Dometic CFX Series Operating Manual page 16

Operation
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
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 a set level. The cooler will
switch back on once the battery has been recharged to the restart voltage level.
A
When switched off by the battery monitor, the battery will no longer be
fully 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).
The battery monitor mode can be selected as follows:
➤ Switch on the cooler.
➤ Press the "SET" button (fig. 3 4, page 2) four times.
➤ Use the "UP +" (fig. 3 10, page 2) or "DOWN –" (fig. 3 9, page 2) buttons to
select the battery monitor mode.
✓ Digital display will be as follows:
Lo (LOW), Ed (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.
I
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.
