Battery Information

Low Battery Warnings:

When the battery voltage nears the end of its life, the MDHearingAid
will provide Low Battery Warning signals.
The Initial Warning will be three sets of double beeps. It is recommended
that the battery be replaced as soon as possible.
When the battery is too weak for further operation, the Final Warning will be
six sets of double beeps (resembling a motor boat sound). The hearing aid
will then shut down all audio output until a fresh battery is installed. Follow
the Battery Replacement Procedure on the next page.
Please note: Due to variations among battery manufacturers certain
batteries, when new, will give a false Low Battery Warning. For best
results, use Battery Replacement Procedure on the next page.
