Changing the Battery
When the battery voltage/power decreases to a certain level,
the instrument will stop amplifying and emit a soft beeping
signal. This signal will continue for about one minute and
then the instrument will be automatically switched off.
Therefore, it is recommended that you keep a spare battery
on hand.
Open the battery compartment by turning the instrument
off. After removing the old battery, insert the new one with
the "+" (flat) side facing the "+" on the battery door. It
should fit in like a puzzle piece. The battery door should
close very easily. Never use force to close the door as this may
damage your hearing instrument.
Always use a size 13 Zinc-Air battery. Please note that if the
battery is weak, the hearing instrument performance will be
reduced. Removing the battery when you are not wearing it
will help prevent corrosion of the battery contacts.
