CARE

Your RadioShack EC-3031 Handheld Printing Calculator is an example of su- perior design and craftsmanship. The following suggestions will help you care for the calculator so you can enjoy it for years.

Keep the calculator dry. If it gets wet, wipe it dry immediately. Liq- uids can contain minerals that cor- rode the electronic circuits.

Handle the calculator gently and carefully. Dropping it can damage the circuit board and case, and can cause the calculator to work improperly.

Keep the calculator away from dust and dirt, which can cause prema- ture wear of parts.

Wipe the calculator with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong deter- gents to clean the calculator.

Use and store the calculator only in normal temperature environments. Temperature extremes can short- en the life of electronic devices, damage batteries, and distort or melt plastic parts.
