If sound cuts out while listening to music using the aptX HD codec, you may be able to remedy the problem by switching
to a mode incompatible with the aptX HD codec. The codec (aptX, AAC, SBC) used after switching is different depending
on the connected device.
• Switch to a mode incompatible with the aptX HD codec:
1. When the power is off, slide the power switch toward "ON" while holding the volume control slid toward "–".
2. Display the battery level by sliding the power switch to "ON" or double-tapping the tap controller.
• Confirm that the right indicator lamp lights in blue.
• Switch to the normal mode (the mode compatible with the aptX HD codec):
1. When the power is off, slide the power switch toward "ON" while holding the volume control slid toward "+".
2. Display the battery level by sliding the power switch to "ON" or double-tapping the tap controller.
• Confirm that the right indicator lamp lights in white (normal indicator lamp display).
