CARE AND MAINTENANCE
RESETTING THE UNIT
If the unit is exposed to a strong static electrical charge, the unit
may lock up, or the display may dim. This is very rare, but if it
does happen, remove the batteries and then reinstall. All
settings will return to their preset values, but the previous
messages are saved.
TRAFFIC SAFETY
• Do not use while operating a motorized vehicle. It may create
a traffic hazard and is illegal in many areas.
• Even if your earphone is an open air type designed to let you
hear outside sounds, do not turn the volume up so high that
you cannot hear what is around you.
• Use extreme caution or temporarily discontinue use in
potentially hazardous situations.
CARE
• Keep the unit dry. If it gets wet, wipe it immediately. Liquids
may contain minerals that can corrode the circuits.
• Use and store the unit only in normal temperature
environments. Extreme temperatures can shorten the life of
electronic devices, damage batteries and/or melt plastic parts.
• Keep the unit away from dirt and dust.
• Handle the unit gently and carefully. Dropping it can cause
damage and may cause the unit to work improperly.
• To clean, wipe the unit with a damp cloth occasionally to keep
it looking new. Do not use harsh chemicals, cleaning solvents
or strong detergents.
