activating the hearing instrument for the first time
A hearing instrument is a miniature electronic device that runs on special batteries.
To activate the hearing instrument, you must insert a fresh battery in the battery
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 put on 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 fitted on the ear.
