5.1 Getting Started with the MA 1
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 Switching the Device On and Off
Switch on the device by pressing the black right/left button to turn on the MA 1.
An automatic power shutoff occurs after 90 s of inactivity to conserve battery life.
