WARNING!
Risk of Injury or Damage
Improper mounting or maintenance of the Sip and
Puff control, including the mouthpiece and breath
tube, may cause injury or damage.
Water inside the Sip and Puff interface module may
cause damage to the unit.
Excessive saliva residue in the mouthpiece/straw can
reduce performance.
Blockages, a clogged saliva trap or air leaks
in the system may cause the Sip and Puff
not to function properly.
-Ensure moving parts of the wheelchair, including the
operation of powered seating, DO NOT pinch or
damage the Sip and Puff tubing.
-Saliva trap MUST be installed to reduce risk of water
or saliva entering the Sip and Puff interface module.
-Occasionally flush the mouthpiece to remove
saliva residue.
-The mouthpiece/straw MUST be completely dry
before installation.
-If Sip and Puff does not function properly, inspect
system for blockages, clogged saliva trap or air leaks.
As necessary, replace mouthpiece, breath tube and
saliva trap.
Contact your Invacare provider for more information
about maintaining and troubleshooting the Sip and
Puff system.
For further maintenance and cleaning instructions, see
Maintenance, page 1.
Sip and Puff is not the most maneuverable 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 displays and prevents the wheelchair
from driving. For more information about OON, refer
to 8.2 OON ("Out Of Neutral"), page 90.

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
preset in latched driving mode. For more information, refer to
6.6 Using Latched Driving Mode, page 43.
1. Puff into the mouthpiece A to drive forward.
2. Sip at the mouthpiece A to drive in reverse.
3. When in latched driving mode, activate the left pad B to
veer to the left.
4. When in latched driving mode, activate the right pad C to
veer to the right.
To revolve, you only need to activate the 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 mode, you do not need to give
a drive input all the time, but the mouthpiece must stay inside
your mouth. As soon as the lipswitch is pressed while driving,
the wheelchair stops.

Changing Function Screens

The lipswitch can also be used as a mode function switch.
For the difference between a function screen
and profile, refer to 4.3 User Function Screen
Overview, page 13.
1. Stop the wheelchair.
2. Short press the lipswitch to change the function screen.
3. Long press the lipswitch to change the profile.
Seating functions can only be operated with the right
or left pad of the head array.
