CARE AND MAINTENANCE

The following suggestions will help you care for your scan-

ner so you can enjoy it for years.
Keep the scanner dry. If it gets wet, wipe it dry immediately.
Use only fresh batteries of the required size and type. Al-

ways remove old and weak batteries. They can leak chemi-

cals that destroy electronic circuits.
Handle the scanner gently and carefully. Dropping it can

damage circuit boards and cases and can cause the scan-

ner to work improperly.
Use and store the scanner only in normal temperature envi-

ronments. Temperature extremes can shorten the life of elec-

tronic devices, damage batteries, and distort or melt plastic

parts.
Keep the scanner away from dust and dirt, which can cause

premature wear of parts.
Wipe the scanner with a damp cloth occasionally to keep it

looking new. Do not use harsh chemicals, cleaning solvents,

or strong detergents to clean the scanner.
