AC Adapter
● Never use a voltage that is different from that for which the AC adapter is
rated. Also, do not plug the unit into a power outlet that is shared by other
devices. Doing so creates the danger of fire and electrical shock.
● Never modify the power cord or excessively bend, twist, or pull it. Doing so
creates the danger of fire and electrical shock.
● Do not allow the power cord to become damaged. Do not place heavy objects
on the power cord or expose it to heat. A damaged power cord creates the
danger of fire and electrical shock.
● Never touch the AC adapter while your hands are wet. Doing so creates the
danger of electrical shock.
● Should the power cord ever become seriously damaged (internal wiring
exposed or shorted), contact your original dealer or an authorized IRIS
service provider to request for servicing. Continued use of a seriously
damaged power cord creates the danger of fire and electrical shock.
● Use only the AC adapter specified for this unit. Use of another type of AC
adapter can damage the battery pack and create the danger of fire and
personal injury.
Warning
● Never charge the battery pack near a stove, under direct sunlight, in an
automobile parked in the sun, or any other area subject to high temperatures.
High temperature can cause the battery pack's safety mechanism to operate
making it impossible to achieve a full charge. Heat can also cause an
abnormal chemical reaction, which creates the danger of fire and explosion.
● Never pierce the battery pack with nails, hit it with a hammer, step on it, or
throw it. Doing so can cause internal shorting, which creates the danger of
fire and explosion.
● Never use a battery pack whose exterior is extremely damaged or deformed.
Use of such a battery pack creates the danger of fire, overheating, and
explosion.
● Never use the battery pack with any device other than this product. Doing
so will cause abnormal current that damages the battery pack and creates
the danger of fire.
● Never expose the battery pack to direct flame, do not throw it into fire, fresh
water, or seawater. Doing so can damage the built in safety and protection
mechanisms, and cause battery fluid to ignite, creating the danger of fire
and explosion.
● If the battery pack does not achieve full charge after the normal charge
time, stop charging. Continued charging creates the danger of fire,
overheating, and explosion.
Warning
Danger

SAFETY PRECAUTIONS

www.iris.com.my
● Unplug the AC adapter from the wall outlet whenever leaving the unit
unattended for long periods.
● At least once a year, unplug the AC adapter from the power outlet and clean
the area around the prongs of the plug. Dust build up around the prongs
can create the danger of fire.
● Be sure to unplug the AC adapter from the wall outlet before attempting to
move the unit to another location.
● Be sure to grasp the AC adapter when unplugging it from a wall outlet.
Pulling on the power cord can damage it, and create the danger of fire and
electrical shock.
● Keep the power cord away from stoves and other sources of heat. Heat can
melt the insulation of the power cord and create the danger of fire and
electrical shock.
Display Screen Precautions
● Never apply strong pressure to the LCD screen or subject it to strong impact.
Doing so can cause the LCD panel glass to crack or break.
● Should the LCD panel glass ever crack or break, never touch the liquid
inside of the panel. LCD liquid can lead to skin irritation.
● Should LCD panel liquid ever get into your mouth, gargle with water and
contact your physician immediately.
● Should LCD panel liquid ever get into your eyes or onto your skin, flush the
exposed area with clean water for at least 15 minutes, and then contact
your physician.
