Toshiba RAV-SM801BT-E Error Mode Detected by LED on Outdoor P.C. Board, CDB side, Ipdu side

10-3. Error Mode Detected by LED on Outdoor P.C. Board

RAV-SM800AT-E

<SW800: LED display in bit 1, bit 2, bit 3, bit 4 OFF>

•When multiple errors are detected, the latest error is displayed.

•While LED displays 〇 (go on), there is the main cause of error in control at CDB side and it stops abnormally.
