Troubleshooting
FAQ 1: The temperature cannot be displayed, and the full-screen display is repeated after
booting. What is the cause?
Answer: If this kind of problem occurs in the Infrared thermometer, it can be basically
determined that the battery is low. You can try to replace the battery with a new one.
FAQ 2: When some people's body temperature is measured in the same environment, if the
screen displays "Lo", what is the reason?
Answer: The possible causes to be excluded are as follows:
1. When the person's forehead is covered with hair or sweat, the patient had been pasted
with antipyretic paste or taken antipyretic drugs, or the forehead is pointed at the air conditioner
and strong wind is blown across the surface, "Lo" may appear. Please have a rest in a stable
environment for 5-10 minutes before measuring.
2. A: There are extremely few people whose surface temperature is lower than other people. If
an individual shows "Lo" for each measurement, you can compare the forehead temperature with
the back of the hand with others, and then test the body temperature of other people for comparison.
B:When the body temperature of an individual (not all human bodies) appears "Lo", it can be
deemed as a normal body temperature. The main concern is the over-temperature prompt ( "HI").
The appearance of "Lo" indicates that the surface temperature of the forehead of the human body
is very low at this time, which is beyond the display range of the product. The main reasons why the
screen shows Lo:
Reasons why the screen shows Lo Advice
There is hair or sweat on the forehead when reading
temperature.
Make sure there are no obstacles on the
forehead
Cold air blows forehead Make sure no cold air is blowing directly on the
forehead
10
Forehead just cold applied Wait for 10 minutes after cold compress before
measuring.
The measurement distance is too long Recommended measurement distance is 3-5cm
FAQ 3: Is the product harmful to the human body and is it radiating to the human body?
Answer: The principle of the product is to calculate the body temperature of the human body
by collecting the infrared radiation of the human body. The product does not directly contact
the human body and does not cause cross infection of dierent human bodies. Therefore, it is
harmless to the human body, so please rest assured that the use of.
FAQ 4: What is the dierence between an Infrared thermometer and a mercury thermometer?
Answer: 1. The Infrared thermometer is non-contact type. The mercury thermometer needs to
directly contact the human body, which is likely to cause cross infection between dierent human
bodies.
2. The mercury thermometer has a long measurement time, which makes it not easy to
read and not safe, especially when measuring the temperature of children, it is not easy to pinch
because children are active, which brings great inconvenience to parents.

Portable and mobile RF communications
equipment should not be used closer than
the recommended separation distance to
any part of WT-1, including cables. The
separation distance should be calculated
from the corresponding formula of
transmitter frequency.
Recommended separation distance:
d=1.2/P
d=1.2/P 80MHz ～800MHz
d=2.3/P 800MHz ～2.5GHz
P is the maximum rated power output
of the transmitter in Watts (W) provided
by transmitter manufacturer. d is the
recommended separation distance in
meters (m).
As field strength from fixed RF
transmitters is determined by an
electromagnetic site survey a, therefore it
should be less than the compliance level
in each frequency range.
Interference may occur near the device
marked by the following symbols.
Note 1: At 80MHz and 800MHz frequency, adopt formula of higher frequency range.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reection from buildings, objects, and human body.

a. Field strengths from xed 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 xed RF transmitters, an
electromagnetic site survey should be taken into consideration. If the measured eld strength in the location
where WT-1 is used exceeds the applicable RF compliance level above, the WT-1 should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the WT-1.
b. Over the frequency range 150kHz to 80MHz, eld strengths should be less than 3V/m.
Recommended separation distance between portable and mobile RF communications equipment and the
WT-1.
WT-1 is intended for being used in electromagnetic environment where radiated RF disturbance is
controlled. As per the maximum power output of communication device, the customer or user of WT-1 can
help to prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communication device (transmitter) and WT-1 recommended below.
