Bluetooth Profiles
All the Bluetooth settings you configure are stored in your
phone’s Bluetooth user profile. Different profiles can be used
for specific Bluetooth functions.

Headset Profile – Bluetooth technology connects the
phone to a wireless Bluetooth-enabled headset. When an
incoming call is received, the ringer can be heard through
the headset, instead of the phone. The call can then be
received by pushing a button. Increase or decrease the
volume by using the headset.

phone to a wireless Bluetooth-enabled car kit. Incoming
calls ring to the hands-free headset or device. Calls can be

voice dial, speed dial, and number dial. Increase or
decrease the volume by using the headset.
