These units are mounted on the frame of the vehicle in the
immediate vicinity of the wheels, and are connected by lateral
bars.
Once the drive rollers have been engaged using the lever pro-
vided, the manoeuvring assistant is ready for operation. It is
operated exclusively via the remote control, which transmits ra-
dio signals to the control unit. A separately installed 12 V lead-
acid battery or suitable lead-gel battery (not supplied) provides
the control unit with electrical power.
Operating instructions
Remote control
a = On / Off slide switch
❙
On (green LED lights up)
Off (green LED goes off)
b = caravan forwards
(both wheels rotate in forward
direction)
c = caravan reverse
(both wheels rotate in reverse
direction)
d = caravan right forwards
(left wheel rotates in forward
direction)
e = Caravan left forwards
(right wheel rotates in forward
direction)
f = Caravan right reverse
(left wheel rotates in reverse direction)
g = Caravan left reverse
(right wheel rotates in reverse direction)
The caravan can be rotated on the spot without being moved
forwards.
d + g = rotate caravan to the right
(left wheel rotates in forward direction + right wheel
rotates in reverse direction)
e + f = rotate caravan to the left
(left wheel rotates in reverse direction + right wheel
rotates in forward direction)
The remote control will switch itself off after about 2 minutes if no
buttons are pressed, or after about 7 minutes if one of the move-
ment buttons is pressed continuously. The green LED goes off.
To reactivate the remote control, move the slide switch to
"Off"
and then back to "On"
There is no "On / Off" switch on the caravan itself.
Remote control LED blink code and audio signal
LED "on" and no audio signal
System is ready for use
LED "off" and no audio signal
System off
(check batteries in remote control if necessary)
LED "flashing" in combination with audio signal:
– for approx. 5 seconds after switching the remote control on,
until the system is ready for operation
– for approx. 10 seconds after switching the remote control on,
then it is switched off again – unable to establish radio link to
control unit.

RH 1 Manoeuvring Assistant
– every 3 seconds if the caravan battery charge is weak (finish
manoeuvring as quickly as possible and charge battery).
– 5 times a second (5 Hz) if the caravan battery voltage is low.
The movement function is locked until battery voltage returns
to more than about 11 V (e.g. as a result of recovery / charg-
ing of the battery).
– approx 2 times a second (2 Hz) in the event of overvoltage /
overtemperature. Switch remote control off and on again (in
the case of overtemperature, wait for end of cooling-off phase
if necessary).
Remote control battery change
Only use micro-batteries that will not leak,
type LR 03, AAA, AM 4, MN 2400 (1.5 V).
When inserting new batteries pay
attention to plus / minus!
Empty, used batteries can leak and
damage the remote control!
Remove the batteries if the remote control
is not being used for a long period of time.
No warranty is given for damage caused by leaking
batteries.
Before scrapping a defective remote control, always remove
the batteries and dispose of them properly.
Manoeuvring the caravan
Follow the "Safety instructions" before using the
manoeuvring assistant.
With the caravan uncoupled (apply parking brake), engage the
drive rollers using the lever provided. Turn the lever until it can-
not be turned any further without excessive force. In the end
position the drive assembly engages securely.
Take care to prevent fingers from being trapped when
engaging / disengaging.
Before starting the manoeuvring assistant, release the
parking brake.
Move slide switch (a) on remote control to the "On" position
– green LED flashes in combination with the audio signal for
approx. 5 seconds until the control unit is ready for use.
The direction buttons allow the caravan to be moved in
six directions – forwards, reverse, left forwards, left reverse,
right forwards, right reverse.
In addition, the "left forwards" (e) and "right reverse" (f), or
"right forwards" (d) and "left reverse" (g) buttons can be
pressed simultaneously to turn the caravan on the spot without
moving it forwards.
The Softstart / Softstop makes the caravan start to move
without jolting, and brakes it gently when stopping.
When the buttons are released, or if the radio signal is inter-
rupted or becomes too weak, the caravan stops moving. Radio
equipment and other manoeuvring assistant remote controls
will not activate your manoeuvring assistant.
After starting up, the manoeuvring assistant moves at a uni-
form speed. Speed increases slightly on downhill slopes and
decreases on uphill slopes.
