630 Chair Error Codes Troubleshooting
When S3 button is pressed, then released, you will hear a “beep” to indicate displaying of errors. Most recent displaying first. When switching errors, the board will again emit a “beep”. The displays will show “FFFF” if there are not ten errors to display. After all ten errors have been displayed you will hear three ”beeps”.
Green Display
The green display indicates the function or system where the problem occurs. Example: 02 = Base
Red Display
The red display indicates what problem or symptom was detected. Example: 09 = Switch Error
Use care when identifying Error Codes as some digits are similar.

1.Unplug chair power cord.
2.When the digital display darkens, move S2 switches three and four to ON (up).
3.Plug in chair power cord.
4.When the digital display darkens, press and release S3 button.
5. When all errors have been displayed, pressing and releasing S3 button again will repeat errors.
6.When recall is complete, unplug chair power cord.
7.Move S2 switches three and four to OFF (down).
8.When the digital display darkens, plug in chair power cord.
