Low Battery Warning
When the battery voltage nears the end of life, the MDHearingAid AIR
will provide a low battery warning signal. The initial warning will be three
sets of double beeps every 10 minutes. At this point the hearing aid is still
functioning, but it is recommended that batteries be replaced as soon as
possible.
When the battery is too weak for further operation, the MDHearingAid AIR
will issues six sets of double beeps, and then shut down all audio output of
the hearing aid. At this point the unit will not be usable until a fresh battery is
installed.
