Troubleshooting / Cleaning and maintenance
Problem
Possible cause
Solution:
The fuse in the device
has blown.
Replace the fuse,
as described in the
“Replacing the fuses”
chapter. Make sure that
the car power inverter
1
is connected to the
power supply using the
right polarity.
Televisions:
The car power inverter
1
is screened and outputs a
modified sine wave.
However if reception from
television channels is extremely
weak, this can lead to interfer-
ence or picture distortion.
In this case, position the car
power inverter
1
as far from
the television, aerial cable and
aerial as possible.
Align the car power inverter
1
, television, aerial cable and
the to one another, until the
reception improves.
If possible, use a high-quality,
screened aerial cable.
Audio systems:
Some audio/video systems
emit a humming noise through
the speaker when they are
operated using the car power
inverter
1
.
This is due to the fact that
these devices cannot filter the
modified sine wave of the
car power inverter
1
and is
not a defect of the car power
inverter
1
.
