User Safety, Training, and General 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:
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
zInternational Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
zMinistry of Health (Canada) Safety Code 6. Limits of Human Exposure to Radio
Frequency Electromagnetic Fields in the Frequency Range from 3KHz to 300GHz,
1999

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 a Quantun approved clip, holder, holster, case, or body
harness for this product. Use of non-Quantun-approved accessories may exceed
FCC RF exposure guidelines.
zIf you do not use a Quantun approved body-worn accessory and are not using the
radio in the intended use position in front of the face, then ensure the antenna and the
radio are kept one inch (2.5 cm) from the body when transmitting.
Antennas & Batteries
zUse only Quantun approved, supplied antenna or Quantun approved replacement
antenna. Unauthorized antennas, modifications, or attachments could damage the
radio and may violate FCC regulations.
zUse only Quantun approved, supplied batteries or Quantun approved replacement
batteries. Use of non-Quantun-approved batteries may exceed FCC RF exposure
guidelines.

Getting Started
Battery
Safety Precautions
The battery is not charged at the factory. It is recommended to charge the new battery
before using it. Also, batteries that may have set longer than 2 months since the last
charge should be charged before using it. please charge it for 12 hours, which applies for
Ni-Cd, Ni-MH and Li-Ion battery charged with slow or rapid rate charger. 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. The battery should be charged at 5 ~ 40 , temperature out of this range could℃℃
result the battery not fully charged.
3. When charging a battery attached to a radio, turn the radio off to ensure a full charge.
4. Do not cut off the power supply or remove the battery when charging a battery.
5. If the operation time will not increase even though the battery is properly charged, this
means the battery life cycle is over, please replace with a new one.
6. Do not return fully charged batteries to the charger for an “extra boost”. This action
will significantly reduce battery life.
7. Never charge a battery that is wet. Please dry it with soft cloth prior to charge.
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

12
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 30 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.

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.
Accessory Installation
