The lower legs are supported by a strap, which holds the ankles tightly against the chair:
Never release the horizontal axis unless the patient is held by all four
supporting devices, which must be correctly adjusted.
1. Four-point harness.
2. Shoulder supports.
3. Head support with properly tightened head strap.
4. Leg strap.
To release the axle, press the foot switch. When the green lights on both sides of the primary frame are
on, the magnetic locking system will be released by a slight pull or push of the primary frame.
The vertical axle is released by pulling the lock button downwards. It is automatically brought back to the
locked position by a return spring.
To keep the vertical axle permanently unlocked for barbecue maneuvers etc., pull the button to its fully
down position and give it a quarter-turn left or right to prevent it from returning to the locked position. On
older versions of the TRV, use the lock at the front for the diagnostic and therapeutic maneuvers and the
lock on the left side for the standard position and while the patient is being secured in the chair.
