■DO NOT operate the transceiver without a proper antenna attached, as this
m
ay damage the transceive
r
and may also exceed exposure limits.
■Refer service to qualified technicians only.

CHARGING THE BATTERY PACK
The battery pack is not charged at the factory; charge it before use.
Initially charging the battery pack after purchase or extended storage will not bring
the battery pack to its normal operating capacity. After repeating the
charge/discharge cycle two or three times, the capacity will increase to best status
You should charge or change the battery pack if the battery’s power is weak.
CAUTION:
●Use the original battery pack only. It is likely to explode or hurt your body if you use other battery.
●Don’t short-circuit the terminals or put it in fire. Don’t attempt to open the unit.
●The ambient temperature should be between 0* to 40* while charging is in progress.
●Charging beyond this range may not fully charge the battery.
●Always switch OFF the transceiver equipped with a battery pack before charging. Using the
transceiver while charging, it will interfere with correct charging.
●Don’t cut off the power or take off the battery during the charging process or else it will interfere with
correct charging.
●The battery pack life is over when its operating time decreases even though it is fully and correctly
charged. Replace the battery pack.
●Don’t recharge the battery pack if it is already fully charged or it will short the life of the battery.
●Don’t charge the battery pack or transceiver while it is wet. Please wipe up it first to avoid danger.

04.CHARGING
04CHARGING
■Put the DC plug of the transformer into the DC socket of the charger unit.
■Connected the supplied transformer to the AC jack
■Slide the battery or the transceiver with a battery pack into the charger.
■Make sure the battery pack contacts are in contact with the charging terminals, and the
charger LED is on, it begins to charge.
■After charging the supplied battery pack for 4 hours, remove it or the transceiver equippe
d
with it from the charger. The charger light turns to green automatically after charging is
completed.
CAUTION:
●It is abnormal in case of the charger glisteningly before sliding the battery pack into the
charger.
●Don’t replace the battery pack until the indicator light is stable.
●Make sure contact well, LED indicates red when it is charging, if LED always blinking the
battery pack is damaged or over the environment temperature. MAINTENANCE 05
Charging Operation
If the transceiver indicator displays , it means the battery pack is out of power ,
p
lease charge it. Please always use the original charger. The charger’s indicator shows
the charging status below.
Please charge the battery pack as follow:
05.MAINTENANCE
■Don’t carry the transceiver by the antenna or microphone directly.
■Use a soft, clean, dry cloth to clean the transceiver.
■Please cover the speaker/microphone jacks with the supplied cover when the transceiver is
not in used.
■The keypad, knobs and case will become dirty after long use; you can use the soft detergen
t
and cloth to clean it.

◆The battery pack may not be installed
correctly.
Remove it and install it again.
pi Battery power dies shortly after charging
◆The battery pack life is finished. Replace
the batterypack with a new one.
Cannot talk to or hear other members in
your group
◆Make sure you are using the same
frequency and CTCSS/DCS tone as the other
members in your group.
◆Other group members may be too far away.
Make sure
you are within the range of the other radios.
Other voices (besides group members)
are present on the channel.
◆Change the CTCSS/DCS tone. Be sure to
change the CTCSS/DCS on all radios in
your group.
Caution:
1) When use VOX by earpiece, press the PTT key to exit.
2) If use PTT/VOX earpiece, It is not allowed to switch to VOX directly during PTT call.
Because it
will transmit without ending.
Please switch to PTT to return to normal.

ICWaring
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject
to the following two conditions: (1) this device may not cause interference, and (2) this device must
accept any interference, including interference that may cause undesired operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio
exemptsdelicence.L'exploitation est autorisée aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d'en compromettre le fonctionnement.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna
of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To
reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary
for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut
fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour
l'émetteur par Industrie Canada.
Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs,
il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée
équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une
communicationsatisfaisante.
RF Exposure Compliance and Control Guidelines and Operating Instructions
To control your exposure and ensure compliance with the occupational/controlled environment
exposure limits always adhere to the following procedures.
Guidelines:
Do not remove the RF Exposure Label from the device.
User awareness instructions should accompany device when transferred to other users.
Do not use this device if the operational requirements described herein are not met.

Operating Instructions:
Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the
Push-To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting 50% of
the time, orless, is important because this radio generates measurable RF energy exposure only
when transmitting (in terms of measuring for standards compliance).
Hold the radio in a vertical position in front of face with the microphone (and the other parts of
the radio, including the antenna) at least one inch (2.5 cm) away from the nose. Keeping the
radio at the proper distance is important because RF exposures decrease with distance from the
antenna. Antenna should be kept away from eyes.
When worn on the body, always place the radio in a Xiamen Puxing Electronics Science&
Technology Co., Ltd approved clip, holder, holster, case, or body harness for this product.
Using approved body-worn accessories is important because the use of Xiamen Puxing Electronics
Science&Technology Co., Ltd or other manufacturer’s non-approved accessories may result in
exposure levels, which exceed the FCC’s occupational/controlled environment RF exposure limits.
If you are not using a 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 at least 2.5 cm (one inch) from
the body when transmitting. Keeping the radio at the proper distance is important because RF
exposures decrease with increasing distance from the antenna.
Use only Xiamen Puxing Electronics Science&Technology Co., Ltd approved supplied or replacement
antennas, batteries, and accessories. Use of non-manufacturer-nameapproved antennas, batteries, and
accessories may exceed the FCC RF exposure guidelines.
