IVOLTAGE PROTECTION MODE:
The device has three battery protection functions, which protect the normal operation of the refrigerator and protect the battery of the vehicle.
The three levels of battery protection are:
H3 – high level:
for voltage 12V: stops at 10.9V and starts operation at 12.2V
for voltage 24V: stops at 23.8V and starts operation at 25.2V
H2 – medium level:
for voltage 12V: stops at 9.7V and starts operation at 11.0V
for voltage 24V: stops at 21.5V and starts operation at 22.9V
H1 – low level:
for voltage 12V: stops at 9.6V and starts operation at 10.9V
for voltage 24V: stops at 21.3V and starts operation at 22.7V
Short press the “+” or “-” button to choose the function. The function is set at “H2” medium level when the refrigerator is ready for first use.
NOTE:
It is recommended to set the battery protection at H2 (medium level) when the device is used in the car.
It is recommended to set the battery protection at H2 (medium) or H1 (low) if it is an external battery or backup battery.
Because of the difference in voltage output from different vehicle power supply output, if there is voltage protection (LCD display shows F1), the battery function could be reduced to a lower one (H3 is adjusted to H2 or H1).
