ˆCare

Your Nexxtech 12-Digit Dual Power Metal Top Desk Calculator is an ex- ample of superior design and crafts- manship. The following suggestions will help you care for your calculator so you can enjoy it for years.

Keep the calculator dry. If it gets wet, wipe it dry immediately. Liq- uids might contain minerals that can corrode the electronic cir- cuits.

Use and store the calculator only in normal temperature environ- ments. Temperature extremes can shorten the life of electronic devices, damage the battery, and distort or melt plastic parts.

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

Handle the calculator gently and carefully. Dropping it can dam- age circuit boards and cases and can cause the calculator to work improperly.

Use only a fresh battery of the required size and type. Batteries can leak chemicals that damage your calculator’s electronic parts.

Wipe the calculator with a damp cloth occasionally to keep it look- ing new. Do not use harsh chem-

icals, cleaning solvents, or strong detergents to clean the calcula- tor.

Modifying or tampering with the cal- culator’s internal components can cause a malfunction and invalidate the calculator’s warranty. If the calcu- lator is not performing as it should, take it to your local electronic store for assistance.

REPLACING THE

BATTERY

Although your calculator is solar pow- ered most of the time, the supplied back-up battery might eventually weaken and need replacing. If the display speed slows down in low light, replace the 389A battery. For the best performance and longest life, we rec- ommend alkaline batteries.

Warnings:

Keep button-cell batteries away from children. Swallowing a but- ton-cell battery can be fatal.

Dispose of an old battery promptly and properly. Do not burn or bury it.

Caution: Use only a fresh battery of the required size and recommended type.
