15. Calibration, maintenance and inspection
Clean the puff tube lens on a weekly basis:
1. Moisten a cotton bud with Isopropyl Alcohol.
2. Move the tip of the bud around the lens in a circular motion.
3. After one circle the bud should be discarded to avoid
smearing on the lens.
4. Look at the puff tube lens from the patient’s side, if traces of
tear film can still be seen, repeat above steps until clear.
Note: Care should be taken not to damage the Puff Tube
assembly during cleaning.
Caution
Never use a dry cotton bud or tissue to clean the puff tube lens.
Never use a silicone impregnated cloth or tissue to clean the
puff tube lens.
External cleaning
Keep the unit free of dust.
Keep the chinrest and forehead rest clean.
Regular inspection
Inspect your power supply unit and cable for damage regularly.
Before inspecting, disconnect the power supply from the Pulsair
Desktop and the mains.
If the outer insulation of the cable appears to be damaged
discontinue use immediately. Contact your
local dealer for a replacement.
