I. SAFETY PRECAUTIONS
ClinicalGuard.com
- Follow the maintenance advice stipulated in this instruction
manual.
- This device may be used for personal home use.
- This device must only be used for the purposes described in this
instruction manual.
- This device must only be used in an ambient temperature range
of between 50°F and 104°F (10°C and 40 °C).
- This device must always be kept in a clean, dry area.
- Do not expose this thermometer to electric shocks.
- Do not expose this thermometer to extreme temperature
conditions of >122°F (>50°C) or <-4°F (< - 20°C).
- Do not use this device in relative humidity higher than 85%.
- The protective glass over the lens is the most fragile part of the
Thermometer, therefore
- Do not touch the glass of the infrared lens with your fingers.
- Clean the glass with a cotton swab lightly moistened with 70 proof
isopropyl alcohol.
- Do not expose the thermometer to sunlight or to water.
- Do not use this device outside.
- Never drop the device.
- Should a problem occur with your device, please contact your
retailer. Do not attempt to repair this device yourself.

II. INTRODUCTION
ClinicalGuard.com
The OctiveTech FeverWatchers RC802i Non-contact thermometer
was developed using the latest infrared technology. This technology
allows the temporal artery (TA) temperature to be taken at a
distance of approximately 2 inches (5cm) from the forehead.
Precise, instantaneous and without contact, the FeverWatchers
RC802i is, to date, the most suitable thermometer for no risk
temperature measurement. It has been demonstrated that this
method of TA temperature measurement is more precise than
tympanic thermometry and less invasive than rectal thermometry (1).
However, as with other types of thermometers, the FeverWatchers
RC802i must be used properly in order to obtain reliable and stable
results.
You are therefore advised to read the instruction manual and the
safety precautions carefully before use.

Use in Infants. Arch Pediatr Adolesc Med 2001;155:376.
III. PRECAUTIONS BEFORE USE
The FeverWatchers RC802i is pre-set at the factory.
It is not necessary to calibrate the device when
starting it up.
In order to obtain reliable and stable results, you are advised to
allow the FeverWatchers RC802i to acclimate to any significant
changes in the ambient temperature due to a change in environment
for 15 to 20 minutes before using it
It is important to allow a one minute interval between two
measurements.

IV. OPERATING PRINCIPLE
ClinicalGuard.com
All objects: solid, liquid, or gas, emit thermal energy by radiation.
The intensity of this energy depends on the temperature of the
object.The FeverWatchers RC802i infrared thermometer is therefore
able to measure the temperature of a person by the thermal energy
the person emits. This measurement can be taken due to an
external temperature probe on the device which permanently
analyses and registers the directional ambient temperature.
Therefore, as soon as the operator holds the thermometer near the
body and activates the radiation sensor, the measurement is taken
instantly by detection of the infrared heat generated by the arterial
blood flow. Body heat can therefore be measured without any
interference from the heat of the surrounding environment.
THE DIFFERENT METHODS OF TEMPERATURE MEASUREMENT
Core temperature
Core temperature is the most precise measurement and involves
measuring the temperature in the pulmonary artery by means of a
catheter equipped with a thermal probe which can read the
temperature in situ. The same method is employed for probes
measuring the esophageal temperature. However, such invasive
temperature measurement methods require specific equipment and
expertise.
Rectal thermometry
Rectal temperature adjusts slowly in comparison to the changes of
the body’s internal temperature. It has been demonstrated that
rectal temperature remains raised long after the internal
temperature of the patient has started to drop and vice versa.
Furthermore, rectal perforations have been known to occur as a
result of this method and without appropriate sterilization
techniques, rectal thermometry can spread germs often found in
feces.

Oral thermometry
ClinicalGuard.com
Oral temperature is easily influenced by recent ingestion of food or
drinks and by breathing through the mouth. To measure oral
temperature, the mouth must remain closed and the tongue
lowered for three to four minutes which is a difficult task for young
children to accomplish. Use of older technologies such as Mercurybased thermometers pose an additional risk of accidental breakage.
Axillary (armpit) temperature
Although it may be easy to measure axillary temperature, it has
been proven that it does not provide an accurate measurement of
the child’s internal temperature. To take this type of temperature,
the thermometer must be wedged tightly over the axillary artery.
Despite the low sensitivity and relative inaccuracy of axillary
temperature in detecting fever, this method is recommended by The
American Academy of Pediatrics as a screening test for fever in
newborns.
Tympanic thermometry
In order to obtain a precise temperature reading, good command of
the measurement technique is required. The thermometer probe
must be placed as close as possible to the warmest part of the
external ear canal. An incorrectly placed probe could lead to a false
temperature reading.
NORMAL TEMPERATURES ACCORDING TO MEASUREMENT METHOD
MEASUREMENT METHOD NORMAL TEMP°
RECTAL 97.88°F
ORAL 95.9°F – 99.5°F (35.5°C – 37.5°C)
AXILLARY 94.5 °F – 99.14°F (34.7°C – 37.3°C)
AURICULAR 96.44°F – 100.4°F (35.8°C – 38°C)
TEMPORAL (FeverWatchers) 96.44°F – 100°F (35.8°C – 37.8°C)
The temperature of the human body varies throughout the day. It
can also be influenced by numerous external factors: age, sex, type
and thickness of skin, etc.
