Standard voltage input range: DC12V/24V, up to DC30V
1. Open and close the refrigerator:
Connect the correct DC12/24V power supply. If the refrigerator is in standby
state, the "OFF" symbol will appear in the middle of the display after the refrig-
erator self-test is completed. At this time, you need to press and hold the
"Power button" for 3 seconds to complete the startup. After the refrigerator is
turned on, the display will show the current temperature and working mode of
the refrigerator. After waiting for the power-on delay (the factory default is 1
minute), the refrigerator enters the working mode, and the compressor starts
to work to cool down. To turn off the refrigerator, press and hold the "Power
button" for 3 seconds while the keyboard is unlocked.
2. Refrigerator keyboard locking and unlocking operations:
For example, when the keyboard is locked (the child lock icon is on in the lower
right corner of the display screen), long press the "UP/DOWN" button for 3
seconds to unlock, the child lock icon will not light up, and the keyboard will be
locked automatically if there is no operation for 30 seconds.
3. Compressor working mode setting:
In the unlocked state of the keyboard, press the "Set button" to freely switch
the compressor working mode "ECO/MAX", if you need to quickly cool down to
a lower temperature, switch to "MAX" mode, if you only need to refrigerate or
keep warm, you can set the It is set to "ECO" mode to save energy.
4. Low voltage protection function setting:
This product has a low voltage protection function. When it detects that the
battery voltage is lower than the set value, it will automatically turn off the

compressor to prevent over-discharge from damaging the battery or causing
the car to fail to start normally. At this time, the "EI" code prompt will be
displayed on the display screen, such as 1 minute after the voltage returns to
normal, the refrigerator will automatically enter the working state. The factory
default is "Mid-Range", if you need to change it, follow the steps below:
a： Unlock the keyboard
b: Press and hold the "Set button" for 3 seconds, release it after hearing the
"di" sound of the buzzer, and then briefly press the "Set button" again, and
one of the battery protection level icons "L, M, H" on the display will flash.
Display and then press the "UP/DOWN" to change the setting. Refer to the
following table for specific values:
battery protection 12V disconnect
L 9.6 V
M 10. 4 V
H 11.1 V
Note: If your refrigerator enters battery protection early, it is likely that the low
voltage protection value is set too high due to insufficient power supply
voltage. Or your DC power supply is wired incorrectly and cannot provide
enough current. Check whether the power wiring is suitable, and consider
lowering the battery protection gear appropriately. In order to ensure that the
car can be started normally, it is recommended to set the protection level to
"H" when using the refrigerator in the car.
