Appendix E. Cleaning Procedure
Cleaning Procedures
To assess the projection of the emitted light beam you can use an
infrared sensor card. Hold the card approximately 5 cm from the
output of the connector. The invisible emitted light is project onto
the card and becomes visible as a small circular spot.
Preferred Procedure
1 Clean the connector by rubbing a new, dry cotton-swab over the
surface using a small circular movement.
2 Blow away any remaining lint with compressed air.
Procedure for Stubborn Dirt
Use this procedure particularly when there is greasy dirt on the
connector:
1 Moisten a new cotton-swab with isopropyl alcohol.
2 Clean the connector by rubbing the cotton-swab over the surface
using a small circular movement.
3 Take a new, dry soft-tissue and remove the alcohol, dissolved
sediment and dust, by rubbing gently over the surface using a
small circular movement.
4 Blow away any remaining lint with compressed air.
An Alternative Procedure
The better, more gentle, but more expensive cleaning procedure is
to use an ultrasonic bath with isopropyl alcohol.
1 Hold the tip of the connector in the bath for at least three
minutes.
2 Take a new, dry soft-tissue and remove the alcohol, dissolved
sediment and dust, by rubbing gently over the surface using a
small circular movement.
3 Blow away any remaining lint with compressed air.
