5.1 Getting started with the MA 25/MA 25e and the MA 27/MA 27e
5.1.1 Use of Equipment After Transport and Storage
Make sure the device is functioning correctly before use. If the device has been stored
in a colder environment (even for shorter time) allow the device to become
acclimatized. This can take a long time depending on the conditions (like environmental
humidity). You can reduce the condensation by storing the device in its original
packaging. If the device is stored under warmer conditions than the use conditions, no
special precaution are required before use. Always ensure proper operation of the
device by following routine check procedures for audiometric equipment.
5.1.2 Where to Setup
The MA 25/MA 25e and MA 27/MA 27e should be operated in a quiet room, so that
the audiometric examinations are not influenced by outside noises. Ambient sound
pressure levels in an audiometric test room shall not exceed the values specified in the
norm ISO 8253-1:2010 or ANSI S3.1-1999..
Devices, which emit strong electromagnetic fields (e.g. cellphones, microwaves or
radiotherapy devices), can influence the function of the audiometer. Therefore, it is not
recommended to use these devices in close proximity to the audiometer as it may lead
to incorrect test results.
The test room must be at a normal temperature, usually from 15° C/59° F to 35 °C/95° F,
and the device should be switched on approximately 10 minutes before the first
measurement. For further information on use after transport and storage see section 6.1.
Place the device on a stable counter or table. Connect all accessories with the appropriate
sockets as shown in Section 4.2.2. Plug the power cord into a grounded outlet.
