Page 8 OM001-16 Otowave 102 Operating Manual
Remove batteries from the instrument if it is not going to be used for more
than a month (refer to Section 14 for the internal memory hold-up time).
The type of cell fitted must be set in the CONFIGURATION menu. By
default this is ALKALINE. Change the setting in the CONFIGURATION
menu (scroll to BATTERY TYPE as described in Section 12.2).
To fit the cells remove the battery compartment cover on the base of the
tympanometer. Fit the cells as indicated inside the battery compartment
and replace the battery compartment cover.
Batteries should only be changed outside the patient
environment. The operator should not touch the
battery connectors and the patient simultaneously.
A battery state indicator is shown in the top right corner of the display
(except when showing test results). This shows the battery state as a
progressively emptying battery. The batteries should be replaced when the
symbol “!” appears next to the battery state indicator, or when advised to
do so, for example at switch-on.
Changing the batteries does not affect the configuration, the contents of the
database, the calibration settings or the results of the last test.
Note that local regulations are likely to cover disposal of used batteries.

To set the operating language (English, French or German) use the options
within the CONFIGURATION menu (see Section 12.2).
