Procedure 2 Error Code Check
If the power supply microprocessor detects a malfunction, the DC IN LED blinks orange. The blink pattern indicates an error as shown below.
Start | Off for 2 seconds |
Error code (8 bit) |
|
“1” | On for one second |
“0” | On for a half second |
Interval between data bits | Off for a half second |
The error code begins with the least significant digit.
Example: Error code 12h (Error codes are given in hexadecimal format.)

Error code | Meaning |
|
|
10h | AC Adaptor output voltage is more than 16.5 V. |
|
|
