MAINTENANCE
• Keep the PVCO dry. If it gets wet, wipe it dry immediately. Liquids might
contain minerals that can corrode the internal electronic components.
• Use and store the PVCO only in normal temperature environments. Extreme
temperatures can shorten the life of electronic components, damage batteries,
distort and possibly melt plastic parts.
• Handle the PVCO with care. Dropping it can cause internal working parts to
fail or break the outer housing.
• Keep the PVCO away from dust and dirt, which can cause premature
wear of parts.
• Clean the PVCO by wiping the unit with a damp cloth to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong detergents to
clean the PVCO.
• When replacing the batteries, use only alkaline AAA batteries. Always
remove old or weak batteries. Batteries can leak chemicals that can harm or
destroy internal electronic components.
