HX320E Marine VHF.
NOTE:
visiting the STANDARD HORIZON website from time to time may be bene-
cial. When new products are released, information will appear on the website.
4. ABOUT THIS RADIO
4.1 ABOUT THE VHF MARINE BAND
The radio frequencies used in the VHF marine band lie between 156 and 158
MHz with NOAA Weather stations available between 161 and 163 MHz. The
marine VHF band provides communications over distances that are essentially
“Line of sight” Actual transmission range depends much more on antenna type,
gain and height than on the power output of the transmitter. On a xed mount
25 W radio transmission expected distances can be greater than 15 miles, for
a portable 5 W radio transmission the expected distance can be greater than
5 miles in “Line of sight”.
The user of a Marine VHF radio is subject to severe nes if the radio is used on
land. The reasoning for this is you may be near an inland waterway, or propaga-
tion anomalies may cause your transmission to be heard in a waterway. If this
occurs, depending upon the marine VHF channel on which you are transmitting,
you could interfere with a search and rescue case, or contribute to a collision
between passing ships. For VHF Marine channel assignments refer to section
“13. VHF MARINE CHANNEL ASSIGNMENTS”.
WARNING
This radio is capable of transmitting on Marine VHF radio frequencies.
The FCC allows the use of VHF Marine band on water areas only. Use of
the VHF Marine band when on land is not permitted. If persons use the
VHF Marine Band on land and interfere with other communications, the
FCC will be notied and search for the interference. Responsible parties
found to be transmitting on the VHF Marine Band on land could be ned
up to $10,000 for the rst oense.
4.2 ABOUT WATER PROTECTION
The HX320E is only submersible* when the MIC/SP jack and the CHG jack
are securely covered with the rubber caps.
*(IPX7 Specication for submersibility: 3 ft. (1 m) for 30 minutes)

Page 5
4.3 DISTRESS AND HAILING (CHANNEL 16)
Channel 16 is designated as the Hail and Distress Channel. An emergency may
be dened as a threat to life or property. In such instances, be sure the transceiver
is turned ON, and set to “Channel 16”. Then use the following procedure:
1. Press the PTT (Push-To-Talk) switch and say “Mayday, Mayday, Mayday.
This is _____, _____, _____” (your vessel’s name).
2. Then repeat once: “Mayday, _____” (your vessel’s name).
3. Now report your position in latitude/longitude, or by giving a true or magnetic
bearing (state which) to a well-known landmark such as a navigation aid
or geographic feature such as an island or harbor entry.
4. Explain the nature of your distress (sinking, collision, aground, re, heart
attack, life-threatening injury, etc.).
5. State the kind of assistance you desire (pumps, medical aid, etc.).
6. Report the number of persons aboard and condition of any injured.
7. Estimate the present seaworthiness and condition of your vessel.
8. Give your vessel’s description: length, design (power or sail), color and other
distinguishing marks. The total transmission should not exceed 1 minute.
9. End the message by saying “OVER”. Release the PTT switch and listen.
10. If there is no answer, repeat the above procedure. If there is still no response,
try another channel.
4.4 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)
Channel 16 may be used for initial contact (hailing) with another vessel.
However, its most important use is for emergency messages. This channel
must be monitored at all times except when actually using another channel.
It is monitored by the U.S. and Canadian Coast Guards and by other vessels.
Use of channel 16 for hailing must be limited to initial contact only. Calling should
not exceed 30 seconds, but may be repeated 3 times at 2-minute intervals. In
areas of heavy radio trac, congestion on channel 16 resulting from its use as
a hailing channel can be reduced signicantly in U.S. waters by using Channel
9 as the initial contact (hailing) channel for non-emergency communications.
Here, also, calling time should not exceed 30 seconds but may be repeated 3
times at 2-minute intervals.
Prior to making contact with another vessel, refer to the channel charts in this
manual, and select an appropriate channel for communications after initial
contact. For example, Channels 68 and 69 of the U.S. VHF Charts are some of
the channels available to non-commercial (recreational) boaters. Monitor your
desired channel in advance to make sure you will not be interrupting other trac,
and then go back to either channel 16 or 9 for your initial contact.

Page 6
When the hailing channel (16 or 9) is clear, state the name of the other vessel
you wish to call and then “this is” followed by the name of your vessel and
your Station License (Call Sign). When the other vessel returns your call, im-
mediately request another channel by saying “go to”, the number of the other
channel, and “over”. Then switch to the new channel. When the new channel
is not busy, call the other vessel.
After a transmission, say “over”, and release the PTT (Push-To-Talk) switch.
When all communication with the other vessel is completed, end the last
transmission by stating your Call Sign and the word “out”. Note that it is not
necessary to state your Call Sign with each transmission, only at the beginning
and end of the contact.
Remember to return to Channel 16 when not using another channel. Some
radios automatically monitor Channel 16 even when set to other channels or
when scanning.
4.5 BRIDGE CHANNELS 13 AND 67
Channel 13 is used at docks, 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 trac 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 14 for means to temporarily override the low-power limit on
these two channels.
4.6 SIMPLEX/DUPLEX CHANNEL USE
Refer to the section “13. VHF MARINE CHANNEL ASSIGNMENTS” for instruc-
tions on use of simplex and duplex channels.
NOTE
All channels are factory-programmed in accordance with FCC (USA),
ISED (Canada)and International regulations. The mode of operation
cannot be altered from simplex to duplex or vice-versa. Simplex (ship to
ship)or duplex (marine operator)mode is automatically activated, de-
pending on the channel and whether the USA, International or Canadian
operating band is selected.

2. Press and hold the [SQL] switch until the
“” indicator appears on the display. This
is the “squelch o” state.
2. Press the [VOL-] or [VOL+] key until noise
or audio from the speaker is heard at a
comfortable level.
3. Press the [SQL] switch to resume normal (quiet) monitoring.
5. Press the [p] or [q] key to select the desired channel. Refer to the channel
chart on page 46 for available channels.
6. When a signal is received, adjust the volume to the desired listening level.
The “ ” indicator on the LCD is displayed indicating that the channel
is being used or the radio is not squelched.
8.4 TRANSMISSION
1. Setup the transceiver as described in the “8.3 RECEPTION” discussion
above.
2. Before transmitting, monitor the channel and make sure it is clear.
THIS IS AN FCC REQUIREMENT!

8.4.1 TRANSMIT POWER
The TX output power of the HX320E is set to high level (6 W※) in factory default,
and the “HI” indicator is displayed on the top part of the screen.
To change the TX output power:
1. Press one of the soft keys.
2. Press the [◄] or [►] key repeatedly, until [HI],
[MD], or [LO] is displayed above a soft key at
the bottom of the LCD.
3. Press the [HI], [MD], or [LO] soft key to switch

8.4.2 TRANSMIT TIME - OUT TIMER (TOT)
While the PTT switch is held down, transmission time is limited to 5 minutes.
This prevents prolonged (unintentional) transmissions. About 10 seconds before
automatic transmitter shutdown, a warning beep will sound from the speaker.
The transceiver automatically switches to receive mode, even if the PTT switch
continues to be held down. The PTT switch must rst be released, then wait
10 seconds before transmission may be started again. This Time-Out-Timer
(TOT) prevents a continuous transmission that would result from an accidentally
stuck PTT switch.
WATER ENABLED LIGHT
When the HX320E comes in contact with water a white light will blink to
assist retrieving it in low light conditions. The light will automatically turn
o in about 15 seconds when it is removed from water.
The HX320E has a menu selection to enable and disable. Refer to SET-
UP Mode Item “STROBE LED (Water Hazard)” on page 39 for details.
