IV. IMPORTANT NOTICE
• Keep the tester dry. Precipitation and all types of
liquids or moisture can contain minerals that will
corrode electronic circuits. If your tester gets wet,
remove the battery, and allow the tester to dry
completely before replacing it.
• Do not use, store or expose the tester in dusty, dirty
areas. Its moving parts and electronic components can
be damaged.
• Do not use, store or expose the tester in hot areas.
High temperatures can damage or shorten the life of
the tester, damage batteries, and warp or melt certain
plastics.
• Do not use, store or expose the tester in cold areas.
When the tester returns to its normal temperature,
moisture can form inside the tester and damage
electronic circuit boards.
• Do not attempt to open the tester other than as
instructed in this handbook.
• Do not drop, knock, or shake the tester. Rough
handling may break internal circuit boards and fine
mechanics.
• Do not use harsh chemicals, cleaning solvents, or
strong detergents to clean the tester.
