Infrared sensor card 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
Use the following procedure on most occasions.
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
A 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.
