Swimming pool or in a wet basement.
lDo not place the monitor on an unstable trolley, stand, or table. If the monitor falls, it can injure a person and cause
serious damage to the appliance. Use only a trolley or stand recommended by the manufacture or sold with the
monitor. If you mount the monitor on a wall or shelf, use a mounting kit approved by the manufacture and follow the
kit instructions.

type of power supplied to your home, consult your dealer or local power company.
lThe monitor is equipped with a three-pronged grounded plug, a plug with a third (grounding) pin. This plug will fit
only into a grounded power outlet as a safety feature. If your outlet does not accommodate the three-wire plug, have
an electrician install the correct outlet, or use an adapter to ground the appliance safely. Do not defeat the safety
purpose of the grounded plug.
