ERRS 
Use the command ERRS to display all current device errors, 
unacknowledged errors, and error log contents. 
An error is active if the cause for the error is still present when you 
execute the ERRS command. If the cause disappears, the error 
message changes to the unacknowledged state. An unacknowledged 
error is an error message that has not yet been displayed to the user. 
Unacknowledged errors are automatically cleared when they are 
displayed with 
ERRS command or with the optional display and 
keypad.
