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

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. Your GoBook MR-1 is a Class II Bluetooth device with a
range of about ten meters. Even with the low power, the walls in your house won't stop a Bluetooth signal. This

degrade the signal and reduce its range.
