Maintenance and Troubleshooting
• Turn off the lamp first, and unplug the power adapter from the power outlet. Wipe any
smears or dusts off the lamp’s outer casing using a soft, lint-free cloth lightly moistened
with a mild detergent solvent. Do not use alcohol or any other chemical solvents like
kerosene, naphtha and so on, as the lamp’s casing may become damaged.
• Do not rinse the lamp or any of its components directly with water.
• If the lamp does not turn on, check to make sure that there are no loose connections
between the power cord, power adapter, and the power outlet.
• If the problem persists, please contact the original place of purchase for help.
