Please read the instructions carefully before using.
Cautions
1. Condition the thermometer at room temperature for 30 minutes before taking a reading.
2. Use a new probe cover with each and every measurement to prevent inaccurate readings.
3. Please keep your ear canal clear, if not, the measuring result shall be inaccurate.
4. The
5. Do not scratch the probe membrane as this will affect the accuracy of measurements.
6. If the LCD does not change or respond when you press any of the buttons, remove the batteries
and then replace to reset.
12. This device must always be kept in a clean, dry area.
13.
:
Degree of protection against electric shock is Type BF applied part.
' ' symbol on the display indicates the device is ready for use.
14.
Battery disposal should be completed in accordance with local regulations.
:
7. Please don't use the thermometer if your ear canal has become inflamed. Do not force the thermometer
into the ear canal. If pain occurs, stop using immediately.
8. Do not expose this thermometer to electric shock.
9. Do not expose the thermometer to sunlight or to water.
10. Do not use near strong electromagnetic fields, i.e. Keep it away from any radio systems and mobile phones.
11. Do not modify this device without authorization of the manufacturer.

The standard we adopted is EN12470-5:2003 Clinical thermometers -- Part 5: Performance of infrared
ear thermometers (with maximum device).
This device complies with the requirements of IEC 60601-1,IEC 60601-1-11 and IEC 60601-1-2.
Guidance and manufacturer's declaration - electromagnetic immunity
The IET2 Device is intended for use in the electromagnetic environment specified below.
The customer or the user of the IET2 Device should assure that it is used in such an environment.

Portable and mobile RF communications equipment should
be used no closer to any part of the
IET2 Device,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance :
Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation distance
in meters (m).Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be
less than the compliance level in each frequency range.

NOTE 1: At 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. 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 the
oretically 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
IET2 Device is used exceeds the applicable RF compliance level above, the IET2 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 IET2 Device.
B. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
The IET2 Device is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the IET2 Device can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the IET2 Device as recommended below, according to
the maximum output power of the communications equipment.
