User Safety Information
READ THIS IMPORTANT INFORMATION ON SAFE AND
EFFICIENT OPERATION BEFORE USING YOUR
QUANTUN PORTABLE TWO-WAY RADIO.
Compliance with RF Energy Exposure Standards
Your Quantun 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 Quantun two-way radio complies with the following of RF energy exposure
standards and guidelines:
United States Federal Communications Commission, Code of Federal Regulations;

Getting Started
Battery
Safety Precautions
The battery is not fully charged at the factory. It is recommended to charge the new
battery for 5 hours before using it. Also, batteries that may have set longer than 2 months
since the last charge should be charged before using it. The battery capacity will be
optimum after being charged/discharged two or three times. When the battery’s charge is
depleted, charge the battery or replace the battery with a new one.
Caution:
1. Do not short circuit the battery terminals or discard the battery in fire. Never attempt
to disassemble the battery.
2. Never charge a battery that is wet. Please dry it with soft cloth prior to charge.
3. Do not return fully charged batteries to the charger for an “extra boost”. This action
will significantly reduce battery life.
4. Dispose of batteries according to local regulations (e.g. recycling). Do not dispose as
household waste.
Battery Tips
1. The battery should be charged at 5 ~ 40 , temperature ou℃℃ t of this range could
result the battery not fully charged.
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. The battery will eventually wear out. When the operating time (talk-time and standby
time) is noticeably shorter than normal performance, it is time to buy a new battery.
To Prolong Battery Life
Battery performance will be greatly decreased at a temperature -20 below.℃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 battery life. Please use clean dry cloth to
wipe it before the attaching the battery to the radio.
Battery Storage

11
1. Considering the battery's self-discharge characteristics, fully charge the battery prior
to long time storage, to avoid battery damage due to over-discharge.
2. Recharge the battery after 6 months’ storage, to avoid reducing battery capacity due
to over-discharge.
3. Notice the ambient humidity and temperature for the battery storage. Please store it in
cool dry area under room temperature, to reduce self-discharge capacity.
Charging the Battery
When the radio top LED flashes red and three beeps sound every 10 seconds indicating
the battery power runs low, please recharge the battery.
You are recommended to use Quantun authorized charger. Charger LED will indicate the
charging status.
Please follow these steps to charge your radio using the switching power adapter
or desktop charger:

1. Plug theAC connector of the switching power adapter into the AC outlet socket.
2. Plug the DC connector of the switching power adapter into the DC jack of the charger.
3. Place the radio with the battery attached or the battery alone in the charger.
4. The charging process initiates when LED glows red, and is completed when LED
glows green.
Note: Make sure the radio is attached with a battery before charging, and is
powered off during charging.

Antenna
Stubby antennas are ideal for communication within limited range. Fine and long antennas
optimizes communication coverage, ideal when the radio is worn on the belt because they
are flexible and soft.
Rainy days or forest locations may narrow your communication range, please repare in
advance to avoid potential inconvenience.
