6.8 Selecting the temperature unit
See fig. 1, page 7
You can switch the temperature display between Celsius and Fahrenheit. To do this,
proceed as follows:
➤ Switch on the cooler.
➤ Press the “SET” button (4) twice.
➤ Use the “+” (6) or “–” (7) buttons to set the temperature unit °Celsius or
°Fahrenheit.
✓ The selected temperature units then appear in the display for a few seconds. The
display flashes several times before it returns to the current temperature.
6.9 Using the battery monitor
A
The cooling device is equipped with a multi-level battery monitor that protects your
vehicle battery against excessive discharging when the device is connected to the
vehicle DC 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 the set level. The cooler
will switch back on once the battery has been recharged to the restart voltage level.
I
In HIGH mode, the battery monitor responds faster than at the levels “LOW” and
“MED” (see the following table).
NOTICE! Beware of damage
When switched off by the battery monitor, the battery will no longer be
fully charged. Avoid starting repeatedly or operating electric consumers
without longer charging phases. Make sure that the battery is
recharged.
NOTE
When the cooling device is switched off by the battery monitor due to
low voltage, the display (fig. 1 5, page 7) switches off and the “Power”
LED (fig. 1 2, page 7) flashes orange.
