Warning notification occurs when an issue requires your attention and/or action.

NAO is still usable but, it may either run in a degraded mode in which some features may be not available or it may soon become unusable if you don’t solve the problem.

red_chest Red

Error notification occurs when one or all functionality(ies) of NAO become unusable.

Try to solve the problem using the tips. If the problem persists, contact the customer support and provide them with the error ID. For further details, see: Contacting customer support for NAO.

Error and Warning notification messages are prefixed by their severity and their ID when they are said, so that you can give them to the customer support to describe more easily your problem.

Download a printable version: Status LEDs - Cheat sheet.

To ask NAO to read the notification, see: Requesting technical information.
