compartment.
The hearing instrument will start up when the battery door is closed. It will take a few
seconds until sound is produced. A jingle is played while the start up process is running.
You may insert the hearing instrument immediately upon closing the battery door.
If the hearing instrument is held in the hand while activated, it may produce a whistling
sound. This will stop when properly tted in the ear.
