1. Safety information
1.1. General information
Purpose of use
•This Operation manual contains how to use BT-
36, Contactless infrared
thermometer of Bistos Co. Ltd. So please read this manual before use the device.
•BT-
36 is contactless thermometer that can safely measure body temperature from
inconvenient by body insertion, skin contact or risk of infection by detecting
infrared emitted from the skin and measures body temperature.
•
In general, body temperature refers to the internal temperature of the human
body. Body temperature varies depending on the part of the body being
measured, the time of the day being measured, the ambient temperature, the
activity just before the measurement, and the age etc.
•
The surface temperature of human body is lower than actual body temperature.
BT-
36 displays calibrated oral temperature by rewarding from measured skin
temperature in body temperature measurement mode.
•The recommended part of BT-36 body temperature measurement mode is from 2
~ 5 cm by the center of forehead.
•BT-
36 operates with 2 kinds of measurement mode(body & object temperature),
it can measure temperature within a second and continue measuring temperature
directly after finishing former measurement.
•
This device doesn’t need any special training or education. Anyone can use the
device easily if the user knows how to use it.
•Y
ou can see the normal temperature range according to each body part by the
table below.
Body Part Normal Temperature Range
Ear (tympanic) 35.8℃~ 38.0℃(96.44℉~ 100.4℉)

5. Trouble shooting
Problem Solution
The power does not
turned on.
•Check the battery charging status.
•Check the status of the battery insertion in the main body.
The main body gets
wet
•Remove the batteries from main body.
•Wipe the body with a dry cloth and store it in a warm and
dry place for at least 12 hours.
If the measurement
is not working
properly
•W
hen measuring infants or children, if they struggle too
much, measurement errors may occur because the distance
between the skin surface and the sensor may not be
constant, so please measure again after they calm down.
•It is recom
mended to measure body temperature after
stabilizing at room temperature(15~25℃, 59℉~77℉).
•T
emperature measurements may be inaccurate if measuring
temperature immediately after exercise, come back from
outside, or taking a bath, and measurements may also be
inaccurate when measuring outside instead of indoors.
•F
or accurate measurement, remove hair, foreign substances,
or makeup between the thermometer and the skin.
•I
f the battery is not replaced when the low battery icon in
displayed on the LCD screen, the
measurement value may
not be accurate.
•
If user measure temperature close from air conditioner, fan,
heater, it may cause inaccurate results.
※If the problem is not solved or have additional questions, please contact the Bistos Co., Ltd.
service center.
