The slide switch (Fig. 5A) also acts as an “Emergency stop”.
The automatic engaging system:
To activate the automatic engaging system of the motor powered rollers on the tyre, press the two buttons for
engaging (Fig. 5I) or disengaging (Fig. 5J) for at least three seconds. The blue LED (Fig. 5K) will blink fast
during these three seconds and every second there will be a beep. This warns you that the system will be
activated!
Engaging: After these three seconds the motor powered rollers will be pressed against the tyre, and the blue
LED will illuminate constant. Now you can release the two buttons. When the motor powered rollers are pressed
on the tyre strongly enough you hear a short beep, the blue LED will switch off and the system is ready to use.
Disengaging: after these three seconds the motor powered rollers will be released from the tyre, and the blue
LED will illuminate constant. Now you can release the two buttons. When the motor powered rollers are
completely disengaged you hear a short beep, the blue LED will switch off and is the system ready for transport.
The remote hand set switches off:
After 3 minutes, if no button is pressed: After 2 minutes the buzzer will beep for 5 times with a repetition
after 3 minutes. Than the system switches in the “stand-by” modes.
After 6 minutes, if one of the movement buttons is permanently held down: After 5 minutes the buzzer will
beep for 5 times with a repetition after 6 minutes. Than the system switches in the “stand-by” modes.
The green LED goes off and the remote control handset is in the “stand-by” modes which means that there
always will be used some current which causes the battery to go down. So always make sure the remote
control handset is turned off by the slide switch.
To reactivate the remote control, move slide switch to “Off” –O and then back to “On”-I after approximately 1
second.

will be communicated via the remote control handset by the green
LED (Fig. 5H), the error message LED’s (Fig. 5L, 5M & 5N) and a buzzer signal:
Green LED (Fig. 5H) off, no buzzer: remote control handset is turned off and also system is not activated
Green LED (Fig. 5H) continue on, no buzzer: remote control handset is turned on and system is activated
and ready to use.
Green LED (Fig. 5H) is blinking, no buzzer: no communication between handset and control unit. This could
be because of too much distance between remote control handset and control unit, or the battery isolation
switch for manoeuvring system is not turned on or that there is a distortion signal disturbing the
communication. As soon as connection is good again the green LED will be continue on and the system is
ready to use.
Blue battery voltage LED (Fig. 5N) is blinking in combination with buzzer (2 times blinking, break, 2 times
blinking, break etc.): Battery voltage too low (<10V). Battery needs to be recharged.
Blue battery voltage LED (Fig. 5N) is blinking in combination with buzzer (4 times blinking, break, 4 times
blinking, break etc.): Battery Voltage too high (over charged). Try to discharge the battery by turning on a
user (for example a lamp or water-pump).
Red overload LED (Fig. 5L) is blinking in combination with buzzer (6 times blinking, break, 6 times blinking,
break etc.): Amp overload protection is activated. Wait about 60 seconds and try again.
Blue 9V battery LED (Fig. 5M) is blinking, no buzzer: The internal 9V battery is near empty and needs to be
replaced.
Changing batteries in the remote control:
When the battery is empty (blue 9V battery LED (Fig. 5M) is blinking), it needs to be replaced.
Open the rear cover of the handset (Fig. 7A).
Take out the dead/old battery and dispose in the appropriate way.
Install a new replacement battery (Fig. 7.1). Make sure to use a leak proof PP3 (9Volt) battery (No claims
under guarantee can be considered for damage caused by leaking batteries).
Close the rear cover again.
Dead and used batteries may leak and damage the remote control handset! Remove the batteries if the
handset is not going to be used for an extended period.
OPERATION – ELECTRONIC CONTROL UNIT
The electronic control unit (4), which is mounted inside your caravan, is responsible for controlling the
manoeuvring system.
The control unit has three LED’s, one pushbutton and one slide switch (Fig. 3):
Green LED (Fig. 3B): Power LED continuously illuminated
when system is activated (by moving slide switch to
“On”-I). If the handset far away from the control unit, beyond the availably distance, this LED will go out.
Blue LED (Fig. 3C): Error message LED concerning caravan battery:
