Introduction
Thank you for purchasing the OMRON Digital
Thermometer Eco Temp Basic.
The thermometer you purchased offers a safe,
accurate and quick temperature reading. You
can measure your temperature either in the
anus (rectally), in the mouth (orally) or in the
armpit (axillary). This thermometer eliminates
any worries about broken glass or mercury
hazards. Note that your temperature is
affected by smoking, eating or drinking.
Contact your doctor if you have any questions
regarding specific temperatures.
Important Safety Notes
To assure the correct use of the product basic
safety measures should always be followed
including the precautions listed below.
Warning
• A high or prolonged fever requires medical
attention, especially for small children.
Please contact your doctor.
• Carefully read and follow the enclosed
instructions to ensure accurate temperature
readings. Note that temperature readings are
affected by many factors including physical
exertion, the drinking of hot or cold
beverages before measurement, as well as
measuring technique.
• Please keep still during measurement.
• The use of temperature readings for self-
diagnosis is dangerous and may lead to the
worsening of the existing conditions. Consult
your doctor for the interpretation of the
results.
• This thermom eter is used for taking
temperatures through oral, rectal or armpit.
Do not attempt to take temperatures at other
sites, such as in the ear, as it may result in
false readings and may lead to injury.
• Store the thermometer out of the reach of
children. Do not allow children to take their
temperatures unattended. Children may
injure themselves when attempting to take
temperatures without supervision.
• Do not leave the battery, battery cover or
probe cover where children can get to them.
Children may swallow them. Should a child
swallow the battery, battery cover or probe
cover, contact a doctor immediately.
• Do not attempt measurements when the
thermometer is wet as inaccurate readings
may result.
Caution
• Do not bite down on the thermometer. Doing
so may lead to breakage and/or injury.
• Do not allow the thermometer to be shared
among individuals.
• Do not attempt to disassemble or repair the
thermometer. Doing so may result in
inaccurate readings.
• Do not attempt to incinerate the battery. It
may burst.
• Pay attention to polarity (+ –) when replacing
the battery. Failure to do so may lead to fluid
leakage, heat generation or bursting,
resulting in damage to the unit.
• Remove the battery when the thermometer
will not be used for 3 months or more. Failure
to do so may lead to fluid leakage, heat
generation or bursting, resulting in damage
to the unit.
• Do not use the thermometer in places where
strong static electricity or electromagnetic
fields are present. Doing so may lead to
inaccurate readings and may contribute to
instrument failure.
• Do not attempt rectal measurements on
persons with rectal disorders. Doing so may
aggravate or worsen the disorder.
• Do not step on the unit or the hard case.
General safety precautions
• Do not use the thermometer to measure
anything other than human body
temperatures.
• Do not drop the thermometer and storage
case or expose them to shock or vibration.
1. Switching between Fahrenheit/
Centigrade (Celsius)
Press the button for 7 seconds until a
beep is emitted.
The display will change to the other
measurement system at the time when the
beep sounds.
(Fig. 1, 2, 3)
2. Use of t he thermometer
1. Press the button. (Fig. 4)
The result of the previous measurement is
displayed for a few seconds. Then
37.0°C (98.6°F) is displayed as an internal
test-function. (Fig. 5)
Note: When a temperature other than
37.0°C (98.6°F) is displayed, please refer
to the “6. Display Indications and
Troubleshooting” section for details to
correct the problem.
2. Apply the thermometer to the measurement
site.
Note: Even if the “L” indicator fails to
display (when only the temperature is
displayed), this is not an error. The
temperature may be taken as is. (Fig. 6)
3. The Buzzer notification will emit a [beep-
beep-beep] sound three times to reflect the
earliest temperature indication. Remove the
thermometer from the measurement site
and read the result.
(Fig. 7)
Buzzer notification timing
Rectal: approx. 60 seconds
Oral: approx. 80 seconds
Armpit: approx. 2 minutes*
* 2 minutes is the earliest estimated
temperature indication. To complete the
measurement, it is required to measure
the temperature in the armpit between 5-
10 minutes (depending on the ambient
temperature and condition).
