Tip: If you use the ear hook, slide the attachment up or down until the headset fits comfortably to your ear.
Remember that two different ear hooks are included. One is very flexible and can be moulded to any angle for an
optimal fit.
3. Audio Signal Tones
The headset generates several types of soft signal tones to let you know when you have an incoming call,
muted call, call on hold, low battery, or another type of event. It also responds each time you use the multifunction button.
4. Headset Visual Indicator
A multicolor LED lets others see when you are on the phone, and it also gives feedback for certain types of events, such as low
battery, incoming call, etc.
