However, the instrument should
NOT
be left switched on with the dust cover
in place, as this may cause severe overheating and damage to the
instrument. Do not expose the instrument to direct sunlight and keep it well-
ventilated at all times to prevent overheating.
CAUTION!
The earphones are in constant contact with your patients so care should be
taken to ensure that they are kept clean. Just wipe them regularly with a moist
cloth. Likewise, the eartip of the masking insert phone should be wiped
regularly, and replaced at frequent intervals. There are no special
requirements for disposal of the rubber eartip. The bone vibrator (conductor)
should also be wiped clean periodically.
If you use the E-A-RTONE 3A insert earphones, note that the standard yellow
foam insert tips are disposable, and therefore should not be cleaned and
reused. There are no special requirements for disposal of the insert tips.
