NTENDED USE
Bell & Harp audiometers are designed for use by audiology and hearing
healthcare specialists or trained technicians in conducting diagnostic hearing
evaluations and assisting in the diagnosis of possible otologic disorders.
Audiometric tests must be conducted in particularly quiet environment, and
preferably in a soundproof booth. If these conditions cannot be provided, the
patient should be given sound-isolating headphones to wear, so that ambient
and background noise can be blocked out as far as possible.
P
RECAUTIONS
Users are entirely responsible for any malfunction caused by
improper use, or by maintenance or repair operations
performed by any party other than Inventis srl or an authorised
Service Centre.
Installation
If the audiometer is connected to other devices, obtaining an
electromedical system, this system must be complying with IEC
standard 60601-1.
Avoid installing and using Bell & Harp audiometer close to any
sources of strong electromagnetic field: these could interfere
with the operation of the device.
Calibration
The calibration is valid only for the transducers supplied with the
device. If a transducer is replaced, the audiometer must be
recalibrated.

presented it to the patient.