Notes:
• The measurement continues even after
the buzzer notification.
• The buzzer notification timing is based on
an environmental temperature of
23 degrees.
• Since oral and armpit may give lower
measurement results it is recommended
to apply the device rectally to get the most
accurate result.
4. Turn off the thermometer. Clean and
disinfect before returning it to its protective
case.
Notes:
• The reading will automatically be stored in
memory.
• Turn off the thermometer manually to
conserve the battery. It will automatically
switch off 30 minutes after use or
3 minutes when turned on but not used.
3. Displaying the last temperature
Press the button to display the
temperature that was measured most recently.
For details, please refer to the “2. Use of the
thermometer” section.
4. Correct measurement
Measurement accuracy cannot be assured
when the method used to measure the
temperature is incorrect.
Rectal use:
• Commonly used for small children when it is
difficult to take an oral or armpit temperature.
• Lubricate with non-irritating skin-friendly gel.
• Gently insert the pr obe tip no more than
1.3 cm into the rectum. Do not force the tip
into the rectum if resistance is encountered.
• Disinfect the thermometer after use.
Oral use (for ages 4 and older):
The mouth should remain closed up to
5 minutes before starting a reading.
• Place the thermometer in the mouth under
the tongue so that it rests to the left or right of
the root of the tongue. (Fig. 8)
• Use downward tongue pressure to hold the
thermometer in place.
• Hold the thermometer to keep it from sliding
around in the mouth. (Fig. 9)
Armpit (axillary) use:
• Place the sensor tip in the centre of the
armpit. (Fig. 10)
• Lock the sensor tip under the arm, using the
arm to slightly apply pressure inwards.
(Fig. 11)
The following may result in incorrect
measurements:
• Taking the temperature immediately after
exercising, bathing, eating or drinking will
result in an incorrect measurement.
Correct: Wait at least 30 minutes before
taking the temperature.
• Taking the temperature after moving around.
Correct: Take the temperature immediately
after waking up or wait for at least 30 minutes
after moving around.
* Moving around after awakening increases
the body temperature.
The following may result in incorrect
measurements when taking armpit
temperatures:
• Heavy armpit perspiration
Correct: Wipe off any armpit perspiration
before taking the temperature.
• Taking the temperature after being under the
blankets for a long time.
5. Battery replacement
Battery: Alkaline-Manganese Button Battery
LR41 (available commercially)
Battery Replacement Indicator ( )
Replace the batter y when the battery
replacement indicator appears when the
thermometer is switched on.
1. Use a coin to take off the cover. (Fig. 12)
2. Remove the battery. (Fig. 13)
3. Insert the new battery with the “+” pole
facing up as shown in the diagram. Make
sure the battery is put in with the right
polarity.
(Fig. 14)
4. Use a coin to replace the battery cover.
(Fig. 15)
Notes:
• The thermometer comes fitted with a
battery for testing purposes. This battery
may not provide the same amount of
battery life as a new battery.
• Do not loose the O-ring around the screw.
Water-resistant will fail and can lead to
misreadings and failure of the unit.
6. Display Indications and Troubleshooting
7. Storage
Store the thermometer in its storage case.
• Do not store the thermometer in the following types of places. Doing so may damage the
thermometer.
- Wet locations.
- Locations with high heat and humidity or those that are exposed to direct sunlight. Areas
close to heating equipment, dusty locations, or environments where there are high salt
concentrations in the air.
- Locations where the unit will be subjected to leaning, shock or vibration.
- Pharmaceutical storage areas or locations where corrosive gases are present.
8. Cleaning and Disinfecting
OMRON recommends to wipe the device with damp cloth. For disinfection, 70% Ethanol or
Isopropyl alcohol can be used. Do not attempt to disinfect the sensing section of the
thermometer by immersing in alcohol or in hot water (water over 50°C).
Do not submerge deeper than 15 cm and longer than 30 minutes.

Displayed when the surrounding
temperature exceeds 32°C (89.6°F).
[37.0°C (98.6°F)] is
not displayed during
the measurement
preparation period
as a test display,
after the most
recent
