CAUTION
• While the device is not in use, turn it off.
• The LM-600P/LM-600PD uses a heat-sensitive printer paper. To keep the printed data
for a long period of time, make copies of the printouts.
The paper degrades over time and the printed data may become illegible.
• Do not yank the power cord to disconnect it from an outlet but hold the plug.
This can damage the metal core of the cord and may result in electric shock, short cir-
cuit, or fire.
• Occasionally clean the prongs of the mains plug with a dry cloth.
If dust settles between the prongs, the dust will collect moisture, and short circuit or fire
may occur.
• If the device will not be used for a long time, disconnect the power cord from the wall
outlet.
