Sip and Puff is not the most manoeuvrable or intuitive control method and therefore requires a considerable amount of training. In the
early tuning stages, this is best done outdoors in an unrestricted but safe area. Also the presence of an attendant is recommended.
Inside the Head Array pads, there are proximity sensors, that allow you to steer the wheelchair in the desired direction with the movement of your
head. This means that the head does not need to touch the pads or press a switch to activate driving. If the head comes within 6 mm of a sensor,
the sensor is activated and the wheelchair starts driving.
By default, the Head Array powers up as soon as the wheelchair is powered up and powers down as soon as the wheelchair is powered down.
Be aware, that when powering up automatically with the wheelchair, your head has to be more than 6 mm away from the proximity
sensors, otherwise a drive OON warning is displayed and prevents the wheelchair from driving. For more information about OON, refer to
6.2 OON ("Out Of Neutral"), page 93.
Driving
This component combines simple sip and puff controls with head movements. Right and left turns are controlled by sensors located in the pads of
the Head Array.
The drive function cards for the Sip-N-Puff are pre-set in latched driving mode. For more information, refer to 4.10 Latched Driving Mode, page 37.

To revolve, you only need to activate left or right pad.
Stopping
A lipswitch D is mounted to the mouthpiece. This switch can be used as an external stop switch, when in latched driving mode. While you are in
latched driving, you do not need to give a drive demand all the time, but the mouthpiece must stay inside your mouth. As soon as the lipswitch is
pressed while driving, the wheelchair stops.
