WARNING
This radio generates RF electromagnetic energy during transmit mode. This
radio is designed for and classified as Occupational Use Only, meaning it
must be used only during the course of employment by individuals aware of
the hazards, and the ways to minimize such hazards. This radio is not in-
tended for use by the General Population in an uncontrolled environment.
CAUTION
To ensure that your expose to RF electromagnetic energy is within the FCC
allowable limits for occupational use, always adhere to the following guidelines:
SAFETY INFORMATION
This radio is NOT approved for use by the general population in an uncon-
trolled environment. This radio is restricted to occupational use, work re-
lated operations only where the radio operator must have the knowledge to
control its RF exposure conditions.
PWhen transmitting, hold the radio in a vertical position with its microphone
1 to 2 inches (2.5 to 5 cm) away from your mouth and keep the antenna at
least 1 inch (2.5cm) away from your head and body.
PThe radio must be used with a maximum operating duty cycle not exceed-
ing 50 %, in typical Push-to-Talk (Manual PTT or VOX) configurations.
DO NOT transmit for more than 50 % of total radio use time (50 % duty
cycle). Transmitting more than 50 % of the time can cause FCC RF expo-
sure compliance requirements to be exceeded.
The radio is transmitting when the red LED on the front panel of the radio
is illuminated. You can cause the radio to transmit by pressing the PTT
button or by speaking into the microphone if using the optional VC-24
VOX accessory.

ABOUT VHF MARINE RADIO
The radio frequencies used in the VHF marine band lie between 156
and 158 MHz with some shore stations available between 161 and 163
MHz. The marine VHF band provides communications over distances
that are essentially “line of sight” (VHF signals do not travel well through
objects such as buildings, hills or trees). Actual transmission range de-
pends much more on antenna type, gain and height than on the power
output of the transmitter. The approximate distance a portable 5W radio
may communicate  is about 5 miles in if there are no obstructions (build-
ings, hills etc.) restricting line of sight transmission.
ABOUT LMR CHANNELS
The HX370S is capable of PC programming 40 LMR (Land Mobile Ra-
dio) channels by a dealer. The frequency range is 137 to 174MHz which
may be setup for 25kHz (wide) or 12.5kHz (narrow) channel stepping
with CTCSS and DCS signaling. Contact your dealer or Standard Horizon
Product Support (800-767-2450) for further details.

be charged completely in 10 hours.
WARNING
PThe FBA-25A was designed as a backup battery pack, and it can be
used to power the transceiver if you are in an area that does not require
the use of an intrinsically safe radio. The HX370SAS is only intrinsically
safe with the use of the FNB-V57IS battery pack.
PDo not reverse-connect the battery terminals.
PDo not parallel-connect the battery terminals.
PDo not change batteries in hazardous locations.
PTo reduce the risk of explosion, recharge the batteries outside of hazard-
ous locations.
PDo not connect/disconnect the E-DC-19A or E-DC-6 DC Cables in a
hazardous location.
Important Notes:
PThe NC-88 is not designed to power the transceiver for operation (re-
ception or transmission).
PDo not leave the charger connected to the transceiver for continuous
periods in excess of 24 hours. Long term overcharging can degrade the
Ni-MH battery pack and significantly shorten its useful life.
PIf using a charger other than the NC-88/CD-26, or if using a battery pack
other than the FNB-83/FNB-V57IS, follow the appropriate instructions
provided with the charger/battery. Contact your Dealer if you have any
doubts about the appropriateness of the particular charger or battery
pack you intend to use.Figure 2
