Explanation
• Is the specified AC adaptor (PSA series; sold separately) properly connected?
• Never use any AC adaptor other than one specified for use with the BR-80.
Is sufficient power being supplied to your computer or USB hub?
The connection cannot be established if insufficient power is being supplied to
the BR-80. Make sure that none of the following cases apply.
• If you're using a notebook computer that's running on its battery, operation
may be unstable in the case of some computers. In this case, connect an AC
adaptor to your computer.
• The power management settings of your computer may be limiting the power
that is supplied to USB. Check the settings on your computer.
• In some cases, the BR-80 cannot be used with bus-powered hubs (USB hubs
that do not contain a power supply). Please use a self-powered hub (a hub
that contains a power supply).
