USING THE OTOWAVE
4.1.
INSTALLING & REPLACING BATTERIES
The Otowave 102 may be
powered from Alkaline ‘AA’ batteries or rechargeable Nickel-Metal Hydride (NiMH)
batteries . Four batteries are required. Do not mix battery types or old and new batteries.
If the Otowave is to be used infrequently the use of alkaline cells is recommended. NiMH batteries have a high
self-discharge rate and are likely to need recharging if left unused for several weeks.
Remove batteries from the instrument if it is not going to be used for more than a.
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 0).
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.
