RF EXPOSURE SAFETY STATEMENT
SAFETY INFORMATION
Your wireless handheld portable transceiver contains a low power trans-
mitter. When the Push-to-Talk (PTT) button is pushed, the transceiver
sends out radio frequency (RF) signals. In August 1996, the Federal
Communications Commission adopted RF exposure guidelines with
safety levels for hand-held wireless devices.
This device is authorized to operate at a duty factor not to exceed 50%
(this corresponds to 50% transmission time and 50% reception time).
WARNING: To maintain compliance with the FCC’s RF exposure guide-
lines, this transmitter and its antenna must maintain a separation dis-
tance of at least 1 inch (2.5 centimeters) from your face. Speak in a
normal voice, with the antenna pointed up and away from the face at the
required separation distance.
Use only the supplied antenna. Unauthorized antennas, modifications,
or attachments could damage the transmitter, and may violate FCC regu-
lations.

3. ABOUT THIS RADIO
3.1 ABOUT THE VHF MARINE BAND
WARNING
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 dis-
tances that are essentially “Line of sight” Actual transmission range de-
pends much more on antenna type, gain and height than on the power
output of the transmitter. On a fixed 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 fines if the radio is
used on land. The reasoning for this is you may be near an inland water-
way, or propagation 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 page 32 section 9.
HX280SPage 10
4. GETTING STARTED
4.1 RADIO CARE
CAUTION
Before following the instructions below, insure the battery pack is in place
and firmly tightened. Care must be taken if the radio was dropped and a
close inspection may be needed to insure the radio case and gaskets
are in adequate condition.
Clean the radio with fresh water after exposure to salt water by rinsing the
radio under a sink faucet or by dunking the radio in a bucket of fresh water.
After washing, use a soft cloth and thoroughly dry all parts of the radio. This is
to keep the rubber switches and speaker grill clean and in top operating condi-
tion.
4.2 BATTERIES AND CHARGERS
If the radio has never been used, or its charge is depleted, it may be charged
by connecting the CD-46 Charger Cradle with the NC-90B battery charger, as
shown in the illustration. If 12V DC power is available, the optional E-DC-19A
DC Cable with 12 V Cigarette Lighter Plug or the optional E-DC-6 DC Cable
may be used for charging the battery. The NC-90B, E-DC-19A, and E-DC-6
will charge a completely discharged FNB-V105LI battery pack in about 6 hours.
The FNB-V105LI is a high performance Li-Ion battery providing high capacity
in a compact package.
CAUTION
To avoid risk of explosion and injury, FNB-V105LI battery pack should
only be removed, charged or recharged in non-hazardous environments.
4.2.1 BATTERY SAFETY
Battery packs for your transceiver contain Li-Ion batteries. This type of battery
stores a charge powerful enough to be dangerous if misused or abused, espe-
cially when removed from the transceiver. Please observe the following pre-
cautions:
DO NOT SHORT BATTERY PACK TERMINALS: Shorting the terminals that
power the transceiver can cause sparks, severe overheating, burns, and bat-
tery cell damage. If the short is of sufficient duration, it is possible to melt
battery components. Do not place a loose battery pack on or near metal sur-
faces or objects such as paper clips, keys, tools, etc. When the battery pack is
installed on the transceiver, the terminals that transfer current to the trans-
ceiver are not exposed. The terminals that are exposed on the battery pack
Page 11HX280S
when it is mounted on the transceiver are charging terminals only and do not
constitute a hazard.
DO NOT INCINERATE: Do not dispose of any battery in a fire or incinerator.
The heat of fire may cause battery cells to explode and/or release dangerous
gases.
Battery Maintenance
For safe and proper battery use, please observe the following:
yBattery packs should be charged only in non-hazardous environments;
yUse only STANDARD HORIZON-approved batteries;
yUse only a STANDARD HORIZON approved charger. The use of any
other charger may cause permanent damage to the battery.
yFollow charging instructions provided with the chargers.
yKeep the battery contacts clean.
Battery Storage
Store the batteries in a cool place to maximize storage life. Since batteries are
subject to self-discharge, avoid high storage temperatures that cause large
self-discharge rates. After extended storage, a full recharge is recommended.
Battery Recycling
DO NOT PLACE USED BATTERIES IN YOUR REGULAR TRASH!
LI-ION BATTERIES MUST BE COLLECTED, RECYCLED OR DISPOSED
OF IN AN ENVIRONMENTALLY SOUND MANNER.
The incineration, land filling or mixing of Li-Ion batteries with the municipal
solid waste stream is PROHIBITED BY LAW in most areas.
Return batteries to an approved Li-Ion battery recycler. This may be where
you purchased the battery.
Contact your local waste management officials for other information regarding
the environmentally sound collection, recycling and disposal of Li-Ion batter-
ies.

