Handling Tips
This monitor is a precision instrument utilizing state-of-the-art technology. To keep the unit
in the best condition, follow these instructions carefully:
• Do not attempt to disassemble the measuring platform.
• Store the unit horizontally, and place it so that the Personal keys will not be
pressed accidentally.
• Avoid excessive impact or vibration to the unit.
• Place the unit in an area free from direct sunlight, heating equipment, high humidity, or
extreme temperature change.
• Never submerge the unit in water. Use alcohol to clean the electrodes and glass cleaner to
keep them shiny, applied to a cloth first; avoid soaps.
• When you change the batteries, exchange all four at the same time with new
AA-size batteries.
