Product Notes and Precautions1.5
Please read the following precautions to avoid fire, excessive heat, chemical
leakage and explosion.
Do not disassemble or modify the battery.
Do not expose the battery to heat (fire) or water/moisture.
When disposing used/old batteries, wrap with insulation tape to shield
the battery from electrical contact with metallic objects, which might
ignite a fire or explosion.
If the unit is plugged into the power adapter and the battery seems to be
overheating, or if there is smoke or peculiar odors emanating from the
unit, unplug immediately to avoid the possibility of fire.
However, do not touch the cables if there is heat emanating from near the
cables as melted or deformed cables could expose wiring and result in
burns or electric shock.
Do not use cloth or anything to wrap or cover the equipment while
charging – this could cause the unit to overheat, melting the casing or
causing fire.
If the unit is accidently immersed in water, or if moisture has seeped
inside, or metal objects have dropped into the casing, immediately
remove the battery to avoid fire or electric shock.
Do not operate or store the battery in high-temperature environments -
it will cause battery leakage and/or shorten the life of the battery .
Do not use paint thinner, benzene or other organic solvents to clean the
equipment – this may damage the exterior finish or touch screen, and
may even ignite fire.

Precautions / Warnings
The MK350N PLUS LED Meter contains sensitive components.
Please unpack with care, as any trauma to the unit may damage
the equipment. Contact your agent if the unit appears not to
be operating normally. Do not attempt any repairs – all repairs
must be performed by qualified service agents.
2. Most LCD screens have a very small and inconsequential
defective pixel rate (usually less than 0.1%). This results in
occasional pinpoints of white or other colors but will not affect
the accuracy of measurements.
