Precautions (continued)
CAUTION:
Use only the battery charger supplied with the meter. Use of
any other charger may damage the battery.
NOTE:
Damage caused by improper cleaning of the display screen
will void the warranty of the unit.
NOTE:
Never use abrasive pads, paper towels, tissue paper, or
clothing to wipe the screen. If you do, these non-ultrasoft
materials can cause permanent damage by scratching the
screen or stripping the anti-glare coating off the screen.
NOTE:
Never use any type of window cleaner, soap, scouring powder,
or any cleanser with solvents such as alcohol, benzene,
ammonia, or paint thinner. These chemicals can react with
the materials used to construct the display which can lead to
hazing, yellowing, brittleness, or other types of damage.
ALERT:
Never spray liquid directly on the display screen as it could
run inside the unit and cause damage.
