Introduction
Intended Use
The PKA87 screening audiometer is designed to be a device for screening for
hearing loss. Output and specificity of this type of device are based on the test
characteristics defined by the user, and may vary depending on environmental and
operating conditions. The screening for hearing loss using this kind of audiometer
depends on the interacti
on with the patient. “normal hearing” result should not allow
for ignoring other contra indications. A full audiologic evaluation should be
administered if concerns about hearing sensitivity persist
The PKA87 audiometer is intended to be used by an audiologist, hearing healthcare
professionals, or trained technicians in a quiet environment. It is recommended that
the instrument be operated within an ambient temperature range of 15-35 degree
Celsius (59-95 degrees Fahrenheit)
This manual describes the Diagnostic software used for PC Audiometry.
The Software allows users to working and display, store and print audiometric data.
Precautions
Notice -
Be sure to use only stimulation intensities, which will be acceptable for the
patient.
Notice -
The transducers (headphones, bone conductor, etc.) supplied with the
instrument are calibrated to this instrument - exchange of transducers require a
recalibration.
Notice -
It is recommended that parts which are in direct contact with the patient
(e.g. earphone cushions) are subjected to standard disinfecting procedure between
patients. This includes physically cleaning and use of a recognised disinfectant.
