Extremely low power consumption (< 0.007 A)
Switches off automatically when the battery voltage < approx. 11.1 V ± 0.3 V (battery monitor).
Also suitable for cars with a CAN bus. Also suitable for hybrid vehicles.
Soft start –without influencing on-board electronics
An intelligent soft start circuit activates our modules slowly at a very low power consumption level. Even the
latest highly sensitive on-board computers do not record our modules as consumers in this context. In
contrast to devices with a “hard” start-up and current pulses of up to 25 mA, our modules do not generate
error messages. Battery management systems (BMS) or hybrid vehicles also pose no difficulty for us.

Temperature range: approx. -25...+80 degrees C
Function display: 2 flashing LEDs for ultrasound and high voltage (for scaring and function control)
Dimensions of control device: approx. 86 x 55 x 50 mm, cable length of high voltage cable: approx. 4 m (±
10%)
Fuse in fuse holder: Mini 1 A (or 2 A) blade-type fuse
Multi-contact high-voltage brushes with positive + negative legs: 6 pieces movable high-voltage brushes.
Also suitable for vehicles with CAN bus.
Automatic reduction of power consumption in the case of short-circuit or contamination (reactive currents)
at the high-voltage brushes.
Impulse withstand voltage: approx. 40 V 2 mSec
Compact plug-and-socket connection at control device for simple disconnection of the control device from
the cable installation.

Available accessories (not included):
Extension kit, article M4700B-kit –4 additional contact brushes for large engine compartments.
Proper use:
To scare martens and other wildlife from the engine compartments of vehicles using electric shocks,
pulsating light and aggressive, pulsating ultrasonic frequencies.
Disposal:
If the devices have to be disposed of, then they should not be placed with domestic refuse. They must be
delivered to collection points for televisions, computers, etc. (please ask your local authority or town council
for the location of these electronic disposal points). Disposal in accordance with the national regulations.
Ultrasonic sound extends like light; there are “shadows” cast behind obstacles (no ultrasonic sound). The
loudspeaker in the device should therefore radiate towards the areas at risk of being bitten. The ultrasonic
sound reaches all points that are visible from the loudspeaker dome in the engine compartment.
Fitting instructions:
During assembly, please take the fuse of the device from the fuse holder. The base device is installed at a
point in the car where it is not too hot (please don‘t install it directly adjacent to the exhaust manifold or
other hot area). The positive cable with the fitted fuse holder is connected to “+12 V”.
The earth cable is connected to the vehicle earth or “-12 V”.
The engine bonnet switch or “short-circuiting switch” immediately discharges the high-voltage brushes
when the engine bonnet is opened (for maintenance work). This can be connected to any brush contact
plate but always on the positive pole of the high-voltage cable (flat lateral contact stud). However, you can
also take the mini blade-type fuse out of the fuse holder by hand and then wait approx. 1 minute until the
high voltage has dissipated in order to then carry out maintenance work with the marten scarer switched off.
Or you can disconnect the compact plug connection. The marten scarer is then immediately switched off
