IMPORTANT NOTICE
Do not use the mute function as a switch off as the hearing aid still draws power from
the battery in this mode.
Tamper-resistant battery door (Optional)
A special battery door may be installed with your hearing instrument which protects
against unintended operation of the battery door and battery.
This is strongly recommended for infants, small
children and people with learning difficulties.
The battery door is designed only to be opened by
using a tool. Use the MultiTool to unlock the door by
inserting it into the slit in the bottom of the hearing
instrument and pushing on the door to open.
Important: Do not force the battery door beyond its
fully opened position. Insert the battery correctly.
Excessive force can damage the battery door and thereby
reduce its locking ability.
