REPLACING THE FUSE

A single 0.75 A 250 V, 3AG fuse (located in the base's battery compartment)
protects the alarm system's burglar and fire alarm capabilities.  If either
alarm stops working, check the fuse and replace with an identical fuse
(Cat. No. 270-1272).

CARING FOR THE SYSTEM

The Radio Shack Wireless Alarm System is an example of superior design
and craftsmanship.  The following suggestions will help you care for the
system so you can benefit from its protections for years.

    Keep the base unit and accessories dry.  If they get wet, wipe them
    dry immediately.  Liquids can contain minerals that can corrode the
    electronic circuits.

    Use and store the base unit and accessories only in normal temperature
    environments.  Temperature extremes can shorten the life of electronic
    devices, damage batteries, and distort or melt plastic parts.

    Handle the base unit and accessories gently and carefully.  Dropping
    them can damage circuit boards and cases, and can cause the base unit
    and accessories to work improperly.

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

    Wipe the base unit and accessories with a damp cloth occasionally to
    keep them looking new.  Do not use harsh chemicals, cleaning solvents,
    or strong detergents to clean the base unit and accessories.

    Uses only fresh batteries of the recommended size and type.  Always
    remove old or weak batteries.  They can leak chemicals that destroy
    electronic circuits.
