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 will vary
depending on current conditions (obstacles, battery power, interference, etc.).
•
The headset can be connected only to devices that support the Bluetooth headset or hands-free
profile. This product is not compatible with standard cordless phones.
Battery life
With average use, the battery should provide about 9 hours of talk time and 8 days of standby time. A
battery that is new or left unused for long periods of time can have reduced capacity the first few times
it is used. For maximum battery life, keep your 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 changed 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 connect the charger or 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
•
Any equipment that uses microwaves, especially
microwave ovens
•
Wireless LAN equipment or WiFi connections
If you have problems with static during calls, look around 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, check around for things that might interfere with your phone.
•
Other Bluetooth devices or computer
•
Certain cordless telephones
•
Certain medical equipment and appliances
