configuration data from one transceiver to be transferred to another
HX370S.
1. Turn both radios off.
2. Connect the (optional) CT-32 Clone Cable between the MIC/SP jacks of
the two transceivers.
3. Hold down the PRESET key and then turn on the
transceiver. Do this for both transceivers (the order
of switching the radios on does not matter); “
CLn CLnCLn CLn
CLn” will
appear on the display on both transceivers.
4. On the Destination transceiver, press the PRESET
key (“
Cr CrCr Cr
Cr” will appear on the LCD).
5. Press the 16/9 key on the Source transceiver; “
CS CSCS CS

will displayed. Check your cable connections and
battery voltage, and try again.
7. If the data transfer is successful, the Destination transceiver will return
to normal operation; Turn both transceivers off and disconnect the Clone
cable. You can then turn the transceivers back on, and begin normal
operation.

8. CHANNEL ASSIGNMENTS
Tables on the following columns list the VHF Marine Channel assignments
for U.S.A. and International use. Below are listed some data about the charts.
1. VTS. Where indicated, these channels are part of the U.S. Coast Guard’s
Vessel Traffic System.
2. Alpha channel numbers, that is, channel numbers followed by the letter
A (such as Channel 07A) are simplex channels on the U.S.A. or Cana-
dian channel assignments whose counterparts in the International as-
signments are duplex channels. International channels do not use “Al-
pha” numbers. If you call the Coast Guard on Channel 16, they will some-
times ask you to “go to channel 22 Alpha.” This is a channel assigned
to U.S.A, and Canadian Coast Guards for handling distress and other
calls. If your radio is set for International operation you will go to Chan-
nel 22 instead of 22A, and will not be able to communicate with the
Coast Guard. To use Channel 22A, your radio must be set for USA or
Canada operation, usually by a U/I/C (USA/International/Canada) con-
trol or combination of controls. Channel 22 (without an “A” is an Interna-
tional duplex channel for port operations. Some radios indicate an “A”
adjacent to the alpha channels on the display; on others “Alpha” is not
indicated but the proper channel is selected based on the U/I/C setting.
3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge
operators on intercoastal waterways and rivers. It is also used by marine
vessels in the vicinity of these bridges for navigation and for communi-
cating with the bridge operators. Note that a limit of 1 Watt is specified
for these channels. See page 23 for additional information.
4. The S/D column on the chart indicates either S (simplex) or D (duplex).
Simplex means transmitting and receiving on the same frequency. Only
one party at a time can talk, unlike a telephone. Be sure to say “over”
and release your microphone push-to-talk switch at the end of each trans-
mission. Duplex operation involves the use of one frequency for trans-
mitting and a separate frequency for receiving. On channels specified

as duplex on the charts, correct mode of operation is established auto-
matically by your radio when you select a channel; you cannot change
the mode. And you still must release the push-to-talk switch after each
transmission in order to listen to the radio.
5. Channels normally used by recreational boaters are those that include
the term “non-commercial” in the Channel Use column of the chart. Some
of these are shared with other users and some are used only in certain
geographic regions.
6. Marine vessels equipped with VHF radios are required to monitor
Channel 16.
