5.2 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.
