Important Safety Notes

To assure the correct use of the product basic safety, measures should always be followed including the precautions listed below. The patient is an intended operator, and all the functions can be safely used.

WARNING

• A high or prolonged fever requires medical attention, especially for children. Please contact your doctor.
• Carefully read and follow the enclosed instructions to ensure accurate temperature readings.
• Please keep still during measurement.
• 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 reach them. Children may swallow them. If a child accidentally swallows the battery, battery cover or probe cover, please contact a doctor immediately.
• Do not attempt measurements when the thermometer is wet as inaccurate readings may result.
• Please dispose of waste in accordance with national regulations on environmental protection.
• If the product will not be used for a long time, please remove the battery and place it properly.
• When ambient temperature is 40, The time from minimum storage temperature to use is at least 1 hour; The time from maximum storage temperature is at least 2 hour.

CAUTION

• Do not bite 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.
• 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 probe sensor 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

• The ME EQUIPMENT or ME SYSTEM is suitable for home healthcare environments.
• Don’t near active HF surgical equipment and the RF shielded room of an ME system for magnetic resonance imaging, where the intensity of EM disturbances is high.
• Do not use the thermometer to measure anything other than human body temperatures.
• Avoid taking the temperature until after 30 minutes has lapsed after exercise, bathing or eating/drinking.
• Dispose of the thermometer when its service life is reached. Follow local regulations regarding the disposal of such product.
• When the performance changes (such as: inaccurate temperature measurement, inaccurate temperature measurement or abnormal display), please stop using it immediately and contact the after-sales service personnel in time.
• Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of the this device, including cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment could result.

Symbol Definition

Intended use
The Digital Thermometer is designed as reusable battery-operated electronic device, and intended for the measurement of oral, armpit and rectal temperature for people of all ages.

Contraindication
It is forbidden for patients allergic to stainless steel and PC plastic.

How to Use

1. Press the measure but ton to turn on the thermometer (with a short beep). Three color backlight will be displayed, and displays for 1 second, and then shows the last temperature value
   for about 3 seconds（it will not be displayed if it’s for the first time use ）, and then ” —- ” displays. Now you c an start the measure.

2. Place the thermometer in an appropriate position, oral, underarm or rectal.

3. The measurement takes about 10 seconds, after five times beeps, you can remove the thermometer from the site, and take the reading.

NOTES :

1. T indicates a temperature reading:
   • 32℃≤T≤37.3℃(89.6℉≤T≤99.14℉):There will be 5 beeps and displayed in green.
   • 37.3℃<T≤38.7℃(99.14℉<T≤101.66℉):There will be 5 beeps and displayed in orange, which is a warning that you may have a low fever.
   • 38.7℃<T≤42.9℃(101.66<T≤109.22℉):There will be 5 beeps and displayed in red, which is a warning that you may have a high fever.

NOTES:

• To clean the probe before and after using the thermometer to ensure an accurate reading and avoid cross contamination approximately.
• If the temperature is lower than 32℃, it will be displayed in —- .
• If the temperature is higher than 42.9℃，it will be displayed in H1.

Correct Measurement

Measurement accuracy cannot be assured when the method used to measure the temperature is incorrect.

ORAL USE:

The mouth should remain closed till hearing the beeps 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.

NOTE: The Do not drink hot or cold fluids, exercise, and smoke or perform other activities prior to a reading. These activities will raise or lower temperature readings when compared to  your normal, average temperature.

RECTAL USE:

• 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 1.3cm into the rectum. Do not force the tip into the rectum if resistance is encountered.
• Disinfect the thermometer after use.

UNDERARM (AXILLARY) USE:

• Place the probe tip in the center of the armpit.
• Lock the probe tip under the arm, using the arm t o slightly apply pressure inwards.
• In the case of infants and very young children, gently hold the arm to prevent movement.

Body temperature can vary from 97.0℉to 100℉and still be considered normal. The medically accepted‘ normal’ body temperature is 98.6℉. Body temperature is commonly lower in the upon waking than at any point during the rest of individual’s waking hours. Temperature readings will vary based on the body location point of the reading. Oral temperature readings between 97℉(36.1℃) are considered normal. A rectal temperature reading is generally 1℉(0.5℃) higher; while an underarm, or axillary, temperature will be 1℉(0.5℃) lower. The common normal temperature and fever temperature in different locations of the human body are shown in the following table.

NOTE: A fever is defined as body temperature that is elevated above the normal for that person. It is important to determine what is normal for an individual before determining if a fever is  present. Tracking an individual’s temperature on a consistent basis, at the same body site and at the same time every day when the person is well or healthy will help determine an individual’s normal temperature.

℃ /℉ Switchable
When the thermometer is turned on with a display of “- – – -“, press and hold the M But ton for 1 second to switch the temperature unit.

Memory Recall
When the thermometer is turned off, press the M but ton to check the previous data one by one.

Battery Replacement

When the symbol ” charging “flashes, the battery needs to be replaced.

1. Use a coin to take off the battery cover.
2. Remove the battery
3. Insert the new battery with the“ +” pole facing up as shown in the diagram.
4. Use a coin to put the battery cover back.
