Step 3: Adjust Volume
The AIR uses a volume dial with numbers from
1 (minimum) to 4 (maximum).
• To increase volume, rotate volume dial up.
• To decrease volume, rotate volume dial down.
Caution! To avoid a sudden blast of sound, please
raise the volume SLOWLY.
Please note: Whistling may be heard if the AIR is
turned on but not positioned securely in your ear.
Once the ComfortTIP is properly inserted, whistling
will stop.
