When the chair is operated in the memory/automatic mode, all operation switches on the operation panel (switch group I for chair operation, switch group II for instruments, and switch group III for spit, vacuum) are set to emergency stop switches, and the movement of the chair is stopped after any switch is pushed.</p> |
