TAKING CARE OF YOUR TELEPHONE
Your VT 9121 cordless telephone contains
sophisticated electronic parts so it must be
treated with care.
Avoid rough treatment
Place the handset down gently. Save the
original packing materials to protect your
telephone if you ever need to ship it.
Avoid Water
Your telephone can be damaged if it gets wet.
Do not use the handset outdoors in the rain,
or handle it with wet hands. Do not install
your base unit near a sink, bathtub or shower.
Remember that electrical appliances can
cause serious injury if used when you are wet
or standing in water. If your base unit should
fall into water, DO NOT RETRIEVE IT UNTIL
YOU UNPLUG THE POWER CORD AND
TELEPHONE LINE CORDS FROM THE
WALL . Then pull the unit out by the
unplugged cords.
Electrical Storms
Electrical storms can sometimes cause power
surges harmful to electronic equipment.
For your own safety, use caution when using
electric appliances during storms.
Cleaning your telephone
Your telephone has a durable plastic casing
that should retain its luster for many years.
Clean it only with a soft cloth slightly
dampened with water or a mild soap. Do not
use excess water or cleaning solvents of any
kind.
