Charging the Wireless 
Earpiece
Note:
●To charge the wireless earpiece, 
simply connect it to the adapter on 
the radio. It is recommended to use 
the  high-capacity battery specified 
by  the  Company  to ensure  the 
optimal operation duration  of  the 
radio. 
●Charging the  wireless  earpiece  will 
not affect the radio operation. 
●If  the  earpiece is  idle for  a long 
time, charge it at least once within 
three months. 
●If  the LED indicator  does  not  glow 
red while the wireless earpiece is 
being charged, charge the earpiece 
for  10  to  20  minutes  for  it  to  
recover to normal status. 
Charge the wireless earpiece before use. 
The  LED indicator  of  the  wireless  earpiece 
glows red  during charging and  glows blue 
when the  wireless earpiece is  fully charged. 
Also, the LED indicator  indicates the pairing 
and  connection  status.  Please  refer  to  LED 
Indication for details. 
1.  Connect the wireless audio adapter to 
the radio and secure the screw to fasten 
it. 

3.  Turn on the radio. 
Caution: The wireless earpiece can 
be  charged  only when the  radio is 
powered on. Please ensure the radio is 
powered on when charging the radio 
(with battery attached) and the wireless 
earpiece at the same time. 
2.  Fix the wireless earpiece into the 
wireless audio adapter. 
  Make sure the wireless earpiece is fully 
xed into the adapter. 

Pairing with and Connecting 
to the Adapter
Before initial connection, the wireless 
earpiece needs to be paired with the adapter 
rst. Afterwards,  the  wireless  earpiece can 
connect to the adapter without pairing. 
1.  Disconnect the wireless earpiece from 
other devices. 
2.  Connect the wireless earpiece with 
the radio. (See Charging the Wireless 
Earpiece for details)
3.  Turn on the radio, and the wireless 
earpiece will be powered up. 
4.  The wireless earpiece will be paired 
with and connected to the adapter 
automatically. 
 ●Pairing mode: The LED indicator of the 
wireless earpiece/adapter flashes red 
and blue alternatively. 
 ●Connection status: The LED indicator 
ashes blue rapidly  after the connection 
is completed. 
Wearing the Wireless 
Earpiece
Tips: There  are  three  rubber  ear 
cushions with  different  sizes provided 
with  the  wireless earpiece for your 
comfortable wearing. 
Wear the wireless earpiece after the 
connection is completed. Adjust the rubber 
ear cushion to position it into your ear 
canal, and adjust the earhook to secure the 
earpiece.   

Transmitting 
After detaching  the  wireless earpiece  from 
the adapter, you can hold down the PTT key 
on the  wireless  earpiece or  the PTT  key on 
the adapter to make a call. 
Powering On/Off
The wireless earpiece will give ring indication 
(you can hear it only when you are wearing 
the wireless earpiece) upon power-on/off. 
Powering On
 ●Automatic power-on: When attached 
to the radio via the adapter, the 
wireless earpiece will be powered on 
automatically when the radio is turned 
on. 
 ●Manual power-on: When the wireless 
earpiece is not attached with the 
adapter, you can power on the wireless 
earpiece by long pressing the PTT key 
on it. The adapter can be powered on by 
turning on the radio only. 
The LED  indicator ashes after  the wireless 
earpiece is powered on. Please refer to LED 
Indication for indication details. 
Powering Off
To power off the adapter, turn off the radio. 
To power off the wireless earpiece, long 
press the PTT key after the BT connection is 
disconnected (the LED indicator ashes blue 
slowly). The LED indicator goes out when 
the wireless earpiece is powered off. 
LED Indication
Caution: 
●When the wireless earpiece is being 
charged  on  the adapter,  the LED 
indicator glows red when charging

FCC Statement 
Changes or modifications not expressly approved by the party responsible for compliance could 
void the user’s authority to operate the equipment. 
This device complies with part 15 of FCC Rules. Operation is subject to the following two 
conditions: 
(1)     This device may not cause harmful interference, and 
(2)     This device must accept any interference received, including interference that may 
cause undesired operation 
Note: This equipment has been tested and found to comply with the limits for a Class B digital 
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable 
protection against harmful interference in a residential installation. This equipment generates, 
uses and can radiate radio frequency energy and, if not installed and used in accordance with 
the instructions, may cause harmful interference to radio communications. However, there is 
no guarantee that interference will not occur in a particular installation. If this equipment does 
cause harmful interference to radio or television reception, which can be determined by turning 
the equipment off and on, the user is encouraged to try to correct the interference by one or 
more of the following measures: 
—Reorient or relocate the receiving antenna. 
—Increase the separation between the equipment and receiver. 
—Connect the equipment into an outlet on a circuit different from that to which the receiver is 
connected. 
—Consult the dealer or an experienced radio/TV technician for help. 
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled 
environment. 
This transmitter must not be co-located or operating in conjunction with any other antenna or 
transmitter. 
IC statement 
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. 
The device has been tested and compliance with SAR limits, users can obtain Canadian 
information on RF exposure and compliance 
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils 
radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : 
(1) l'appareil nedoit 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. 
Après examen de ce matériel aux conformité aux limites DAS et/ou aux limites d’intensité 
de champ RF, les utilisateurs peuvent sur l’exposition aux radiofréquences et la 
conformité and compliance d’acquérir les informations correspondantes 
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 communication 
satisfaisante.
