Important Safety Information
To assure the correct use of the product basic safety measures should always be followed including the precautions listed
below.
Warning:
• Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
• Conducting self-diagnosis based on the measurement results and/or treatment can be dangerous. Please follow the
instructions of your doctor. Self-diagnosis may worsen the symptoms.
• A high or prolonged fever requires medical attention, especially for small children. Please contact your doctor.
• Please keep still during measurement.
• Do not forcibly insert the probe in the ear.
• If you feel discomfort such as a pain during the measurement, stop using the unit immediately. It may injure the external
auditory canal.
• Do not use this unit if suffering from ear disease such as otitis externa or otitis media. It may worsen the condition.
• Do not use this unit when the external auditory canal is wet such as after swimming or taking a bath. It may injure the
external auditory canal.
• Do not use this unit without attaching a probe cover.
• Please ensure that the ear canal is clean and free of earwax.
• If the probe cover becomes dirty with earwax or other substances, replace it with a new one.
• Do not use a probe cover after someone else has used it. This can lead to cross infections such as otitis externa.
• Correct measurement result may not be obtained if dirty probe covers are used.
• Proper installation of the probe cover ensures accurate measurements.
• When the infrared sensor becomes dirty, wipe it lightly with a soft dry cloth or a cotton swab. Do not wipe the infrared
sensor with tissue paper or a paper towel.
• Do not use more than one probe cover at a time.
• If there is any temperature difference between the places where the unit is stored and where you are going to measure,
leave the unit in the room where you are going to use it for more than 30 minutes to allow it to reach room temperature first,
then measure.
• If the ear is cold, wait until the ear is warmed up before taking a temperature measurement. The measured result may indicate
low when you use an ice bag or an ice pack or immediately after coming in from the outside in winter.
• Do not touch the infrared sensor with a finger or breathe on it.

2
Important Safety Information
• Do not attempt measurements when the unit is wet as inaccurate readings may result.
• Check the symbol on the display before and after the measurement so that the measurement is taken in the appropriate
mode.
• Keep the unit out of children’s reach.
• Avoid children trying to measure themselves or others as they may damage the ear.
• Contains small parts that may cause a choking hazard if swallowed by infants.
• Do not throw batteries into a fire. The battery may explode.
• Remove the battery when the unit 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.
• During measurement, make sure that no mobile phone or any other electrical devices that emit electromagnetic fields is
within 30cm of this device. This may result in incorrect operation of the device and/or cause an inaccurate reading.
General Precautions
• Do not use this unit other than for measuring the temperature in the human ear.
• Do not apply a strong shock to, drop, step on, or vibrate the main unit.
• The main unit is not waterproof. Be careful when handling this unit so that no liquid (alcohol, water, or hot water) will get into
the main unit. When the unit is wet with vapor, wait until it dries or wipe it lightly with a soft dry cloth.
• Do not disassemble, repair, or modify the unit.
• When you inform your doctor of your temperature, make sure you state that you measured the temperature in the ear.

3. Using the Unit
3.1 Taking a Reading
Notes:
• Make sure the probe cover is attached correctly.
• It is recommended that you measure 3 times with the same ear. If the 3 measurements are different, select the
highest temperature.
1. Press the ON/MEM button.
All symbols appear on the display.
Then the display shown at the right will appear with 2 beeps.
2. Insert the probe into the ear as far as it comfortably goes in
the direction of the eardrum.
Notes:
• Gently pull the ear back to straighten the ear canal and position the probe into the ear so
it is snug, aiming towards the membrane of the eardrum to obtain an accurate reading.
• Holding the unit too long may cause a higher ambient temperature reading of the probe.
This could make the body temperature measurement lower than usual.
