Tamper proof battery compartment
To protect children from the dangers of playing with
batteries, a special locking system may be mounted on
the instruments. This locking system can also be used
for identifying left and right instruments (see page 15).
To lock the battery compartment after it is closed:
Use a Phonak screwdriver and turn the screw to its
middle position (slot vertical).
To unlock the battery cover: Turn the screw until
it stops.
