6.4 USING THE BATTERY MONITOR

The device is equipped with a multi-level battery monitor that protects your vehicle battery against excessive
discharging when the device is connected to the on-board 12/24 V supply.
If the cooler is operated when the vehicle ignition is switched off, the cooler switches off automatically as soon
as the supply voltage falls below a set level. The cooler will switch back on once the battery has been recharged
to the restart voltage level.
NOTICE! Danger of damage!
When switched off by the battery monitor, the battery will no longer be full charged.
Avoid starting repeatedly or operating current consumers without longer charging phases.
Ensure that the battery is recharged!
In »HIGH« mode, the battery monitor responds faster than at the levels »LOW« and »MED«
(see the following table)
Battery monitor mode
Switch-off voltage at 12 V
Restart voltage at 12 V
Switch-off voltage at 24 V
Restart voltage at 24 V
The battery monitor mode can be selected as follows:
• Switch on the cooler.
• Press the »SET« button (Abb. 3/4) three times.
• Use the »UP+ (Abb.3/6) or »DOWN-« (Abb. 3/7) buttons
to select the battery monitor mode.
• IDigital display will be as follows: Lo (LOW), Md (MED), Hi (HIGH)
✓ The selected mode then appears in the display for a few seconds. The display
flashes several times before it returns to the current temperature.
NOTE
When the cooler is supplied by the starter battery.Select the battery monitor mode »HIGH«.
If the cooler is connected to a supply battery, the battery monitor mode »LOW« will suffice.

6.5 USING THE FREEZER

NOTICE! Danger of overheating!
Ensure at all times that there is sufficient ventilation so that the heat that generated during operation can
dissipate. Ensure that the ventilation slots are not covered. Make sure that the device is sufficiently far away
from walls and other objects so that the air can circulate. Make sure that the ventilation slots are not covered
and that the heated air can dissipate.
Place the Freezer on a firm foundation.
Make sure that the ventilation slots are not covered and that the heated air can dissipate.
