WARNING
This radio is capable of transmitting on VHF Marine.
The FCC allows the use of VHF Marine band on water areas only. However the FCC does not allow
the use of the VHF Marine band when on land. If persons use the VHF Marine Band on land and
interfere with others communicating, the FCC will be notified and search for the interference.
Responsible parties found to be transmitting on the VHF Marine Band on land could be fined up to
$10,000 for the first offense.
The FCC does however prohibit the use in aircraft.
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.
NOTE
This radio telephone complies with the requirements of RTCM Paper 56-95/SC101 Standards for
digital selective calling (DSC) for Marine transceivers.

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 25W radio transmission expected distances can be greater than 15 miles, for a portable
5W 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 ?? section 11.

Operating Manual
4. GETTING STARTED
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-88 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-88, E-DC-19A and
E-DC-6 will charge a completely discharged FNB-V99LI battery pack in about 8 hours.
4.1 BATTERIES AND CHARGERS
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.
4.1.1 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 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 nickel-cadmium 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.
4.1.2 BATTERY CHARGING
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-88 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-88, E-DC-19A and
E-DC-6 will charge a completely discharged FNB-V99LI battery pack in about 8 hours.
4.1.3 BATTERY INSTALLATION/REMOVAL
1. Turn the transceiver off.
2. To install the battery pack, insert the battery pack into the battery nest on the bottom of the
transceiver, then turn the Battery Pack Lock to the “LOCK” position by a coin.
3. To remove the battery pack, open the Battery Pack Lock on the bottom of the transceiver, then
slide out the battery from the transceiver.
4.1.4 USING THE CD-39 CHARGER CRADLE
1. Turn the transceiver off.
2. Insert the DC plug from the NC-88 into the DC jack on the CD-39 rear panel, then plug the
NC-88 into the AC line outlet.
3. Insert the HX750S (with the battery pack) into the CD-39; the antenna should be at the left side
when viewing the charger from the front.
