Frequently Asked Questions
Q: Can the Mover® SR be used on tandem-axle caravans?
No, the Mover® SR is exclusively suitable for single-axle caravans.
Q: How far should the disengaged drive rollers sit from the tyres?
The gap between the tyres and disengaged drive rollers needs to be exactly 20mm.
Q: How do I synchronise the remote handset with the electronic control unit?
Hold the control unit's reset button until the red LED flashes rapidly (around 5 seconds), release it, then within 10 seconds hold the remote handset's caravan reverse button while switching the handset on with its slide switch.
