OPERATION - REMOTE CONTROL HANDSET
The remote control handset (31) is powered by one PP3 9Volt battery, and is activated by moving the slide
switch to “On”-I (Fig. 5A). Once activated the green LED (Fig. 5H) will illuminate and the directional controls
can now be used.

Blue battery voltage LED: Caravan battery voltage too low or too high
When you drive straight forwards or reverse (press button B or C), it is also possible to adjust the direction by
additional pressing button D or E (when driving forwards) or button F or G (when driving reverse).
In addition, the ‘right forward’ (E) and ‘left reverse’ (F) buttons or ‘left forward’ (D) and ‘right reverse’ (G)
buttons may be pressed at the same time to turn the caravan around on its own axis without moving forward or
backward (this function just can work under the “single-axle function”).
When you switch within 2 seconds from forward driving to reverse driving (and the other way around), a small
delay of 1 second will appear to protect the electronics and the motors.
The slide switch (Fig. 5A) also acts as an “Emergency stop”.
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.
Error messages via the remote control handset:
Error messages of the EN
DURO
®
EM303 manoeuvring system will be communicated via the remote control
handset by the green LED (Fig. 5H), the error message LED’s (Fig. 5I, 5J & 5K) 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. 5K) 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. 5K) 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. 5I) 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. 5J) 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. 5J) 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.
