Replacing The Battery - oticon sensei BTE312 Instructions For Use Manual

Replacing the battery

The BTE13 90 uses a battery size 13. The BTE312 75 uses a
battery size 312.
A worn out battery should be removed immediately and
disposed of according to local regulations.
When the battery power is low, the visual indicator (LED)
will rapidly blink and the user will hear 2 beeps (if enabled).
This pre-warning starts when the battery has only a few hours
of operation left. The 2 beeps will be repeated in moderate
intervals to indicate it is time to change the battery.
If the battery runs out the hearing aid turns off. When that
happens, 4 beeps are played and the visual indicator (LED) will
turn off (if enabled) to indicate that the hearing aid is no longer
operating.
Replace the battery.