3. To exit from the weather channel mode, press the [WX] key. The trans-
ceiver will revert to the channel you were using prior to switching to the
weather channel mode.
6.8.1 NOAA WEATHER ALERT
In the event of extreme weather disturbances such as storms and hurricanes,
NOAA sends a “weather alert” consisting of a 1050 Hz tone, followed by weather
reports on the weather channels.
When a “weather alert” is received on a weather channel,
the transceiver emits a beep tone and “ ” icon is
shown on the display. Press the [WX] key to stop the beep
tone and listen to the weather reports.
NOTE
Options for the Weather Alert feature are available, refer to Menu Mode
Item “ALt (WX ALERT)” on page 29 for details.
6.8.2 NOAA WEATHER ALERT TESTING
In the event of a major storm or other appreciable weather condition requiring
vessels at sea (or other bodies of water) to be notified, the NOAA (National
Oceanographic and Atmospheric Administration) broadcasts a 1050 Hz tone
that some VHF radios, including your HX280S, can detect for “Weather Alarm”
purposes (refer to section “6.8.1 NOAA WEATHER ALERT” for a discussion
of how to use this feature). The 1050 Hz tone, when detected, will produce a
loud beep in the speaker of the HX280S, to signal that a Weather Alert Broad-
cast is being received.
In order to test this system, NOAA broadcasts the 1050 Hz tone every Wednes-
day sometime between 11 AM and 1 PM local time. You may use this opportu-
nity to test your HX280S periodically to confirm that the Weather Alert feature
is working, or for training crew members on how to configure the HX280S to
receive the NOAA Weather Alerts.

will disappear after one second.
Page 23HX280S
6.10 SCANNING
The HX280S allows the user to select the scan type from “Memory Scan” or
“Priority Scan”. “Memory Scan” scans the channels that were programmed
into memory. “Priority Scan” scans the channels that were programmed into
memory with the priority channel (Channel 16). When an incoming signal is
detected on one of the channels during scan, the radio will pause on that
channel, allowing you to listen to the incoming transmission.
6.10.1 SELECTING THE SCAN TYPE
1. Turn the transceiver off by rotating the VOL knob fully counter-clockwise.
2. Hold down the [SQL] key, and then turn on the transceiver while still hold-
ing down the [SQL] key.
3. “SEtSEt
SEtSEt

