User Safety, Training, and General Information
READ THIS IMPORTANT INFORMATION ON SAFE AND EFFICIENT OPERATION
BEFORE USING YOUR HYT PORTABLE TWO-WAY RADIO.
Compliance with RF Energy Exposure Standards
Your HYT two-way radio is designed and tested to comply with a number of national and
international standards and guidelines (listed below) regarding human exposure to radio
frequency electromagnetic energy. This radio complies with the IEEE (FCC) and ICNIRP
exposure limits for occupational/controlled RF exposure environment at duty cycles of up
to 50% talk-50% listen and should be used for occupational use only. In terms of
measuring RF energy for compliance with the FCC exposure guidelines, your radio
radiates measurable RF energy only while it is transmitting (during talking), not when it is
receiving (listening) or in standby mode.
Note: The approved batteries supplied with this radio are rated for a 5-5-90 duty cycle
(5% talk-5% listen-90% standby), even though this radio complies with the FCC
occupational RF exposure limits at duty cycles of up to 50% talk.
Your HYT two-way radio complies with the following of RF energy
exposure standards and guidelines:
zUnited States Federal Communications Commission, Code of Federal Regulations;
47CFR part 2 sub-part J
zAmerican National Standards Institute (ANSI)/Institute of Electrical and Electronic
Engineers (IEEE) C95. 1-1992
zInstitute of Electrical and Electronic Engineers (IEEE) C95. 1-1999 Edition
zInternational Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
Operational Instructions and Training Guidelines
To ensure optimal performance and compliance with the occupational/controlled
environment RF energy exposure limits in the above standards and guidelines, users
should transmit no more than 50% of the time and always adhere to the following
procedures:
Transmit and Receive
To transmit (talk), push the Push-To-Talk (PTT) button; to receive, release the PTT button.
Hand-held radio operation
Hold the radio in a vertical position with the microphone one to two inches (2.5 to 5 cm)
away from the lips.
Body-worn operation
zAlways place the radio in an HYT approved clip, holder, holster, case, or body
harness for this product. Use of non-HYT-approved accessories may exceed FCC
RF exposure guidelines.

Antennas & Batteries
zUse only HYT approved, supplied antenna or HYT approved replacement antenna.
Unauthorized antennas, modifications, or attachments could damage the radio and
may violate FCC regulations.
zUse only HYT approved, supplied batteries or HYT approved replacement batteries.
Use of non- HYT -approved batteries may exceed FCC RF exposure guidelines.

User Safety Information
READ THIS IMPORTANT INFORMATION ON SAFE AND EFFICIENT OPERATION
BEFORE USING YOUR HYT PORTABLE TWO-WAY RADIO.
◇ Only qualified technicians are allowed to maintain this product.
◇ To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio
in any place where posted notices instruct you to do so. Hospitals or health care
facilities may be using equipment that is sensitive to external RF energy. When on
aircraft, turn off your radio when airline crew instruct you to do so.
◇ When in vehicles with an airbag, do not place a portable radio in the area over an
airbag or in the airbag deployment area.
◇ Turn off your radio prior to entering any area with a potentially explosive atmosphere.
Do not remove, install, or charge batteries in such areas.
◇ To avoid possible interference with blasting operations, turn off your radio when you
are near electrical blasting caps.
◇ Do not use any portable radio that has a damaged antenna. If a damaged antenna
comes into contact with your skin, a minor burn may result.
◇ Do not expose the radio in direct sunlight for a long time or place it close to a heating
source.
◇ When transmitting with a portable radio, hold the radio in a vertical position with its
microphone about 5 centimeters away from your mouth.
◇ If you wear a portable two-way radio on your body, ensure that the antenna is at least
2.5 centimeters from your body when transmitting.
◇ The communication range will be impacted in rainy or cloudy days or when you are in
forest.

Battery Information
Initial Use of the Battery
The battery is not fully charged at the factory. Please charge the new battery before initial
use. In general, the battery should be charged for 12 hours before initial use, which is
suitable for Ni-Cd, Ni-MH or Li-ion battery charged with slow or rapid charger. It is
recommended to take this step during the first three times of use. When the battery power
is low, it needs to be charged.
Applicable Battery Packs
Charge only the HYT approved battery packs. Other batteries may burst and cause
personal injury.
Safety attention
1. Conductive metals including jewelry, key, etc, may result in short circuit, discharge,
generation of a large quantity of heat, or leakage when coming into contact with battery
contacts or electrodes. To avoid damage to articles or human injury, treat any battery with
care.
2. Do not short out the battery terminals or dispose of the battery in fire. Never attempt to
disassemble the battery. If discarded, the battery should be thrown into dedicated battery
recycle box.
Normal operation
★Please charge the battery indoor to ensure the optimal charging effect.
★In general, the battery can be removed if the charger indicator turns from red to green.
★Turn off the radio when charging the battery inside the radio.
★Do not charge the battery if its power hasn’t been used up (if the power used up, the
battery meter flashes), otherwise, the battery life will be shortened.
★Do not return fully charged batteries to the charger for an “extra boost”. This action will
significantly reduce cycle life.
To prolong battery life
★Battery performance will be greatly decreased under -20℃temperature. Please use
back-up battery in cold weather. The cold battery unable to work in this situation may work
under room temperature, so keep it for later use.
★The dust on the battery contact may affect the life cycle of the battery. Please use
clean dry cloth to wipe it before the insertion of the battery into the radio.
Battery storage notice
1. Due to the self-discharge, the battery which will not be used for a long time should be
stored after full charge to avoid the damage to the battery because of over-discharge.

TC－1600 Owner’s Manual
7
2. Take out the battery stored for about 6 months to charge it, to avoid the influence of
electrolyte over-discharge on battery capacity.
3. Notice the ambient humidity and temperature for the battery storage. Please store it in
cool dry area with room temperature, to decrease self-discharge.
Battery charging
You are recommended to use HYT-approved, supplied charger; Charger LED will indicate
the charging status.
1. Plug the power cable into the adapter.
2. Plug the DC socket of adapter into the DC jack on the rear of the charger.
3. Insert the battery or the radio with battery into the charger cup.
4. Plug the AC socket of adapter into an AC outlet.
5. Make sure that the battery connectors are in contact with the charging terminals; the
charger LED glows red and charging begins.
6. The charger LED glows green when the battery is fully charged in about 2 hours,
please remove the battery or the radio with battery from the charger.
NOTE:
1. When a fully charged battery is inserted into the charger:
¾LED glows red, indicating charge is in absorption stage, which helps to charge
the battery to its full capacity. In this stage, the charging current is very small
and the stage will last about less than 5 minutes and then LED turns green.
¾LED glows green.
¾LED goes from red to orange and finally to green. And the LED glows orange
for about 10 seconds.
Any status is possible and normal and will not affect normal operation.
