5.16 Bluetooth
Bluetooth is a proprietary, open wireless technology standard for exchanging data
over short distances from fixed and mobile devices, creating personal area networks
with high levels of security. On DW-820, users could use Bluetooth to transfer files,
share contact information with other Bluetooth portable devices by installing
Bluetooth Application, or use Bluetooth headset for making calls.
To connect to a Bluetooth device, turn on DW-820’s Bluetooth radio first. The first
time when using a new Bluetooth device with the DW-820, “pair” the device with
DW-820 so that both devices know how to connect securely to each other. After that,
users could simply connect to a pared device. Turn off Bluetooth if it’s not used.
Bluetooth related settings are under DW-820’s Settings application → Wireless &
