It is recommended that the disposable foam ear tips supplied with the optional EarTone5A insert transducers
are replaced after each patient tested. Disposable plugs also insure that sanitary conditions exist for each of
your patients, and that periodic cleaning of a headband or cushion is no longer required.
• The black tubing protruding the foam ear tip is attached to the sound tube nipple of the insert
transducer.
• Roll the foam tip into the smallest possible diameter.
Insert into the ear canal of the patient.
•
Hold the foam tip until expanded and a seal is achieved.
•
• After testing the patient the foam tip including the black tubing is detached from the sound tube
nipple.
• The insert transducer should be examined prior to attaching a new foam tip.
The instrument is not intended to be used in oxygen rich environments or use in conjunction with flammable
agents
NOTICE
To prevent system faults take appropriate precautions to avoid PC viruses and similar.
Use only transducers calibrated with actual instrument. To identify a valid calibration, the serial number for
the instrument will be marked on the transducer.
Although the instrument fulfils the relevant EMC requirements precautions should be taken to avoid
unnecessary exposure to electromagnetic fields, e.g. from mobile phones etc. If the device is used adjacent
to other equipment it must be observed that no mutual disturbance appears.Please also refer to EMC
