Event and state notifications¶
You may receive notifications from NAO system or from an application.
In that case, a small sound is played and the status LEDs remain still white but blink once in a while with a colour indicating the severity of the notification.
| Status LEDs is ... | Severity | |
|---|---|---|
Steady White light, cut by a brief blinking in ... |
 Green |
NAO gives you some feed-back by an Info notification about an ongoing action. |
 Yellow |
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 |
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.
