Troubleshooting
If the replacement LED does not illuminate when the switch is in the On position, check the following
items:
 Is the power supply in use correct? The light sources require a 12 V power supply with a 2.1mm
centerpositive jack.
 Is the power supply plugged into an outlet that is enabled and standard for the power supply you
are using?
 Is the LED in the correct orientation in respect to the socket (Anode and Cathode)?
If these items are correct and the light source is not emitting light at the proper wavelength (or at all),
please contact Ocean Optics Technical Support.
