WHAT IS BLUETOOTH?
Bluetooth wireless technology provides a way for devices to communicate with each  other using short-range radio frequency instead of wires. Any two  communicate as long as they both have  they have been paired--a quick “handshake” process that connects the two devices. 
Bluetooth range is up to 33 feet (10 metres). Obstructions, such as walls or other  electronic devices, can cause interference or shorten the effective range. For optimal  performance, place your headset and phone on the same side of your body.

Tips
If you’re wearing the headset, you hear ascending tones when the power turns on and 
descending tones when the power turns off.
When you receive a call, your phone may ring before your headset rings. Wait until you  hear the ring in your headset before you press the call control button to answer the  call.
For best performance, position your phone on the same side of your body as your  headset.  
To quickly re-connect to your recently used device that is within range, briefly press  the call control button.
To cancel an outgoing call, briefly press the call control button.
USING YOUR HEADSET
Answering/Ending/ Making Calls with PerSonoCall on an Internet calling application
To make a call, simply dial the number via your internet calling application.
To answer or end a call, press the call control button.
When using PerSonoCall, the radio link between the headset and the USB  adapter will only be active during a call. This is the default setting intended to preserve the  battery life of the headset. However, you may wish to have the radio link active when not  on a call so you can listen to other audio sources, such as streaming audio on your PC. 
NOTE: Locking the radio link on for extended periods of time will significantly reduce the standby 
and talk time of the headset.
For internet calling applications Not Compatible with PerSonoCall
Check the PerSonoCall compatibility list at www.plantronics.com/personocall for the most  current information on internet calling application compatibility.
If your internet calling application is not currently supported by PerSonoCall, remote  detection and answer/end via the headset does not function. Pressing the call control  button on the headset will only open and close the radio link providing audio; you must  answer the call from the internet calling application.

RANGE
To maintain a connection, keep your headset within 33 feet (10 metres) of the Bluetooth  device. If there are obstacles between your headset and the device you may experience  interference. For optimal performance, place your headset and phone on the same side of  your body.
As you move out of range, audio quality degrades. When you are far enough away to lose the  connection, you hear a high tone in the headset. The headset attempts to reconnect after 30  seconds. If you move back in range later, you can manually reconnect by pressing the call  control button.
NOTE: Audio quality is also dependent upon the device with which the headset is paired.

A plug and jack used to connect this equipment to the premises wiring and telephone network must comply  with the applicable FCC Part 68 rules and requirements adopted by ACTA. A compliant telephone cord and  modular plug is provided with this product. It is designed to be connected to a compatible jack that is also  compliant. See installation instructions for details.
The REN is useful to determine the quantity of devices you may connect to your telephone line. Excessive  RENs on a telephone line may result in the devices not ringing in  response to an incoming call. In most, but  not all areas, the sum of the RENs should not exceed five (5.0). To be certain of the number of devices you  may connect to your line, as determined by the REN, contact your local telephone company. For product  approved after July 23, 2001, the REN for this product is part of the product identifier that has the format US: AAAEQ##TXXXX. The digits represented by ### are the REN without the decimal point. (For example, 03  represents a REN of 0.3.) For earlier products, the REN is  separately shown on the label.
If this telephone equipment causes harm to the telephone network, the telephone company will notify you in  advance that temporary discontinuance of service may be required. But if advance notice isn’t practical, the  telephone company will notify the customer as soon  as possible. Also, you will be advised of your right to file  a complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its  facilities, equipment, operations, or procedures that could  affect the proper functioning of your equipment. If they do, you will be notified in advance in order for you to  make necessary modifications to maintain uninterrupted service.
If trouble is experienced with this unit, for repair or warranty information, please contact customer service at  (800) 544-4660. If the equipment is causing harm to the network, the telephone company may request that you  disconnect the equipment until the problem is resolved.
DO NOT DISASSEMBLE THIS EQUIPMENT: It does not contain any user serviceable components. We recommend the installation of an AC surge arrester in the AC outlet to which  this equipment is connected.
