Surge Protection; Fcc Information - Radio Shack 43-3905 User Manual

Surge Protection

Your telephone has built-in protection circuits to reduce the
risk of damage from surges in telephone line and power line
current. These protection circuits meet or exceed the FCC
requirements. However, lightning striking the telephone or
power lines can damage your telephone. Lightning damage is
not common. Nevertheless, if you live in an area that has severe
electrical storms, we suggest that you unplug your phone when
storms approach to reduce the possibility of damage.
