User's Manual

Bluetooth systems create a personal-area network (PAN), or piconet, that may fill a room or may

encompass no more distance than that between the cell phone on a belt-clip and the headset on your

head.

When Bluetooth-capable devices come within range of one another, an electronic conversation takes

lace to determine whether they have data to share or whether one needs to control the other. The user

doesn't have to press a button or give a command -- the electronic conversation happens automatically.

Once the conversation has occurred, the devices -- whether they're part of a computer system or a stereo

-- form a network.

Once a piconet is established, the members randomly hop frequencies in unison so they stay in touch

with one another and avoid other piconets that may be operating in the same room.

One of the ways Bluetooth devices avoid interfering with other systems is by sending out very weak

signals of 1 milliwatt. By comparison, the most powerful cell phones can transmit a signal of 3 watts.

The low power limits the range of a Bluetooth device to about 10 meters, cutting the chances of

interference between your computer system and your portable telephone or television. Even with the low

ower, the walls in your house won't stop a Bluetooth signal, making the standard useful for controlling

several devices in different rooms.
