Blue 9V bat t ery LED: The int ernal 9V bat t ery of handset is near em pt y and needs t o be replaced
K. Blue bat tery voltage LED: Caravan batt ery voltage too low or too high
When you drive st raight forwards or reverse ( press but t on B or C) , it is also possible to adj ust the direct ion by
addit ional pressing but ton D or E ( when driving forwards) or but t on F or G ( when driving reverse) .
I n addit ion, t he ‘right forward’ ( E) and ‘left reverse’ ( F) buttons or ‘left forward’ ( D) and ‘right reverse’ ( G)
but t ons m ay be pressed at t he sam e t im e t o t urn t he caravan around on it s own axis wit hout m oving forward or
backward (
t his funct ion j ust can w ork under t he “ single- ax le funct ion” ) .
When you swit ch wit hin 2 seconds from forward driving t o reverse driving ( and t he other way around) , a sm all
delay of 1 second will appear to protect the electronics and the m otors.
The slide sw it ch ( Fig. 5 A) also act s as a n “Em ergency st op”.
The r em ot e hand set sw it ches off:
Aft er 3 m inut es, if no but t on is pressed: Aft er 2 m inut es t he buzzer will beep for 5 t im es wit h a repet it ion
after 3 m inutes. Than t he system switches in t he “ stand- by” m odes.
After 6 m inutes, if one of the m ovem ent buttons is perm anently held down: Aft er 5 m inut es the buzzer will
beep for 5 t im es wit h a repet it ion aft er 6 m inut es. Than the system swit ches in the “ stand- by” m odes.
The green LED goes off and t he rem ot e cont rol handset is in t he “ stand- by” m odes which m eans that t here
always will be used som e current which causes the bat tery to go down. So always m ake sure t he rem ote
control handset is turned off by the slide swit ch.
To react ivat e t he rem ot e cont rol, m ove slide switch to “ Off” –O and then back t o “ On” - I aft er approxim at ely 1
second.

m anoeuvring syst em will be com m unicat ed via the rem ote control
handset by the green LED ( Fig. 5H) , the error m essage LED’s ( Fig. 5I , 5J & 5K) and a buzzer signal:
Green LED ( Fig. 5H) off, no buzzer: rem ot e cont rol handset is turned off and also system is not act ivated
Green LED ( Fig. 5H) cont inue on, no buzzer: rem ot e control handset is turned on and system is activated
and ready t o use.
Green LED ( Fig. 5H) is blinking, no buzzer: no com m unication between handset and control unit . This could
be because of too m uch distance between rem ote control handset and control unit, or the batt ery isolation
swit ch for m anoeuvring syst em is not turned on or that there is a distortion signal disturbing t he
com m unicat ion. As soon as connect ion is good again the green LED will be continue on and the system is
ready t o use.
Blue bat tery voltage LED ( Fig. 5K) is blinking in com binat ion with buzzer ( 2 tim es blinking, break, 2 tim es
blinking, break etc.) : Batt ery voltage too low ( < 10V) . Bat t ery needs to be recharged.
Blue bat tery voltage LED ( Fig. 5K) is blinking in com binat ion with buzzer ( 4 tim es blinking, break, 4 tim es
blinking, break etc.) : Batt ery Volt age too high ( over charged) . Try t o discharge t he bat t ery by t urning on a
user ( for exam ple a lam p or wat er- pum p) .
Red overload LED ( Fig. 5I ) is blinking in com bination with buzzer ( 6 t im es blinking, break, 6 tim es blinking,
break et c.) : Am p overload prot ection is activat ed. Wait about 60 seconds and t ry again.
Blue 9V bat t ery LED ( Fig. 5J) is blinking, no buzzer: The internal 9V bat tery is near em pty and needs t o be
replaced.
Changing bat t eries in t he rem ot e cont rol:
When t he batt ery is em pty ( blue 9V batt ery LED ( Fig. 5J) is blinking) , it needs to be replaced.
Open t he rear cover of t he handset ( Fig. 7A) .
Take out t he dead/ old bat tery and dispose in t he appropriat e way.
I nst all a new replacem ent battery ( Fig. 7.1) . Make sure t o use a leak proof PP3 ( 9Volt ) bat t ery ( No claim s
under guarant ee can be considered for dam age caused by leaking bat t eries) .
Close t he rear cover again.
