on in most vehicles to apply

When operating from the
12/24-V socket (cigarette ligh-
ter): The ignition is on and the
device is not working and the
LED is not lit. Pull the plug out
of the socket and make the fo-
llowing checks.
The cigarette lighter socket
is dirty. This results in a poor
electrical contact. If the plug of your cooler be-
comes very warm in the ciga-
rette lighter socket, either the
lighter socket must be clea-
ned or the plug has not been
assembled correctly.
The fuse of the 12/24 V plug
has blown. Replace the fuse(10A) in the
12/24 V plug, see “ Replacing
the plug fuse(12/24 V)”.
The Vehicle fuse has blown. Replace the vehicle’s 12/24 V
socket fuse(usually 15 A).
