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 exceed 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.
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.

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 injury, 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℃to ensure a full charge. Temperature out of the
limit will significantly reduce battery life.
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.

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 3 months’ storage, to avoid reducing battery capacity due to over-discharge.
3. When storing your battery, keep it in a cool, dry place under room temperature.

charger
Please follow these steps:
1. Plug the power cord into the adapter.
2. Plug the AC connector of the adapter into the AC outlet socket.
3. Plug the DC connector of the adapter into the DC socket on the back of the charger.
4. Place the radio with the battery attached, or the battery alone, in the charger.
5. Make sure the battery is in well contact with the charging terminals. The charging process initiates when the red LED
lights.
6. The greed LED lights about 3 hours later indicating the battery is fully charged. Then remove the radio with the battery
attached or the battery alone from the charger.
Troubleshooting (MCU intelligent rapid-rate charger only):

11
When troubleshooting, always observe the color of the LED:
No LED Indication?
1. Make sure that the power cord is plugged into an appropriate AC outlet.
Red LED flashes rapidly (0.2s on/0.2s off)?
1. Remove the battery from the charger, and:
a) Make sure that it is a HYT authorized battery. Other batteries may not charge.
b) Remove power from the battery charger, and clean the gold metal, charging contacts of the battery and charger,
using a clean dry cloth.
2. The battery temperature may be above 45℃.
3. Defective battery. Please replace it with a new one.
4. Power up the charger and place the battery back into the charger pocket. If the LED indicator continues to flash red,
replace the battery.
Note:
When the battery charger detects the proper battery conditions, rapid charging begins automatically (steady red LED).
If the battery temperature is above 45℃, the charger will report the fault by flashing red LED rapidly (0.2s on/0.2s off),
and will not charge until the battery temperature is below 45℃, with red LED solidly glows (Ni-MH battery only).
Antenna Information
1. Stubby antenna is ideal for communication within limited range. Thin and long antenna optimizes communication
coverage, and its flexible and soft characteristic makes it ideal for wearing your radio on the belt.
