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 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 47 section 16.
3.2 ABOUT FRS (FAMILY RADIO SERVICE
)
FRS is a private, two-way, very short-distance voice
communications service for facilitating family and
group activities
Areas of Operation
You may operate your FRS radio in the United States and certain locations
specified by the FCC [95.192].
If you want to use FRS aboard a vessel or aircraft owned or operated by a U.S.
citizen or company, you will need permission from the captain of the vessel.
You must share the channel with other users [95.191(b)]. There is no meaningful way to share the channel with others unless you listen before transmitting and wait until the channel is available before you transmit. To listen

HX471S Page 9
3.3 ABOUT RECEIVE ONLY CHANNELS and FREQUENCIES
AM/FM Broadcast Bands
The AM/FM bands contained within the HX471S are the same channels you
use every day to listen to music, news and commentary with your car or
home stereo.
The AM broadcast band currently extends from 530
to 1700 kHz. Channels are spaced in even 10 kHz
increments; i.e.: 530, 540, 550, ... , 1600 kHz in the
United States and Canada. Elsewhere, channels are
spaced in 9 kHz increments, i.e.: 531, 540, 549, etc.
The FM broadcast band in the United States extends
from 88 to 108 MHz. Channels are assigned at 200
kHz increments; i.e.: 88.1, 88.3, 88.5, ... , 107.9. The
channels from 88.1 to 91.9 are reserved for noncommercial educational stations. Outside the United States and Canada,
the boundaries and channel spacing vary. In Japan, the band starts at 76
MHz. In Western Europe, the band generally runs from 88-108 MHz, but
channels can be irregularly spaced, i.e.: 101.25 MHz.
AIR (Aircraft) Bands
The AM VHF aeronautical communications band lies
between 108.000 MHz and 136.975 MHz. This frequency spectrum can be divided into a lower and
upper range. The lower range between 108.000 MHz
and 118.000 MHz is primarily used for navigational aids such as the ILS Instrument Landing Systems, DME - Distance Measuring Equipment, and
VOR’s - Very High Frequency Omni Range. The lower range offers very little
in the way of voice communications, it does however provide someone with
a working knowledge of Morse code the opportunity to identify various beacons. The upper range of the aeronautical band 118.000 MHz to 136.975
MHz is where the majority of voice communications can be monitored. Communications in the VHF band are transmitted in AM mode and most if not all
compatible receivers automatically default to this mode. Frequencies within
the aeronautical range are spaced in increments of 25 kHz, as such you will
find transmissions at 118.000, 118.025, 118.050 MHz etc.
The frequency(s) you monitor will determine the nature of traffic you will
hear. As previously mentioned frequencies in the lower range of the aero-
HX471SPage 10
nautical band are mostly occupied by navigational equipment and transmit
non voice signals in Morse code. If you select a frequency in the upper
range the air is suddenly filled with conversations between pilots and air
traffic controllers, pilots and their company dispatchers, flight service stations, and ATIS broadcasts. Frequencies within the aeronautical band are
designated according to their usage.
Refer to the page 23 for operation.

4. GETTING STARTED
If the radio has never been used, or its charge is depleted, it may be charged
by connecting the CD-25 Charger Cradle with the NC-72 battery charger, as
shown in the illustration. If 12V DC power is available, the optional E-DC-19
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-72, E-DC-19 and E-DC-6 will
charge a completely discharged FNB-80LI battery pack in about 3 hours.
4.1 BATTERIES AND CHARGERS
The FNB-80LI is a high performance Lithium-Ion battery providing high capacity in a very compact package.
CAUTION
To avoid risk of explosion and injury, FNB-80LI battery pack should only
be removed, charged or recharged in non-hazardous environments.
4.1.1 BATTERY SAFETY
Battery packs for your transceiver contain Lithium-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.
HX471SPage 12
Battery Maintenance
For safe and proper battery use, please observe the following:
r Battery packs should be charged only in non-hazardous environments;
r Use only STANDARD HORIZON-approved batteries;
r 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.
r Follow charging instructions provided with the chargers.
r Keep the battery contacts clean.
Battery Storage
Store 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!
LITHIUM-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 lithium-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 lithium-ion batteries.
HX471S Page 13
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-25 Charger Cradle with the NC-72 battery charger, as
shown in the illustration. If 12V DC power is available, the optional E-DC-19
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-72, E-DC-19 and E-DC-6 will
charge a completely discharged FNB-80LI battery pack in about 3 hours.
