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.

Temperature Taking Hints
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.
- 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.
- Users 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.
- Oils or cosmetics on the forehead may give a lower temperature reading than the actual one. Remove dirt from the forehead before taking a measurement. Wait at least 10 minutes after washing the forehead area before taking a reading.
- Holding a hand on the forehead for any length of time will affect the temperature reading.
- Do not take temperature over scar tissue, open sores or abrasions.
- Do not use the thermometer on a perspiring or sweating forehead, as this may affect the reading.
- Don’t take a measurement while or immediately after nursing a baby.
- Do not take temperatures with this thermometer near places that are very hot, such as fireplaces and stoves.
- 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.
- 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.
- It is not intended for use in the oxygen rich environment and presence of flammable anesthetic mixture with air, oxygen or nitrous oxide.

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

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.
Table 4

portable and mobile RF communications equipment and the device
The device is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the
device can help prevent electromagnetic interference by maintaining a minimum
