Low battery warning
When the battery voltage nears the end of
life, the device will detect this condition and
provide a low battery warning signal. The fi rst
warnings begin when the average voltage
falls below 1.05V. At this time, the device emits
three sets of double beeps every 10 minutes.
When the average voltage falls lower than
0.95V, the device issues six sets of double
beeps, and then shuts down the audio output
of the hearing aid. Low battery warning can be
disabled by programming.
