CAUTION!
Risk of Injury or Damage
Improper mounting or maintenance of the
Sip-N-Puff control including the mouthpiece and
breath tube may cause injury or damage.
Water inside the Sip-N-Puff interface module may
cause damage to the unit.
Excessive saliva residue in the mouthpiece can
reduce performance.
Blockages, a clogged saliva trap or air leaks in
the system may cause Sip-N-Puff not to function
properly.
– Ensure moving parts of the wheelchair,
including the operation of powered seating, DO
NOT pinch or damage the Sip-N-Puff tubing.
– Saliva trap MUST be installed to reduce risk of
water or saliva entering the Sip-N-Puff interface
module.
– Flush the mouthpiece and the breath tube at
least twice a week with warm running water.
Disinfect with oral rinse after cleaning.
– The mouthpiece MUST be completely dry
before installation.
– If Sip-N-Puff does not function properly, inspect
system for blockages, clogged saliva trap or
air leaks. As necessary, replace mouthpiece,
breath tube and saliva trap.
For further maintenance and cleaning instructions,
see 6 Maintenance, page 117 .
106
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, see 7.2 OON ("Out Of Neutral"), page121 .
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 Head Array are
pre-set in latched driving mode. For more information, see
5.9 Latched driving mode, page 50.
