IMPORTANT SAFETY INSTRUCTIONS
The CA850 instrument must be used only by practitioners qualified to perform
audiometric tests. It is intended for use as a screening tool.
2.1
PRECAUTIONS
READ THIS OPERATING MANUAL BEFORE ATTEMPTING TO USE THE INSTRUMENT.
To comply with the standards IEC 60601-1 for safety and IEC 60601-1-2 for EMC the audiometer is designed
to be used only with the medically-approved mains adapter supplied, which is specified as part of the
equipment.
Do not use any other type of mains adapter with this instrument. Refer to Section 17 for the
stock number of the adapter.
The audiometer is for indoor use only and should be used only as described in this manual.
The transducers supplied with the audiometer are specifically calibrated with it; if these transducers are
changed calibration will be required.
Do not immerse the unit in any fluids. See Section 16 of this manual for the proper cleaning procedure for the
instrument and its accessories.
Do not use the instrument in an oxygen-rich environment or in the presence of a flammable anaesthetic mixture
or other flammable agents.
Do not drop or otherwise impact this instrument. If the instrument is dropped or damaged, return it to the
manufacturer for repair and/or calibration. Do not use the instrument if any damage is suspected.
The instrument must be stored and used within the specified temperature, pressure and humidity ranges (see
Section 13).
Do not attempt to open, modify or service the instrument. Return the instrument to the manufacturer or
distributor for all repair and servicing requirements. Opening the instrument will void the warranty.
2.2
ELECTROMAGNETIC COMPATIBILITY (EMC) CONSIDERATIONS
Medical electrical equipment needs special precautions regarding EMC and needs to be installed and put into
service according to the EMC information in Appendix 2. This provides guidance on the electromagnetic
environment in which to operate the instrument.
Portable and mobile radio-frequency (RF) communications equipment can affect medical electrical equipment.
The instrument should not be used adjacent to or stacked with other equipment; if this is unavoidable the
instrument should be observed to verify normal operation.
2.3
MAINS SUPPLY OPERATION
The audiometer is designed for continuous operation and is powered by a mains adapter which is supplied,
and specified as part of the equipment. If a replacement is required, please contact Amplivox or your Amplivox
distributor.
All other connections must be made
before
connecting the output lead from the adapter into the POWER
input socket on the back of the audiometer. Switch on the mains supply - the indicator on the adapter and the
POWER indicator on the audiometer will both illuminate green, showing that the instrument is ready for use.
The output from mains adapter is fitted with electronic circuit protection. In case of overload the adapter will
shut down and the indicator will be extinguished. When the fault is cleared the adapter will operate as normal.
The input to the mains adapter is protected with a non-replaceable fuse. If this fails the adapter will not operate.
