Disposal
·
There are no special requirements for disposal of the rubber eartips.
Probe Tip
·
The probe tip must be frequently checked for cerumen (ear wax)—even
a partial blockage will affect the accuracy of your measure- ments. Ce-
rumen may be removed by means of the supplied metal pin (cleaning
wire)—see below.
Do NOT attempt to clean any of the tubes in the probe tip without
first removing the attached plastic tubes as described below.
Procedure For
Cleaning Probe Tip 1. First detach the probe tip from the 3 plastic tubes.
2.
Use the supplied metal pin (cleaning wire) to push out cerumen from
each metal tube in the probe tip.
3.
Re-attach the 3 plastic tubes to the probe tip.