PS (Priority Scan)” or
“MSMS
MSMS
MS (Memory Scan)”. The factory default is “PSPS
PSPS
PS
(Priority Scan)”.
6. After completing your selection, turn the trans-
ceiver off and on by rotating the VOL knob.
6.10.2 MEMORY SCANNING (M-SCAN)
1. Select the desired channel to be included in the scan memory using the
[T] or [S] key.
2. Press the [MEM] key to store the channel into the
transceiver’s scan memory. “MEM” will be displayed on
the LCD.
3. Repeat steps 1 and 2 for all the channels to be scanned.
4. To delete a channel from the transceiver’s scan memory, select the memo-
rized channel, then press the [MEM] key to delete the channel from scan
memory.
5. All channels programmed remain in the transceiver’s scan memory even if
the power is turned off.
6. Adjust the SQL level until background noise is eliminated by pressing the
[SQL] key followed by the [T] / [S] key.
7. To start scanning, press the [SCAN(DW)] key. The scan
proceeds from the lowest to the highest programmed
channel and stops scanning when a transmission is re-
ceived. Scanning will resume when the incoming signal
disappears at the end of the transmission. The “MEM” and “SCN” icon will
HX280SPage 24
appear at the left of the channel number on the display during scanning.
8. To stop the scan, press the [SCAN(DW)] key.
6.10.3 PRIORITY SCANNING (P-SCAN)
1. Select the desired channel to be included in the scan memory using the
[T] or [S] key.
2. Press the [MEM] key to store the channel into the
transceiver’s scan memory. “MEM” will be displayed on
the LCD.
3. Repeat steps 1 and 2 for all the channels to be scanned.
4. To delete a channel from the transceiver’s scan memory, select the memo-
rized channel, then press the [MEM] key to delete the channel from scan
memory.
5. All channels programmed remain in the transceiver’s scan memory even if
the power is turned off.
6. Adjust the Squelch Level until background noise is eliminated by pressing
the [SQL] key followed by the [T] / [S] key.
7. To start scanning, press the [SCAN(DW)] key. A “SCN” icon and blinking
“P” and “MEM” icons will appears at the left of the channel number on the
display during scanning. The scan proceeds between
the memorized channels and the Priority Channel (Chan-
nel 16).
As an example of priority scanning, let us say that ma-
rine channels “06”, “07”, and “08” are memorized in the transceiver’s scan
memory. Priority scanning will proceed in the following sequence:
[CH06] Æ (CH16)Ú Æ [CH07] Æ (CH16)Ú Æ
[CH08] Æ (CH16)Ú Æ [CH06] Æ (CH16)Ú Æ [CH07] .....
Ú: Priority Channel
4. Even when the transceiver stops and listens to the signal of a programmed
channel, the transceiver will “dual watch” between this channel and the
priority channel. This allows the radio to be able to receive calls on chan-
nel 16 (priority channel) even when the radio is receiving on another chan-
nel.
5. To stop the Priority Scanning, press the [SCAN(DW)] key.
Page 25HX280S
6.11 DUAL WATCH
The Dual Watch feature allows the radio watch the Priority Channel “Channel
16” and one other channel.
1. Select the desired channel using the [T] or [S] key.
2. Press and hold the [SCAN(DW)] key for two seconds to
activate the Dual Watch feature. A “ ” icon will ap-
pear on the upper left of the display when the Dual Watch
feature is activated.
3. When a transmission is received on the “Priority Channel”, the radio re-
ceives the “Priority Channel” until the incoming signal disappears.
4. When the radio receives a transmission on the working channel, the radio
will dual watch between the working channel and Channel 16.
5. The Dual Watch feature will resume when the incoming signal disappears
at the end of the transmission.
6. To stop the Dual Watch feature and return to normal operation, press and
hold the [SCAN(DW)] key for two seconds again.
6.12 EMERGENCY (CHANNEL 16 USE)
Channel 16 is known as the Hail and Distress Channel. An emergency may be
defined as a threat to life or property. In such instances, be sure the trans-
ceiver is 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 mag-
netic 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, fire, heart
attack, life-threatening injury, etc.).
5. State the kind of assistance your 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 re-
sponse, try another channel.
HX280SPage 26
6.13 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 inter-
vals. In areas of heavy radio traffic, congestion on channel 16 resulting from its
use as a hailing channel can be reduced significantly in U.S. waters by using
Channel 9 as the initial contact (hailing) channel for non-emergency communi-
cations. 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
traffic, and then go back to either channel 16 or 9 for your initial contact.
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 trans-
mission by stating your Call Sign and the word “out”. Note that it is not neces-
sary 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.
Page 27HX280S
6.14 OPERATING ON CHANNEL 13
Channel 13 is used at docks, bridges and for maneuvering in port. Messages
on this channel must concern navigation only, such as meeting and passing in
restricted waters. In emergencies and when approaching blind river bends,
High power is allowed. Pressing the [H/L()] key will change the power out-
put from Low Power (1 Watt) to High (5 Watts). When you change from this
channel then return to it, low power will be automatically selected.
6.15 OPERATING ON CHANNEL 67
When channel 67 is used for navigational bridge-to-bridge traffic between ships,
Normal, High or Medium power may be used temporarily (in the USA band) by
pressing the [H/L()] key. When you select this channel again, the trans-
ceiver will revert to low power.

9. VHF MARINE CHANNEL ASSIGNMENTS
Tables on the following pages 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 Canadian
channel assignments whose counterparts in the International assignments
are duplex channels. International channels do not use “alpha” numbers.
If you call the Coast Guard on Channel 16, they will sometimes ask you to
“go to channel 22 Alpha.” This is a channel assigned to U.S.A, and Cana-
dian Coast Guards for handling distress and other calls. If your radio is set
for International operation you will go to Channel 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) control or combination of controls. Chan-
nel 22 (without an “A”) is an International duplex channel for port opera-
tions. Some radios indicate an “A” adjacent to the alpha channels on the
display; on others “alpha” is not indicated but the proper channel is se-
lected based on the U/I/C setting.
3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge
operators on inter-coastal waterways and rivers. It is also used by marine
vessels in the vicinity of these bridges for navigation and for communicat-
ing with the bridge operators. Note that a limit of 1 Watt is specified for
these channels.
4. The S/D column on the chart indicates either S (simplex) or D (duplex). Sim-
plex 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 transmission. Duplex op-
eration involves the use of one frequency for transmitting and a separate fre-
quency for receiving. On channels specified as duplex on the charts, correct
mode of operation is established automatically 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 geo-
graphic regions.
6. Marine vessels equipped with VHF radios are required to monitor Channel 16.
