When the battery is low, your hearing instrument
will beep at regular intervals. You should be prepared
to replace the battery. The time until the hearing
instruments stop working depends on the battery type
and manufacturer. Mercury-free batteries generally
cause earlier warning beeps.
Change Batteries Regularly
When your battery needs to be changed you will hear
three beeps: a low tone, followed by a high tone and
another low tone. The exact battery life you experience
may vary, but you should expect approximately 238
hours of total hearing instrument use per battery.
Important! Never force the battery drawer
open or closed.
