Charging and Maintenance of Build-in Battery
10
X5105 has a built-in 3800mAh polymer lithium battery pack. When there is no external power supply connected, the battery pack
will supply power for the whole device. When external power supply is provided, the built-in circuit will be automatically switched to the
external power supply.
5. The maximum charging time is 10-12h. Charging will be
automatically stopped when battery is fully charged, and the
screen will display charging finishing information as shown in
right figure.
Voltage of battery is generally between 12.1~12.5V after
charging.
Charging method:
1. Enter system menu #9:Charger;
2. Rotate large knob and select 'ON', and then enable charging
function;
3. Select 'OFF' to disable charging function when operating.
4. Set voltage of external power supply between 13.5V~15.0V
and connect to the power supply port of external power source,
and then the main machine will be automatically charged.
Note: X5105 will be automatically charged and T/R indicator
light will be red when charging function is enabled and
connected with appropriate external power supply under
shutdown state. T/R indicator light will be green when
charging is finished.

Charging and Maintenance of Build-in Battery
11
○When battery is supplying power and almost running out, the power indicator at top right corner of screen will display ,
indicating that charging shall be carried out immediately or switching to external power supply is required. It will be normal if
the shell is slightly exothermic when charging.
○ Service life of the built-in battery is limited under normal use. Please contact with dealer to replace battery if capacity of battery
is obviously reduced or battery can not be charged (warranty period of battery is 3 months, replacement beyond the warranty
period shall be paid).
Rated voltage range of equipment shall not be exceeded when applying external power supply,
otherwise irreversible damages will be caused to equipment.
Once abnormal heating is found at the position close to battery on the back of shell, the
equipment shall be immediately turned off and equipment shall be placed at a safe and
ventilated place. Please contact us for proper disposal after confirming safety conditions.

Connection of External Power Supplies
12
13.8V external DC power supply is available for X5105. Current load capacity of DC power supply shall be 3A at least. Attached power lines
can be used to connect to radio and DC power supply.
DC power supply shall be connected in strict accordance with following figure to avoid reverse polarity connection.
White line shall be connected with the positive pole of power supply and metal-shielded line shall be connected
with negative pole of power supply.

Connection of External Power Supplies
13
EMC magnet ring can be applied on power lines to prevent external disturbance from entering radio via power lines and radio-
frequency interference in radio from radiating externally via power lines when external power supply is adopted for X5105. Magnet ring
shall be installed at the side closing to battery socket.
 Polarity of power lines shall be carefully inspected to avoid reverse polarity connection when external power
supply is adopted.
Limited warranty of the radio does not include damages caused by wrong connection of external power supply
or abnormal voltage.
Power line shall be twined for
2 rounds on magnet ring.
