• Never press the keys of the calculator with a ballpoint
pen or other pointed object.
• Use a soft, dry cloth to clean the exterior of the
calculator.
If the calculator becomes very dirty, wipe it off with a cloth
moistened in a weak solution of water and a mild neutral
household detergent. Wring out all excess liquid before
wiping the calculator. Never use thinner, benzene or other
volatile agents to clean the calculator. Doing so can
remove printed markings and can damage the case.
