Ensure the lock is in the unlocked position
before attempting to open the battery door.
Excessive force used to open the battery
door when in the locked position can result in
permanent damage and reduce the safety of
the instrument. Please contact your hearing
care professional if you suspect excessive force
has been used or the door is damaged.
Do not force the battery door beyond its
fully opened position. Make sure to insert the
battery correctly. The use of excessive force
can deform the battery door, which will reduce
its tamper-resistant effectiveness and locking
ability.
