4.2.1. Rotation Lock/Safety Lock
This button controls two functions: rotation lock and safety lock mode. The rotation lock is the primary function. The chair
may be manually rotated 345° on its base. The chair is normally in the locked position. To unlock the brake, press the
button for 1 second. Once unlocked, the chair will be free to rotate to the desired position. The button can be pressed for
1 second again to set the brake or the chair will automatically secure the rotational lock after a 12 second delay.
The safety lock mode is also activated using this button. This function sets the rotation lock on the chair and disables
the key pad controls and optional footswitch controls. While in safety lock mode, the padlock indicator light will be lit. To
activate the safety lock mode, press the lock button and hold for at least 3 seconds. The padlock indicator light will light
up once the safety lock mode is entered. To exit safety lock mode, press the lock button again and hold for at least 3
seconds. The padlock indicator light will extinguish once the safety lock mode is exited.
4.2.2. Backrest Up
This button moves the chair back from a reclined position to an upright position. The chair back will move up for as long
as the button is pressed until it reaches its travel limit of 80° above horizontal.
4.2.3. Backrest Down
This button moves the chair back from an upright position to a reclined position. The back will move down for as long as
the button is pressed until it reaches its travel limit of horizontal.
4.2.4. Seat Up
This button moves the chair up in elevation. The chair will move up for as long as the button is pressed until it reaches its
travel limit of 38” from the floor. If the rotation lock is unlocked while the chair is moving up, the seat will pause for one
second then resume moving up.
