MAINTENANCE
Your Optimus CTR-107 Portable Cassette Tape Re-
corder is an example of superior design and crafts-
manship. The following suggestions will help you care
for your CTR-107 so you can enjoy it for years.
• Keep the CTR-107 dry. If it gets wet, wipe it dry
immediately. Liquids can contain minerals that
corrode electronic circuits.
• Use and store the CTR-107 only in normal tem-
perature environments. Temperature extremes
can shorten the life of electronic devices, dam-
age batteries, and distort or melt plastic parts.
• Handle the CTR-107 gently and carefully. Drop-
ping it can damage circuit boards and cases and
can cause the CTR-107 to work improperly.
• Keep the CTR-107 away from dust and dirt,
which can cause premature wear of parts.
• Use only fresh batteries of the recommended
size and type. Old batteries can leak chemicals
that can damage your CTR-107’s electronic cir-
cuits.
• Wipe the CTR-107 with a damp cloth occasion-
ally to keep it looking new. Do not use harsh
chemicals, cleaning solvents, or strong deter-
gents to clean your CTR-107.
