1.6 PRECAUTIONS
• Always test the function of the Provox XtraHME Cassette prior to use. The
top lid should immediately return to its open position after releasing the
fi
nger.
• Do not disassemble the Provox XtraHME Cassette since this will interfere
with its proper function.
• Do not reuse the Provox XtraHME Cassette or attempt to rinse it with water
or any other substance. This will substantially reduce the function of the
HME. Additionally the risk of potential infections may increase due to
bacterial colonization of the foam.
• Do not use the Provox XtraHME Cassette longer than 24 hours. The risk
of potential infections may increase with the time of use due to bacterial
colonization of the foam.

To speak, press the top lid of the Provox XtraHME Cassette down with

Note:
Always release the lid completely at inhalation to avoid increased
