Charging and maintenance of internal battery
X5105 has a built-in 3800mAh battery pack. When the external power supply is not
connected, the battery pack supplies power to the X5105, when the X5105 is connected
with an external power supply, the circuit inside the machine automatically switches to
the external power supply.
Charging method:
1In the menu-7, select [CHG], select “CHG ON”, start charging function.
2select “Charger ON”, Start boot-strap charging function.
3Select “Charger OFF” Shut down boot-strap charging function. If it is power off, then
the default is start boot-strap charging function.
4The external power supply voltage is set between 13.5V-15.0V and the power supply
is connected to the X5105 external power supply.
The host will automatically start charging.
5The maximum charge time is about 12~15 hours. When the battery is full, the
charging will stop automatically.
When the battery is powered for X5105, when the battery power is about to run out, the
power indication sign on the upper right corner of the screen is displayed as . At this
point, the X5105 should be charged or switched to an external power supply. During the
charging process, the casing of the machine has a slight fever.
Normally, the lifetime of the internal battery is about 3 years. When there is a significant
drop in capacity or charging failure, contact the dealer to replace the battery (outside
the warranty period, you will be charged for a fee).
When using an external power supply, do not exceed the rated voltage of the device,
otherwise it will cause damage to the device.
Please turn off the power immediately when the machine shell is very hot near the
battery, and put the equipment in a safe and ventilated place. After confirming the
safety situation, please contact us for proper handling.

3.5 Adjust the volume
Adjust the output volume according to the volume plus and minus buttons.
When using the AF- IN/OUT port of the ACC interface, please adjusting the volume level
in the system menu.
3.6 Regulated transmit power
Press the [Po] transmit power setting button, you can set the transmit power.
A. Press the [Po] button to enter the power setting state, the screen will display the Po
power setting number.

19
3.8 Set operating frequency
There are two ways to set the X5105 operating frequency, use the big knob to set the
frequency, or use the multi-function mic to set the frequency.
Operation method:
A. Use large knob to set frequency
Press the button [<] or [>], move the cursor of the frequency bit to the left or to the
right, select the frequency of the desired step.
Rotating frequency knob sets the frequency of the current step.
B. Use a multi-function microphone for frequency setting
Press the [F-INP ENT] button on the cursor, and the X5105 enters the frequency setting.
The cursor appears on the left of the frequency display bit.
Enter the desired frequency value in turn, and then press [F-INP ENT] button again to
complete the frequency setting.
For example, set the current frequency to 51.050000MHz, and press the order as
follows:
First, press the [F-INP ENT] button.
Please press the 51.050000 numeric key in turn.
Once again press the [F-INP ENT] button to complete the settings.
3.9 Start the ATU (automatic antenna tuner) into the tuning function
X5105 transceiver built-in an efficient automatic antenna tuner, which can help you easily
complete the erection and debugging of the antenna.
Press the [ATU] button shortly to access the built-in tuner and the "TUNE" logo appears
on the top of the screen.
Press the [ATU] button for a long time, it will start the ATU auto tuning function. When
the tuning is complete, the host will automatically return to the receiving state.
3.10 RIT (receive frequency trimming)
Relative to the set frequency, the RIT function can set the offset value of the actual
In actual operation, if the [HI-SWR] icon flashes on
the screen, the tuning fails, and the SWR is large
and needs to be tuned again.

20
receiving frequency of the maximum ±1.5kHz.
Operation method:
A. Press [RIT] button to start RIT function.
B. The rotating knob can change the receiver frequency in the range of ±5kHz. The
screen has the corresponding area to display the frequency change value.
C. If you want to clear the RIT offset, press [RIT] button for about 2 seconds, in the
system prompt tone "beep" sound, the value of RIT settings will be cleared.
If the frequency offset range more you want, you can use split frequency transceiver
mode. Please refer to the VFO instructions for details.
3.11 Automatic gain control (AGC)
By adjusting the appropriate AGC automatic gain control speed, the receiver can achieve
the best effect. Operation method:
A. Switch to the second page menu, press [AGC] function button shortly.
B. The AGC function will be selected in the following order:
When you select "AGC-AUTO", the CW mode is actually "AGC-FAST", in voice mode is
"AGC-SLOW."
If AGC-OFF is selected, the AGC system is turned off and the display of the S table is
stopped.
3.12 Preamplifier / preamplifier (PRE/ATT)
Pre amplifier (PRE) and pre attenuator (ATT) can improve the receiver's listening effect.
When the signal is weak, the preamplifier can be switched on to increase the signal
strength. When the signal is strong, the preamplifier can be switched on to reduce the
signal strength.
Of course, you can also choose to turn off the circuit unit so that the signal will by pass.
Operation method:
A. Press the [PRE/ATT] button to start the function.
B. The switching sequence will follow the following loop:
In the low frequency waves (less than 10MHz) operation, the preamplifier can be closed,
then let signal in by-pass state, it will be more conducive to improve the receiving effect,
