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 young 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. Consult with your doctor for the interpretation of results. Self-diagnosis may lead to the worsening of existing disease conditions.
  • This thermometer is used for taking temperatures through oral, rectal or underarm. 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 on the thermometer. Doing so may lead to breakage and/or injury.
  • Do not share the thermometer 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 mobile phones near the thermometer.
  • 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 force the thermometer into the rectum. Stop insertion and abort the measurement when pain is present. Failure to do so may lead to injury.
  • 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.
  • Do not attempt to disinfect the sensing section of the thermometer by immersing in alcohol or in hot water (water over 50°C).
  • Failure to use a probe cover may lead to bacteria and viral infection.

GENERAL SAFETY PRECAUTIONS

  • Do not use the thermometer to measure anything other than human body temperatures.
  • Do not drop the thermometer and protective case or expose them to shock or vibration.
  • Do not store the thermometer in the protective case when it is damp. Wipe it off with a dry cloth first.
  • Avoid taking the temperature until after 30 minutes has lapsed after exercise, bathing or eating/drinking.

SWITCHING BETWEEN FAHRENHEIT/CENTIGRADE (CELSIUS)

Press the POWER button for 7 seconds until a beep is emitted. The display will change to the other measurement scale at the time when the beep sounds.

RECTAL USE:
Always use a probe cover when taking rectal measurements.

  • Commonly used for young children when it is difficult to take an oral or underarm temperature.
  • Lubricate with a water-soluble gel. Do not use petroleum jelly.
  • Gently insert the probe 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.

UNDERARM (AXILLARY) USE:

UNDERARM (AXILLARY) USE
  • Place the probe tip in the center of the armpit.

TAKING THE TEMPERATURE

If possible, a full probe cover covering all sections should be used. Replace the probe cover with a new one after each use. Probe covers are included with the thermometer, place a probe cover carefully over the tip.

TAKING THE TEMPERATURE

1.Press the button.
A default temperature 37.0°C (98.6°F) is shown up on display.
NOTE: When a temperature other than 37.0°C (98.6°F) is displayed, please refer to the
“TROUBLESHOOTING” section for details to correct the problem.

2. Apply the thermometer to the measurement site.
Use the oral, rectal or underarm site for measurement.
NOTE: Even if the “L” indicator fails to display (when only the temperature is displayed), this is not an error. So the temperature may be taken as is.

3. When the reading is ready, the thermometer will emit a () sound three times. Remove the thermometer from the measurement site and read the result.

BUZZER NOTIFICATION TIMING

Oral : approx. 80 seconds
Rectal : approx. 60 seconds
Underarm : approx. 2 minutes

NOTES:

  • The buzzer notification timing is based on an environmental temperature of 23 degrees without the probe cover.
  • There will be individual differences in the measurement results.

4. Turn off the thermometer and store it in the protective case.

NOTES:

  • The reading will automatically be stored in memory.
  • Although the thermometer will automatically switch itself off 30 minutes after use or after 3 minutes when it has not been used; it should be turned off manually to conserve the battery.

DISPLAYING THE LAST TEMPERATURE
Press the POWER button to display the temperature that was measured most recently. For details, please refer to the “TAKING THE TEMPERATURE” section.

CORRECT MEASUREMENT
Measurement accuracy cannot be assured when the method used to measure the temperature is incorrect.
ORAL USE (for ages 4 and older):
The mouth should remain closed up to 5 minutes before attempting 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.
  • Use downward tongue pressure to hold the thermometer in place.
  • Hold the thermometer to keep it from sliding around in the mouth.
