RF EXPOSURE SAFETY STATEMENT
SAFETY INFORMATION
Your wireless handheld portable transceiver contains a low power transmitter. 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 guidelines, this transmitter and its antenna must maintain a separation distance 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.
If you use a headset accessory for this radio, with the radio worn on
your body, use only the Vertex Standard belt clip for this transceiver, and
ensure that the antenna is at least 1 inch (2.5 centimeters) from your
body when transmitting.
Use only the supplied antenna. Unauthorized antennas, modifications,
or attachments could damage the transmitter, and may violate FCC regulations.

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 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 fixed mount 25 W radio transmission
expected distances can be greater than 15 miles, for a portable 6 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 waterway, 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 42 section 10.
3.2 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 transceiver 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 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, 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.
)
Page 9HX751
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.
3.3 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 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 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
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, immediately 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.
HX751Page 10
3.4 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

4. GETTING STARTED
4.1 RADIO CARE
CAUTION
Before following the instructions below, insure the speaker microphone
jack, antenna and battery are 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 condition.
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-39 Charger Cradle with the NC-88B 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-88B, E-DC-19A, and E-DC-6
will charge a completely discharged FNB-V99LI battery pack in about 8 hours.
The FNB-V99LI is a high performance Li-Ion battery providing high capacity in
a compact package.
CAUTION
To avoid risk of explosion and injury, FNB-V99LI 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, especially when removed from the transceiver. Please observe the following precautions:
DO NOT SHORT BATTERY PACK TERMINALS: Shorting the terminals that
power the transceiver can cause sparks, severe overheating, burns, and battery 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 surfaces 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 transceiver are not exposed. The terminals that are exposed on the battery pack
HX751Page 12
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:
Battery packs should be charged only in non-hazardous environments;
Use only STANDARD HORIZON-approved batteries;
Use only a STANDARD HORIZON, (a Marine Division of VERTEX
STANDARD) approved charger. The use of any other charger may
cause permanent damage to the battery.
Follow charging instructions provided with the chargers.
Keep 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 batteries.
