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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.

Individual manufacturer's instruction should be followed for use of this disinfecting
agent to provide an appropriated level of cleanliness
Notice - Never insert or in any way use the insert headset without a new clean non
defect test tip.
Notice - Do not site the PKA87 next to a radiator or any other heat source.
Notice - In operation the instrument should not be subject to temperatures below
15C° or above 35C°.
Notice - 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.
