Troubleshooting

SBC priority connections (for when sound is delayed significantly)

When the connection codec is AAC, significant sound delays can be alleviated by changing the connection codec to SBC, which comes standard with Bluetooth devices. ^1

Connecting to an SBC priority connection

When the pairing with a Bluetooth device has been completed

1. Turn on the product.

2. While music and videos are paused, slide the jog switch to the minus (-) side (for about 5 seconds).

3. Once the indicator lamp has flashed in white 2 times, the indicator lamp will begin to flash as follows: a quick, white light followed by a 3-second interval, indicating the settings are complete.

4. After the settings are complete, the Bluetooth device that was paired will be automatically connected. *2

Before pairing with a Bluetooth device

1. Turn on the product.
2. While indicator lamp is searching for devices, slide the jog switch to the minus (-) side (for about 5 seconds).

- The indicator lamp will flash in white 2 times.

1. While the indicator lamp continues to flash in this manner (two white flashes followed by a 0.5-second interval), refer to steps 2 and 3 in "Pairing a Bluetooth device" (p. 6) to perform the procedures for pairing.

2. The indicator lamp will flash (a single, quick white flash followed by a 3-second interval) when the settings are complete.

3. After pairing via an SBC priority connection is complete, the only available connection codec will be SBC. Connections using other codecs will not be possible.
4. For details about the indicator lamp's flashing and lit displays, refer to "Indicator lamp display" (p. 15). *3

*1 Depending on the usage environment, changing to an SBC priority connection may not alleviate sound delays.
*2 If the product does not connect automatically, refer to "Pairing a Bluetooth device" (p. 6), and do the procedures for pairing again.
*3 Turning the power off and then back on will result in a return to a normal connection and will enable connections using other codecs. Perform the operations for an SBC priority connection each time it is necessary.
