Charging and Maintenance of Build-in Battery

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.

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.

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 and Maintenance of Build-in Battery

○

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

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

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.

Power line shall be twined for

2 rounds on magnet ring.

Close to interface to

greatest extent

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.

Operation

X5105 adopts multi-function menu mode to enable or disable various functions. All functions are distributed in 9 menu pages, and each page of menu has four functions that can be selected.

Menu can be switched in following methods:
