Care; Service And Repair - Radio Shack 43-3578 Owner's Manual

If you still have problems, disconnect the phone. If other phones
on the same line work properly, the fault is in this phone or its
installation. If you cannot find the problem, take the phone to your
local RadioShack store for assistance.

CARE

Keep the phone dry; if it gets wet, wipe it dry immediately. Use
and store the phone only in normal temperature environments.
Handle the phone carefully; do not drop it. Keep the phone away
from dust and dirt, and wipe it with a damp cloth occasionally to
keep it looking new.

SERVICE AND REPAIR

If your phone is not performing as it should, take it to your local
RadioShack store for assistance. Modifying or tampering with the
