General Care
Do not store or leave the oscilloscope where the LCD display will be exposed to direct
sunlight for long periods of time.
Caution: To avoid damage to the oscilloscope or probes, do not expose them to sprays,
liquids, or solvents.
Cleaning
Inspect the oscilloscope and probes as often as operating conditions require. To clean the
exterior surface, perform the following steps :
1. Remove loose dust on the outside of the oscilloscope and probes with a soft cloth.
When cleaning the LCD, use care to avoid scratching the clear protection film of the
LCD.
2. Use a dampened but not dripping soft cloth to clean the oscilloscope. Remember to
disconnect power. Use a mild cleaner or water. To avoid damaging the product or
probe, do not use abrasive chemical cleaner.
Warning : To avoid short circuit or personal injury due to the presence of moisture,
please ensure the product is completely dry before reconnecting power for operation.
