General Information
•You cannot use the headset while it is recharging.
•Bluetooth wireless devices have a maximum range of 30 feet (10 m); the actual range varies depending on current conditions (obstacles, battery power, interference, etc.).
•The headset can be connected only to devices that support the Bluetooth headset or
Battery life
•With average use, the battery should provide about 6 hours of talk time and 7 days of standby time. If a battery is new or left unused for a long time, it can have reduced capacity the first few times you use it. For maximum battery life, keep the battery charged.
•When the battery only has enough charge for about 15 minutes of talk time, the headset triggers a low battery alert: you’ll hear a periodic beep, and the LED changes from blue to red.
•When the battery no longer has enough charge to operate the headset, the headset will power off; you won’t be able to turn it back on until you charge the battery.
Noise or Static on the Headset
The most common cause of noise or static on any wireless device is interference. Bluetooth devices operate in the ISM band (2.402 GHz ~ 2.480 GHz); any equipment operating in this frequency range might interfere with the headset. Some common sources of interference in this range are
•Equipment that uses microwaves, especially microwave ovens
•Wireless LAN equipment or WiFi connections
•Other Bluetooth devices or computers
•Certain cordless telephones
•Certain medical equipment and appliances
If you have problems with static during calls, look for one of these interference sources. Try moving away from the suspected source.
If the noise continues, there may be interference on your phone itself, and any noise in the phone’s connection will come through on the headset, too. Transfer the call to your phone and see if the audio quality improves. If it doesn’t, look around for things that can interfere with your phone.
