For Model 98:
To lock the battery door:
1. Insert the tool straight into the battery door
lock.
2. Slide lock to the left. An indication mark
shows that the battery door is in the locked
position (you will be able to see a white dot).
To unlock the battery door simply repeat the same procedure but pushing the slider to the right
instead. You can now change the battery as described in “How to change the battery”.
Low battery warning
When the batteries are low on power, your hearing aids reduce the volume, and play a melody
every 15 minutes until they are completely drained and turn off.
