When the battery is running out, the instrument
will beep at regular intervals. You should be
prepared to replace the battery. The time until the
instruments stop working depends on the battery
type and manufacturer. Mercury-free batteries
generally cause earlier warning beeps.
Your hearing instrument uses a size 312 battery.
To Change the Battery:
· Gently swing the battery
door fully open, but do not
force it.
· Remove the used battery.
· Remove the sticker from
the new battery.
· Place the battery into the
door with the at, smooth
side facing up (+
sign).
· Close the battery door
securely.
