4. Using your Phonak CROS system
Open and close the battery compartment gently
and carefully.
Check if you feel resistance when closing the
battery compartment. Check to make sure
the battery is correctly inserted and in the correct
direction. If the battery is inserted the wrong
way, the Phonak CROS transmitter will not work
and the battery compartment can be damaged.
The Phonak CROS transmitter is now switched on. It
can take up to 15 seconds before it starts.
(When you wear the hearing aid, you will hear an
acoustic signal).
