5Power and Ground Connection Cautions
Ensure that the plug connection is free of dust. In a damp environment, a contaminatedconnector can draw a significant amount of current that can generate heat andeventually cause fire over an extended period of time.Always use the power cord provided with your machine. When an extension power cordis required, always use a properly rated cord.
120 V/15 A or AC 220 - 240V/10 AIf you use a cord with an unspecified current rating, the machine or plug may emit smokeor become hot to the touch externally.
Do not attempt to rework, pull, bend, chafe or otherwise damage the power cord. Do notplace a heavy object on the cord. A damaged cord can cause fire or electric shocks.
For Your SafetyTo prevent severe injury and loss of life, read this section carefully before servicing the Panasonicmachine to ensure proper and safe operation.Please ensure that the machine is installed near a wall outlet and is easily accessible.
