Precautions in preventing
low-temperature burning
Low-temperature burning is a burning that causes symptoms such as
erythema or water blisters when our bodies are exposed to a heating
element which is of a higher-temperature than the body temperature
for a long period. Please take note that there are low-temperature
burnings that do not cause subjective symptoms.
When the external temperature is low, there might be cases where this
product does not warm up fully. In this case, use a special case or cloth to
warp up Kairo so that it is not exposed to external air.
Charging should be carried out at a temperature between
0/40˚C (
32/104
Only the metal parts at the thermal section of this product will become
warm.
Even if the AC adaptor becomes warm while charging, is not a malfunction.
When there is noise coming from a radio or TV while charging, place this
product far away from the radio or TV.
The maintenance shall be carried out with
a dry cloth.
When a wet cloth is used instead, it might
cause a breakdown. In addition, when
alcohol, thinner, benzene or a detergent is
used for cleaning, the printing might be
faded or the color might appear faint.
This product is designed to prevent an increase in heating which is
a main cause of low-temperature burning. However, depending on
individual differences or the way of using it, the possibility of you
suffering from low-temperature burning might differ. Therefore,
please take note of the following points when you use it.
1. Please switch off the Temperature switch.
2. Plug the DC connector of the AC adaptor into the DC
input jack of Kairo.
Make sure that the DC connector is plugged in all
the way.
3. Unfold the AC plug of the AC adaptor in the direction
of the arrow and insert it into an electrical outlet (see
the illustration below). The Luminescent Display
lights up in green, indicating that the charging has
started.
Make sure that the AC adaptor is plugged into an
AC outlet.
Charging time: About 3 hours
4. When the charging is complete, the green light on the
Luminescent Display disappears.
5. After Kairo is charged, pull out the AC plug of the AC
adaptor from the outlet and fold it. Then pull out the
DC connector from Kairo
Operating Kairo
1. Please switch on the Temperature switch.
Confirm that the luminescent display blinks slowly
in either red or orange.
When the luminescent display blinks in red (at
around every 0.5 second), there is either a tempera-
ture protection or abnormality in the equipment.
This should be dealt with by Troubleshooting.
Please see "When you believe that a breakdown
has occurred" on page 11 and follow the instruc-
tions.
2. When you want to stop using Kairo, please switch off
the Temperature switch.
Persistent switching of tempreture on/off function
will consume electricity quickly and shorten usage
time. In such a case, please charge Kairo as soon as
possible.
*Even if the temperature switch is turned on during
charging, Kairo does not become warm. Please
stop charging Kairo before you start using it.
• Do not expose your skin by putting Kairo in the special case for a
long period.
• Confirm your skin condition every one hour. If you find some
abnormalities on you skin, stop using it immediately.
• Stop using it when you feel too hot.
•� Do not use it when you sleep because you are prone to suffer
from low-temperature burning while sleeping.
•� Take note of low-temperature burning especially for those whose
skins are sensitive, or for infants or handicapped people.
• Take note when you use it on thin clothing such as underwear.
• Do not use it near heating equipment or a stove because it is
very hot.
• Do not use it if you have blood circulation problems such as
having diabetes since you might suffer from low-temperature
burning.
