Handling Precautions

•The EA-200 is made up of precision components. Never try to take it apart.

•Avoid dropping the EA-200 and subjecting it to strong impact.

•Do not store the EA-200 or leave it in areas exposed to high temperatures, humidity, low temperatures, or large amounts of dust. Low temperatures can shorten battery life.

•Replace the main batteries once every two years regardless of how much the EA-200 is used during that period. Never leave dead batteries in the battery compartment. They can leak and damage the unit.

•Keep batteries out of the reach of small children. If swallowed, consult with a physician immediately.

•Avoid using volatile liquids such as thinner or benzine to clean the unit. Wipe it with a soft, dry cloth, or with a cloth that has been dipped in a solution of water and a neutral detergent, and wrung out.

•In no event will the manufacturer and its suppliers be liable to you or any other person for any damages, expenses, lost profits, lost savings or any other damages arising out of loss of data and/or formulas arising out of malfunction, repairs, or battery replacement. The user should prepare physical records of data to protect against such data loss.

•Never dispose of batteries, or other components by burning them.

•Replace batteries as soon as possible after the low battery indicator lamp (Batt) lights.

•Be sure that the power switch is set to OFF when replacing batteries.

•If the EA-200 is exposed to a strong electrostatic charge, its memory contents may be corrupted or the keys may stop working. In such a case, perform the Reset operation to clear memory contents and restore normal key operation.

•If you start to experience serious operational problems with the EA-200, use a thin, pointed object to carefully press the P button on the back of the EA-200. Note, however, that pressing the P button deletes all data currently in EA-200 memory. Proper operation does not resume after you press the P button, remove its batteries, and then replace them correctly in accordance with the instructions on page 0-3 of the User’s Guide.

•Note that strong vibration or impact during program execution can cause execution to stop or can corrupt EA-200 memory contents.

•Using the EA-200 near a television or radio can cause interference with TV or radio reception.

•Before assuming malfunction of the EA-200, be sure to carefully reread this User’s Guide and ensure that the problem is not due to insufficient battery power, programming or operational errors.

•Never allow foreign objects to get into connector holes. Doing so can result in malfunction.

•Always make sure to connect probes only to their correct terminals. Never force the plug of a probe into a wrong terminal connector.

•Be sure to turn the EA-200 off before connecting or disconnecting probes.

•Make sure that probes are connected securely before using them to take samples.

•Never insert a probe into an electric outlet. Never attempt to measure high voltages or household AC. Doing so creates the danger of electric shock.

•Never apply more than 15V to analog channels CH1 or CH2, more than 5V to analog channel CH3, or more than 5.5V to the SONIC, DIG IN, or DIG OUT channels. Doing so can damage the EA-200.

•The EA-200 is to be used for educational purpose only. It is not appropriate for industrial, research, medical, or commercial applications.
