2.3. How to clean
(1) Use a commercial air blaster to blow dust off the lens and then wipe it softly with a
sheet of lens cleaning tissue (or washed gauze).
Wipe off any fingerprints or oils with a sheet of lens cleaning tissue dampened with
a little absolute alcohol.
(2) Avoid using any organic solvents in the cleaning of any parts other than the lens.
Wipe off heavy dirt, if any, with a soft cloth slightly dampened with diluted neutral
detergent.
Absolute alcohol is highly flammable. Never place the device near
an open flame when using absolute alcohol, and do not handle any
electrical device switches that may cause ignition. In addition, make
sure there is sufficient ventilation in the room. Before conducting
maintenance on the lamp house, wait until it is cool enough to
touch.
