INTRODUCTION
Thank you for choosing RT-1241 Thermometer. Please read this
and correctly. Please keep this instruction manual for future refer-
ence. This innovative medical device uses advanced infrared (IR)
technology to measure temperature instantly and accurately on the
forehead/surface.
Intended Use
RT-1241 Thermometer is intended for the intermittent measurement
and monitoring of human body temperature from forehead measure-
ment at home. The device is intended for use by people of all ages
in the home.
How does it work
The thermometer measures the infrared heat generated by the
surface of the skin over the vessel and its surrounding tissue. The
thermometer then converts it into a temperature value.
The thermometer does not emit any infrared signal.
NOTE

7
ASTM E1965-98 and the EC directive 93/42/EEC.
Non-contact measurement that does not require probe cover,
thereby saving cost of replacement.
Automatically power off if left idle for 30 seconds.
Memory function allows you to recall previous results up to 10
previous results.
Easy to read LCD with backlight in a dark environment.
Able to measure temperature of other objects without contact and
room temperature.

Body temperature can vary from one individual/person to next. It
also varies by location on the body and time of day. Below shows
the statistical normal ranges from different sites. Please keep in
mind that temperatures measured from different sites, even at the
same time, should not be directly compared. Fever indicates that
the body temperature is higher than normal. This symptom may be
caused by infection, overdressing or immunization. Some people
may not experience fever even when they are ill. These include, but
are not limited to, infants younger than 3 months old, persons with
compromised immune systems, persons taking antibiotics, steroids
or antipyretics (aspirin, ibuprofen, acetaminophen), or persons with
certain chronic illnesses. Please consult your physician when you
feel ill even if you do not have fever.
