CARE AND MAINTENANCE
Your RadioShack System 440 99-Number Memory Call Waiting Caller ID
module is an example of superior design and craftsmanship. The follow-
ing suggestions will help you care for the module so you can enjoy it for
years.
• Keep the module dry. If it gets wet, wipe it dry immediately. Liquids
can contain minerals that can corrode the electronic circuits.
• Handle the module gently and carefully. Dropping it can damage
circuit boards and cases and can cause the module to work improp-
erly.
• Use and store the module only in normal temperature environ-
ments. Temperature extremes can shorten the life of electronic
devices, damage batteries, and distort or melt plastic parts.
• Keep the module away from dust and dirt, which can cause prema-
ture wear of parts.
• Wipe the module with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean it.
