INTRINSIC SAFETY
Versions of the JHS-431 which display the “EX” marking on the serial
number seal.
The approval rating for these models are II2G Ex ib IIA T3 Gb and II 2D Ex
tb IIIC T160°C Db IP67.
WARNING! NEVER charge the BP-227AXD (with/without the transceiver) in an
explosive atmosphere. The optional battery chargers are not approved as Intrinsically
Safe.
When the transceiver is used in a hazardous area, the BP-227AXD MUST be
attached, either the jack cover or HM-138 MUST be attached to the speaker-
microphone connector.
KEEP the transceiver and the BP-227AXD clean to avoid any risk of ignition due to
the build-up of electrostatic charges.
Repair of JRC radios should only be carried out by authorized JRC distributors. In
particular, repair of ATEX approved radios can
ONLY be done by JRC to maintain the intrinsically safe rating. NEVER attempt to
repair an ATEX approved radio. Only JRC has
the repair expertise and procedures to maintain the ATEX approval.
Contact your JRC distributor or authorised dealer for details.
The equipment can be used without the microphone but with the jack cover.

SAFETY TRAINING INFORMATION
CAUTION
WARNING
Your 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
intended for use by the "General Population" in an uncontrolled environment.
Electromagnetic Interference/Compatibility
During transmissions, your radio generates RF energy that can possibly
cause interference with other devices or systems. To avoid such interference,
turn off the radio in areas where signs are posted to do so.
DO NOT operate the transmitter in areas that are sensitive to electromagnetic
radiation such as hospitals, aircraft, and blasting sites.
Occupational/Controlled Use
The radio transmitter is used in situations in which persons are exposed as consequence of their
employment provided those persons are fully aware of the potential for exposure and can exercise control
over their exposure.

Foreword
READ ALL INSTRUCTIONS carefully and completely before using the transceiver.
SAVE THIS INSTRUCTION MANUAL-This instruction manual contains important operating
instructions for the JHS-431 UHF TRANSCEIVER.
Explicit Definition
Word Definition
WARNING:Personal injury, fire hazard or electric shock may occur.
CAUTION:Equipment damage may occur.
NOTE:If disregarded, inconvenience only. No risk of personal injury, fire or electric shock.
Operating Notes
zWhen transmitting with a portable radio, hold the radio in a vertical position with its
microphone 5 to 10 centimeters (2 to 4 inches) away from your mouth. Keep the antenna at
least 2.5 centimeters (1 inch) from your head and body.
zIf you wear a portable two-way radio on your body, ensure that the antenna is at least 2.5
centimeters (1 inch) from your body when transmitting.
Precaution
WARNING! NEVER hold the transceiver so that the antenna is very close to, or touching exposed
parts of the body, especially the face or eyes, while transmitting. The transceiver will perform best if
the microphone is 5 to 10 cm (2 to 4 inches) away from the lips and the transceiver is vertical.
WARNING! NEVER operate the transceiver with audio accessories at high volume levels.
CAUTION! NEVER short the terminals of the battery pack.
NEVER connect the transceiver to a power source other than the BP-227AXD. Such a connection will
ruin the transceiver.
DO NOT push the PTT when not actually desiring to transmit.
AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below -20°C (-
4°F) or above +60°C (+140°F).
DO NOT modify the transceiver for any reason.
MAKE SURE the flexible antenna and battery pack are securely attached to the transceiver, and that
the antenna and battery pack are dry before attachment. Exposing the inside of the transceiver to
water will result in serious damage to the transceiver. The use of non-BP-227AXD battery
packs/chargers may impair transceiver performance and invalidate the warranty.

Handling precaution
DANGER
The NZB-139/NZB-141/NZB-142 battery chargers are not intrinsically safe type. Do not
keep or use the NZB-139/NZB-141/NZB-142 in the presence of any explosive or
combustible gas (*1). It may cause an explosion or fire.
Only a few kinds of explosive gases and vapors are defined to be non-harmful to the
JHS-431. Do not use the JHS-431 in the presence of any other explosive or
combustible gas. It may cause an explosion or fire.
Always use the dedicated battery pack (BP-227AXD) of the JHS-431. When other
battery pack is used, it may cause an explosion or fire.
Never disassemble, remodel, or repair the JHS-431 and its components. It may cause
a fire or failure. Particularly, disassembling in the presence of any explosive or
combustible gas may cause an explosion or fire.
Do not replace the battery pack in the presence of any explosive or combustible gas.
Replacing in such a hazardous area may cause an explosion or fire.
If the JHS-431 is dropped to the ground or damaged, send it to your local JRC distributor or
sales office for check and repairing. Do not use it in the presence of any explosive or
combustible gas. Using the broken product in a hazardous area may cause an explosion or
fire.
viii
WARNING
Do not put the battery pack in a microwave oven or in a high-pressure container.
The battery pack may leak its content, become hot, or explode.
If the content of the battery pack jumps into your eyes, do not rub. This risks
corneal damage. Try washing with running water. Then, consult your doctor.
Do not disassemble or remodel the battery pack. This may cause the battery
pack to explode, to overheat, ignite or to leak the harmful content (organic
solvent).
Do not solder wires directly to the charging and output terminals of the battery
pack. This may cause the battery pack to explode, to overheat, ignite or to
leak the harmful content (organic solvent).
Do not short-connect the charging terminals of the charger. The short-connected
terminals will cause a fire or failure.
When finding the charger troubled, pull out the plug from the outlet, then call
your local JRC distributor or sales office. Never use the disabled charger. It
may cause a fire or give you electric shocks.
Do not throw the battery pack into fire. Fire and heat may cause the battery
pack to explode, to overheat, ignite or to leak the harmful content (organic
solvent).
