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.
Put on the hearing instruments 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.
