LiNX® Control System
Contact your Invacare provider for more information
about maintaining and troubleshooting the Sip and
Puff system.
For further maintenance and cleaning instructions,
see 7 Maintenance, page 109 .
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 8.2 OON ("Out Of Neutral"), page114 .

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 screens for the Sip and Puff Head Array
are pre-set in latched driving mode. For more information,
refer to 6.6 Latched driving mode, page 45.
1. Puff into mouthpiece A to drive forward.
2. Sip at mouthpiece A to drive in reverse.
3. When in latched driving mode, activate left pad B to
veer to the left.
4. When in latched driving mode, activate right pad C
to veer to the right.
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 input all the time, but the mouthpiece
