The batteries last from a few days up to several weeks
according to the way they are used. You can recognise when
a change of batteries becomes necessary, because your
hearing instruments become noticeably quieter towards the
end of the battery's life. Then it is time for new batteries.
Two warning tones sound once per minute indicating
that you must insert a new battery.
Your hearing instrument specialist can switch off the warning
tones if required.
Safety notes for batteries
WARNING

Batteries must not be swallowed.
Remove the batteries when the instrument is not in
use over a prolonged period. Replace leaking batteries
without delay.
Do not throw away your dead batteries!
Return them to your hearing instrument specialist for
proper, environmentally conscious disposal.
