Replacement battery
This hearing aid requires zinc-air batteries. Identify the
correct battery size (312 or 10) by:
• Checking “Your hearing aid details” on page 5.
• Checking the marking on the inner side of the
battery door.
• Checking the following table.
If it is difficult to close the battery door: Check that
the battery is inserted correctly and the “+” symbol is
facing upwards. If the battery is not inserted
correctly, the hearing aid will not work and the
battery door can be damaged.
Please ensure you use the correct type of battery in
your hearing aids (zinc-air). Please also read chapter
21.2 for further information on product safety.
