Interacoustics AC40 Gebrauchsanweisung Seite 1223

AC40 Instructions for Use - US
When the instrument is connected to a PC and other items of equipment of a medical electrical system
assure that the total leakage current cannot exceed the safety limits and that separations have the dielectric
strength, creepage clearances and air clearances required fulfilling the requirements of IEC/ES 60601-1.
When the instrument is connected to a PC and other similar items be aware of not touching the PC and
patient simultaneously
To avoid the risk of electric shock, this equipment must only be connected to supply mains with protective
earth.Do not use any additional multiple socket-outlet or extension cord.
This instrument contains a coin-type lithium battery. The cell can only be changed by service personnel.
Batteries may explode or cause burns, if disassembled, crushed or exposed to fire or high temperatures. Do
not short-circuit.
No modification of this equipment is allowed without Interacoustics authorization.
Interacoustics will make available on request circuit diagrams, component part lists, descriptions, calibration
instructions, or other information that will assist service personnel to repair those parts of this audiometer that
are designated by the Interacoustics as repairable by service personnel
Never insert or in any way use the insert headset without a new clean non defect test tip. Always make sure
that foam or ear-tip is mounted correctly. Ear tips and foam are single use.
The instrument is not intended to be used in environments exposed to fluid spills.
It is recommended that the disposable foam ear tips supplied with the optional insert transducers are
replaced after testing each patient. Disposable plugs also ensure 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.
To ensure correct cooling of the device, please ensure free air flow on all sides of the instrument. Make sure
that cooling ribbons are not covered. It is recommended to place the instrument on a hard surface.
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
concideration in the appendix.
