Playing Music from the Mobile Phone through the HKT 450 First, make sure your mobile phone supports Bluetooth Advanced Audio Distribution Protocol (A2DP) and Audio Video Control Protocol (AVRCP) functions (on some phones the A2DP function may appear as AV function).

Due to variations of mobile phones, procedures to play music through the HKT 450 are not always the same. When the Speakerphone is paired with a mobile phone, depending on the software in the mobile phone, there are a number of ways to initiate music playing. For some phones, music play through the HKT 450 is automatic; when the music player on the mobile phone is started music will be streamed through the HKT 450 automati-
cally. Some mobile phones will require that the Mode Button on the device be pushed to initiate the A2DP function. Other mobile phone models will require the user to select the device used to hear the music when the music player is started.
(Always refer to the User Guide of your mobile phone for details on playing music through A2DP) Note:
