13.2 Maintenance
The MI 24 is designed to require minimal maintenance and should provide you with
years of trouble-free use. The following suggestions may assist you in avoiding
and/or solving problems.
Calibration:
The optimum length of time between recalibrations for impedance meters or
audiometers varies, depending upon the treatment given the instrument and the
headphones/probe. It is recommended that the instrument have a laboratory
calibration at least once every year. Since rough handling, such as dropping the
probe, can easily cause calibration errors it is advisable to establish a biological
calibration check as soon as you receive the instrument.
Should you feel at a later date that the impedance or audiometer’s calibration may
be in error, perform a biological check on a known ear. If all retests show major
changes, calibration is probably in error.
All repair and recalibration should be done at an authorized Maico Special
Instruments Distributor service center. This assures the use of quality materials by
trained and experienced technicians using the proper, accurate equipment.
Maico Special Instruments Distributors are located in major cities throughout the
world. To minimize costs and time delays, contact the Distributor that you
purchased the instrument from. If you don’t know who that is, or need to find the
Distributor closest to you, contact the factory at:
