Do not put or leave the device in a place where the LCD display will be exposed to direct sunlight for long periods of time.
Note: To avoid damage to the oscilloscope or probes, do not expose them to sprays, liquids, or solvents.
Examine the oscilloscope and probes as often as operating conditions require. To clean the exterior surface, perform the following steps:
1. Use a lint-free cloth to remove floating dust on the outside of the oscilloscope and probes. Take care to avoid scratching the glabrous display filter.
2. Use a soft cloth dampened with water to clean the oscilloscope. For more efficient cleaning, you may use an aqueous solution of 75% isopropyl alcohol.
Note: To avoid damage to the surface of the oscilloscope or probes, do not use any corrosive or chemical cleaning agents.
