Sony DR-BTN200 - Manual (Page 32)

HFP (Hands-free Profile)*: Talking on the phone/Operating the phone by
hands-free.
* When you use a BLUETOOTH mobile phone supported by both HFP (Hands-free
Profile) and HSP (Headset Profile), set it to HFP.
Notes
To use the BLUETOOTH function, the BLUETOOTH device to be connected
requires the same profile as that of the headset. Even if the device has the same
profile, functions may vary depending on the specifications.
Due to the characteristic of BLUETOOTH wireless technology, the sound played
on the headset is slightly delayed from the sound played on the BLUETOOTH
device during talking on the telephone or listening to the music.
Do not use the BLUETOOTH function on an airplane. The radio waves may
cause malfunction of the airplane and result in hazardous accidents.
