formance of procedures other than those specied here may result in
exposure to hazardous radiation.
CAUTION
• Do not block the ventilation openings or holes.
• Do not place any naked ames (such as lighted candles) on the ap-
paratus.
• When discarding batteries, follow all local rules and laws governing the
disposal of batteries. Consider the environmental impact of your actions!
