Bluetooth accessory tips
• Non-DRM formats such as MP3 provide the best audio
with Bluetooth stereo headsets. When listening to
DRM protected content using Bluetooth stereo head-
sets it is recommended to wait until the DRM content
is finished playing before accessing other functions or
applications of the device such as email, Gallery, visu-
alizations.
• To maintain headset connection with the device it is
recommended to charge the headset periodically and
to stay within range.
• Sometimes there may be mono audio vs stereo audio
after reconnection, unpair and reset headset, then
reconnect via the Options menu.
