before you put on the Adhesive to enhance the stick-
ing properties of the Provox
about 30 seconds and then apply the Adhesive base
plate. [picture P2]
Provox Silicone Glue (REF 7720), can be used to
®
prepare the skin before applying the Adhesive base
plate, thus providing a better seal.
STEP.2.–.PREPARATION.OF.THE.DEVICE
Place a Provox
surface, with the plastic grid down and the open foam
surface on top. Place the valve housing on top of the
HME Cassette and push it down until it clicks, and the
Cassette is tightly fixed to the housing. Check the proper
fit manually. [picture P3]
Hold the device with the HME Cassette facing away
from you. When looking at the top of the speech valve
unit, twist the housing counter-clockwise until it stops.
The valve is now in the "breathing position" (OFF).

STEP.3.–.INSERTION.AND.ADHESIVE.SEAL
Insert the Provox
Adhesive base plate (REF 7251-56, 7265) and breathe
normally. [picture P5]
Inspect the Adhesive seal with means of a mirror.
There should be no leakage. This can be achieved by
massaging the Adhesive base plate onto the skin. [pic-
ture P6] If there is still leakage, a new Adhesive base
plate should be used and carefully applied to the skin.
Skin-Prep and Provox
™
enhance the seal of the Adhesive base plate. (The sili-
cone glue is not included in the package.)
ON (= automatic function; i.e., the valve lets you
breathe and talk)
To switch the valve ON, twist the housing of the
device in the opposite direction as in step 2, until you
feel it stop, [picture P7]. You should now try to speak
some words, beginning with low volume and pressure.
In case you feel increased breathing resistance after
coughing, you may have to take out the whole device
for wiping the mucous away, or to replace the HME
cassette with a new one.
OFF (= only breathing possible; for use e.g. during
harder physical activities)
For heavier breathing turn the valve into the OFF
position (like in step 2, you can do that while the valve
is attached to the stoma). [picture P8]. This should avoid
unwanted valve closure and also minimize the breathing
