Please read all instructions carefully and thoroughly
before using this product.
The DET-306b infrared forehead thermometer is specifically designed
for safe use on the forehead. The Infrared Forehead Thermometer is
a device capable of measuring people's body temperature by
detecting the intensity of infrared light emitted from the forehead.
It converts the measured heat into a temperature reading displayed
on the LCD. The infrared forehead thermometer is intended for the
intermittent measurement of human body temperature from the skin
surface of forehead by people of all ages. When properly used, it will
quickly assess your temperature in an accurate manner.

Forehead Thermometer Advantages
Infrared Forehead Thermometer measures core body temperature,
which is the temperature of a body's vital organs. (See Figure 1)
This thermometer is designed to measure the temperature of the
skin surface over the temporal artery, a major artery of the head.
The temporal artery is connected to the heart via the carotid artery,
directly leading from the aorta, the main trunk of the arterial system.
It offers constant blood flow. Therefore, body temperature changes
are reflected sooner in the forehead than they are in other parts of
the body such as oral, rectal and underarm.

Object Mode
The object mode shows the actual, unadjusted surface
temperatures, which is different from the body temperature. It can
help you to monitor if the object temperature is suitable for the baby
or patient, for example the baby's milk.
→ Please see the section to learn how to
measure the object temperature.
Illustration For Use
The real time clock will be recorded with the memory function and
help you to recognize each measurement result.
→ Please see the Real time clock setting section to learn how to
setup the time in the first use.
The thermometer has been designed for practical use. It's not
meant to replace a visit to the doctor. Please also remember to
compare the measurement result to your regular body temperature.

Memory Mode
There are each 10 sets memories for forehead and object
measurements. Each memory also records the measurement

Real Time Clock Setting Real Time Clock Setting
To ensure that the reading always reflects the body temperature
accurately, you need to take account of the following factors which
may affect an accurate reading.
1. It is important to know each individual's normal temperature
when they are well. This is the only way to accurately diagnose
a fever. To determine normal temperature, take multiple readings
when healthy. Re-measure with a standard digital thermometer
for confirmation.
2. Users
3.
. Oils or cosmetics on the forehead may give a lower temperature
reading than the actual one.
must be inside for 30 minutes before taking a measurement.
Note: Users and the thermometer should be in the same ambient
temperature for at least 10 minutes before taking a reading.
Users should not drink, eat, or be physically active such as
bathing, showering, shampooing and hair drying before/while
taking the measurement. Remove hat and hair and wait 10 minutes
before taking a reading.
4
Remove dirt from the forehead before
taking a measurement. Wait at least 10 minutes after washing the
forehead area before taking a reading.
Temperature Taking Hints Temperature Taking Hints
5. Holding a hand on the forehead for any length of time will affect
the temperature reading.
6. Do not take temperature over scar tissue, open sores or abrasions.
7. Do not use the thermometer on a perspiring or sweating forehead,
as this may affect the reading.
8. Don't take a measurement while or immediately after nursing a
baby.
9. Do not take temperatures with this thermometer near places that
are very hot, such as fireplaces and stoves.
10. The probe window of the thermometer is the most delicate part
of the device. Do not touch the probe window. The accuracy of
the reading may be affected if the probe window is damaged or
dirty.
11. If the thermometer is stored in a significantly different
environment than testing location, place it in the testing location
for approximately 30 minutes prior to use.
12. It is not intended for use in the oxygen rich environment and
presence of flammable anesthetic mixture with air, oxygen or
nitrous oxide.

Care And Cleaning
1. The probe window must be kept clean, dry, and undamaged at all
times to ensure accurate readings. The accuracy of temperature
readings can be affected by damage to the probe window, or the
presence of dirt, fingerprints, earwax, dust and other soiling
compounds on the probe window. Degraded sensors can degrade
performance or cause other problems.
2. The probe window is the most delicate part of the thermometer.
Use a soft cloth slightly moistened with a 75% isopropyl alcohol
solution to disinfect probe window and the thermometer. Do not
use abrasive cleaners. After cleaning, allow at least 10 minutes
drying time before taking temperatures.
Note: Do not use any chemical other than isopropyl alcohol to
clean the probe window.
3. Use a soft, dry cloth to clean the thermometer display and
exterior.
4.
5. Store the thermometer in a dry location, free from dust and
contamination and away from direct sunlight.
6. Strong electromagnetic fields may interfere with the proper
operation of the thermometer. The device needs special
pre-cautions regarding EMC according to the EMC information.
Do not put the thermometer into water directly.
7. Put the thermometer back to the original packaging after using.

NOTE 1At 80 MHz and 800 MHz, the higher frequency range applies.NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
a The ISM(industrial, scientific and medical) bands between 0,15 MHz and 80 MHz
are 6,765 MHzto6,795 MHz;13,553 MHz to 13,567 MHZ;26,957 MHz to 27,283
MHz; and 40,66 MHz to 40,70 MHz. The amateur radio bands between 0,15 MHz
and 80 MHz are 1,8 MHz to 2,0 MHz,3,5 MHz to 4,0 MHz,5,3 MHz to 5,4 MHz,7

b The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz
and in the frequency range 80 MHz to 2,7 GHz are intended to decrease the
likelihood that mobile/portable communications equipment could cause
interference if it is inadvertently brought into patient areas. For this reason, an
additional factor of 10/3 has been incorporated into the formulae used in
calculating the recommended separation distance for transmitters in these
frequency ranges.
c Field strengths from fixed transmitters, such as base stations for radio(cellular/
cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in
the location in which the device is used exceeds the applicable RF compliance level
above, the device should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
re-orienting or relocating the device.
d Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3 V/m.
