1. Functionality
The variable marten car defence generates an
acoustic signal with a frequency of 12 – 23 kHz
in intervals of each 15 seconds turn-on and
turn-off time. This ultra high frequency is
sensed by the martens and mice as perturbing
and nasty, so that they flee from the corres-
ponding vehicle.
2. Assembly
The variable marten car defence is fastened
by means of self-tapping screws or binders in
the engine compartment on the carriage. The
connecting cable to the car battery must be
passed in that manner that it doesn’t get in
contact with movable or hot parts (e.g. ven-
tilating wheel, exhaust manifold). The device
should be placed in the engine compartment
in that manner that the acoustic noise can
constantly spread and is not absorbed by in-
sulating mats.
Attention! The assembly should be
carried out by authorised specialised
staff!
3. Electrical connection
The device is directly connected to the car
battery. The black cable is connected to the
positive pole, the brown one to the negative
pole. If additionally the grey cable is connected
to clamp 15 (ignition lock, car radio) of the car
battery, the control automatically switches on
the device, when the ignition is turned off and
automatically switches it off, when the ignition
is switched on. This increases the durability of
the device, as it is only put into operation with
the motor turned off.
