Safety and General Information
SAFETYTRAINING INFORMATION
Your HYT 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.
This radio has been tested and complies with the FCC RF exposure limits for
“Occupational Use Only”. In addition, your HYT radio complies with the following
Standards and Guidelines with regard to RF energy and electromagnetic energy levels
and evaluation of such levels for exposure to humans:
FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC
Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.
American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels
with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz
to 300 GHz.
American National Standards Institute (C95.3-1992), IEEE Recommended Practice
for the Measurement of Potentially Hazardous Electromagnetic Fields– RF and
Microwave.
The following accessories are authorized for use with this product. Use of accessories
other than those (listed in the instruction) specified may result in RF exposure levels
exceeding the FCC requirements for wireless RF exposure.
To ensure that your expose to RF electromagnetic energy is
within the FCC allowable limits for occupational use, always
adhere to the following guidelines:
DO NOT operate the radio without a proper antenna attached, as this may damaged
the radio and may also cause you to exceed FCC RF exposure limits. A proper
antenna is the antenna supplied with this radio by the manufacturer or antenna
specifically authorized by the manufacturer for use with this radio.
DO NOT transmits for more than 50% of total radio use time (“50%duty cycle”).
Transmitting more than 50% of the time can cause FCC RF exposure compliance
requirements to be exceeded. The radio is transmitting when the “TX indicator” lights
red. You can cause the radio to transmit by pressing the “PTT” switch.
4
ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when
transmitting and only use the HYT belt-clip which is listed in instructions when
attaching the radio to your belt, etc., to ensure FCC RF exposure compliance
requirements are not exceeded. To provide the recipients of your transmission the
best sound quality, hold the antenna at least 5 cm (2 inches) from your mouth, and
slightly off to one side.
The information listed above provides the user with the information needed to make
him or her aware of RF exposure, and what to do to as-sure that this radio operates with
the FCC RF exposure limits of this radio.
Electromagnetic Interference/Compatibility
During transmissions, your HYT 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.
IMPORTANT
READ ALL INSTRUCTIONS
carefully and completely before using the
transceiver
SAVE THIS INSTRUCTION MANUAL- This instruction manual contains
important operating instructions for the Two-Way Radio
EXPLICIT DEFINITIONS
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.
5
OPERATING NOTES
When transmitting with a portable radio, hold the radio in a vertical position with its
microphone 5 to 10 cm (2 to 4 inches) away from your mouth. Keep the antenna at
least 2.5 cm (1 inch) from your head and body.
If 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.
PRECAUTIONS
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 a headset or other audio accessories
at high volume levels.
CAUTION! NEVER short the terminals of the battery pack.
NEVER connect the transceiver to a power sourc e other than the Battery listed below
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 –30°C (–22°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.
BE CAREFUL! The series transceivers employ waterproof construction, which
corresponds to IPX7 of the international standard IEC 60529 (2001), 1 m depth for 30
minutes. However, once the transceiver has been dropped, waterproofing cannot be
guaranteed due to the fact that the transceiver may be cracked, or the waterproof seal
damaged, etc.
The use of non-HYT battery packs/chargers may impair transceiver performance and
invalidate the warranty.
FCC CAUTION:
Changes or modifications to this device, not expressly approved by HYT, could void
your authority to operate this transceiver under FCC regulations.

Battery Information
Initial Use
New batteries are shipped uncharged from the factory. Charge a new battery for 5 hours
before initial use. The maximum battery capacity and performance is achieved after three
full charge/discharge cycles. If you notice the battery power runs low, please recharge the
battery.
Applicable Battery Packs
To reduce the risk of injur y, charge only the battery specified by the manufacturer. Other
batteries may burst, causing bodily injury and damage.
Caution:
1. To avoid risk of personal injury, do not dispose of batteries in a fire!
2. Dispose of batteries according to local regulations (e.g. recycling). Do not dispose as
household waste.
3. Never attempt to disassemble the battery.
Battery Tips
1. When charging your battery, keep it at a temperature among 5℃ - 40℃. Temperature
8
out of the limit may cause battery leakage or damage.
2. When charging a battery attached to a radio, turn the radio off to ensure a full charge.
3. Do not cut off the power supply or remove the battery when charging a battery.
4. Never charge a battery that is wet. Please dry it with soft cloth prior to charge.
5. The battery will eventually wear out. When the operating time (talk-time and standby
time) is noticeably shorter than normal, it is time to buy a new battery.
To Prolong Battery Life
1. Battery performance will be greatly decreased at a temperature below 0℃. A spare
battery is necessary in cold weather. The cold battery unable to work in this situation
may work under room temperature, so keep it for later use.
2. The dust on the battery contact may cause the battery cannot work or charge. Please
use clean dry cloth to wipe it before attaching the battery to the radio.
Battery Storage
1. Fully charge a battery before you store it for a long time, to avoid battery damage due
to over-discharge.
2. Recharge a battery after several months’ storage (Li-Ion & Li-polymer batteries: 6
months), to avoid reducing battery capacity due to over-discharge.
3. Store your battery in a cool, dry place under room temperature, to reduce
self-discharge.
Charging the Battery
When the charge indicator flashes red and an alert tone sounds at intervals of ten
seconds indicating the battery power runs low, please recharge the battery. Use only the
charger specified by the manufacturer. The charger’s LED indicates the charging
progress.
Please follow these steps to charge your radio using the switching power:
9
1. Plug the AC connector of the switching power into the AC outlet socket.
2. Plug the Mini USB connector of the switching power into the Mini USB jack of the
radio.
3. Make sure the radio is in well contact with the switching power. The charging process
initiates when the charge indicator glows red.
4. The charge indicator glows green when the battery is fully charged. Please remove
the radio then.
