C. THERMAL ROLL-BACK

Your chair has a thermal roll back circuit. This protects the controller from damage due to overheating. In extreme conditions (such as repetitive hill climbing) the circuit will decrease the power to your motors.

This allows the chair to operate at a reduced speed.When the controller cool, the chair will return to normal speed.

D. CIRCUIT BREAKERS

1. Notes:

Your Quickie V-521 has two styles of battery box; Single (one circuit breaker) and Dual (two circuit breakers, one on each box)

In the unlikely event of a short circuit or heavy overload, all power to your chair will be shut off.

To reset your chair, depress the circuit

breaker button(s) on the battery box lids. A few minutes wait is required before the circuit breaker(s) will reset.

2. Repeated Shutdown:

If the chair continues to shut down after resetting, have it serviced by a supplier.
