Low Battery Warning
The hearing instrument has a soft low-battery-warning signal
(beep-beep) that you will hear when the battery voltage/power
gets too low. The signal indicates you should replace the bat-
tery. We recommend that you always carry a spare battery with
you. The low-battery-warning signal will be repeated every 5-10
minutes until the battery runs out of power. The instrument will
then automatically switch off.
Changing the Battery
Open the battery compartment completely, using your nger-
nail to pull back on the small ridge located at the top of the
door. After removing the old battery, insert the new one with
the“+” (at) side facing the “+” on the battery door. Make sure
the battery has been placed correctly into the slot. The battery
door should close very easily. Never use force to close the door
as this may damage your hearing instrument.
ES70 & ES80
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 the
instrument will help prevent corrosion of the battery contacts
and prolong battery life.
