All other control components are under batteries, in the event of a power failure of motor
check to make sure connections are tight. The ISM controls the actuators for positioning if
your chair is not equipped with a 3-switch system. If the chair will not stand or positioning
systems fail try a re-set by disconnecting the main power several times at the circuit
breaker. If the component is defective and the chair will not stand to access the ISM
remove the seat pan to access.
