Bluetooth (option)
About Bluetooth
Bluetooth is a short range, wireless technology. Bluetooth systems create a Wireless personal-area
network (WPAN). When Bluetooth-capable devices come within range of one another, an electronic
conversation automatically takes place to determine whether they have data to share or whether one
needs to control the other. Then, the devices hop frequencies in unison so they stay in touch with one
another and avoid interference with other devices.
Bluetooth devices send out weak signals of 1 milliwatt. Class II Bluetooth devices have a range of about
ten meters while Class I devices have a range up to 100 meters. The GoBook XR-1 Bluetooth option is
a Class I device with the greater range. Even with the low power, the walls in your house won't stop a
Bluetooth signal. This makes the standard useful for controlling several devices in different rooms.
However, obstructions such as walls do degrade the signal and reduce its range.
Antennas
The GoBook XR-1 has several embedded antenna options to support wireless communications. They
require no user action.
CAUTION
Use only the supplied or an approved antenna(s). Use of unauthorized antennas,
modifications, or attachments may void your warranty and could impair call quality, damage the radio,
or result in violation of FCC regulations.
