• Take care not to drop your calculator or allow it to receive any other impacts.
• Do not leave your equipment in areas exposed to dampness, dirt, dust or high

• Never dispose of batteries, the liquid crystal panel, or other component in a fire.
• Should the calculator be exposed to a high electrostatic discharge, the content of the
memory could suffer damage or the keys could stop working.
• Before assuming malfunction of the equipment, make sure you have read this
instruction manual and check that the problem is not caused by the batteries running out
or by calculation errors.
