1
Green LED: Indicates that the compressor is working.
2
Yellow LED: indicates that the external power supply is
present (voltage is higher than 13.5 V or 27.0 V).
The LED flashes if the external power supply is too low
(voltage ≤ 10.7 V or 21.7 V. Version E: ≤ 10.7 V or 22.0 V).
3
Red LED: indicates that the accumulator is being discharged
because
4
Accumulator discharge button: interrupts compressor
operation until
5
Temperature selector: allows the temperature in the cooling
area to be set as required
Min. (left limit) = warmest setting
Max. (right limit) = coldest setting
6
Main switch: for switching the cooling device on and off.
Position 0 = OFF
Position - = ON
48
the discharge button has been pressed
Low voltage shutdown (voltage ≤ 10.7 V or 21.4 V. Version
E: ≤ 10.7 V or 22.0 V).
the stored cold energy is exhausted
The external supply voltage level is restored after
low voltage.
