INTRODUCTION

Thank you for choosing the TD-1242 Forehead Thermometer. Please read this instruction manual first so you can use this thermometer safely and correctly. Please keep this instruction manual for future reference. This innovative medical device uses advanced infrared (IR) technology to measure temperature instantly and accurately on the forehead/surface. The TD-1242 Forehead Thermometer delivers a body temperature reading from the thermal radiation emitted from the forehead without contact with the body. (The surface temperature measurement is not for medical purposes.) Before using this product, please read the following contents thoroughly and carefully.
INTENDED USE
The TD-1242 forehead thermometer is intended for the intermittent measurement and monitoring of human body temperature from the forehead. The device is intended for use of all ages for home and professional use by one with a good understanding of the operation instruction, where the patient may be an operator.
HOW DOES IT WORK
The thermometer measures the infrared heat generated by the surface of the skin over the vessel and its surrounding tissue. The thermometer then converts it into a temperature value shown on LCD.

IMPORTANT SAFETY INSTRUCTIONS

READ THIS BEFORE USING AND KEEP THESE INSTRUCTIONS

1. Close supervision is necessary when the thermometer is used by, on, or near children, handicapped persons, or invalids.

2. Use the thermometer only for the intended use described in this manual.

3. Do not use the thermometer if it is not working properly, or if it has
   sustained any damage.

4. Keep the sensor end clean and free of debris. See Maintenance section for
   instructions.

5. Do not use ethylene oxide gas, heat, autoclave, or any other harsh methods to sterilize the device.

6. If coming from an environment of warmer or cooler temperature or after a period of exertion, allow the user and the thermometer to acclimate to room temperature for 20 minutes prior to taking a measurement.

7. As the forehead temperature may be affected by sweat, oil, and the surrounding temperature, the reading shall be taken as a reference only.

8. Do not use in presence of flammable anesthetic mixtures.

9. Do not use accessories that are not supplied or recommended by the manufacturer. Do not try to modify the device to prevent any dangers.

10. Proper maintenance is essential to the longevity of your device. If you are concerned about the accuracy of measurement, please contact the local customer service or place of purchase for help.

11. Always contact the manufacturer or the manufacturer’s representative to report unexpected operations or events. Do not try to fix it by yourself.

12. When using the thermometer, stay away from electromagnetic radiation, such as the mobile in use.

13. Do not expose the device to strong electrostatic fields or strong magnetic fields to avoid affecting the measurement accuracy.

14. Used in close proximity to others, EMC must be tested and verified.

15. The small parts detached from the device may result in children choking from inhaling or swallowing.

16. Do not try to maintain the device while it is in use.

17. This thermometer has been calibrated at the factory. If you follow the instructions, you don’t need to adjust them regularly. But if you are in doubt about the accuracy of the readings, please contact customer service.

CAUTIONS AND WARNINGS

MEASURING TEMPERATURES-GENERALS

(older than 36 months)

1. The forehead should be clear of hair and perspiration.

2. Aim at the center forehead area 3 to 7cm (1″ to 2.5″) away from the skin surface. Be sure the thermometer is perpendicular to the skin surface.
   

3. Press and release the SCAN button to take a measurement. A double “beep” sound indicates a reading has been taken and displayed on the LCD screen. When a reading is greater than 38.0°C, a warning symbol will flash with Red backlight.
   

4. To take another measurement, follow steps 2 and 3.

5. The thermometer turns off automatically after 30 seconds.

HINTS ON TAKING TEMPERATURES

1. As with other thermometers, you may observe slight variations in consecutive measurements. It is recommended that you take 3 temperature readings and use the highest one for the following situations:
   • Infants are younger than 3 months old.
   • Children younger than 3 years old and who have a compromised immune system and the presence/absence of fever is critical.
   • When you are learning to use the thermometer.

2. Do not take a reading while the person is moving and/or talking. Wait 30 minutes after any of the following situations before taking a measurement:
   • When the forehead has been covered.
   • After the person has been exercising, swimming, or taking a bath.
   • When the person has been exposed to extreme temperature.

RECALLING PAST READINGS

The TD-1242 stores 30 most recent readings.

1. Press and release the SCAN button to turn on the thermometer.

2. Press and hold the MEMORY button for 1 second to enter the memory
   mode indicated by a flashing “ ” symbol. The most recent reading stored will be displayed.
   

3. Press and release the MEMORY button to cycle through older readings. 4. When left idle for 30 seconds, the thermometer automatically switches off.

NOTE:
When the memory is full, the oldest result is deleted as the new ones are added. While recalling previous readings, you may take a measurement by pressing the SCAN button.

NORMAL BODY TEMPERATURE & FEVER

Body temperature can vary from one individual/person to the next. It also varies by location on the body and time of day. Fever indicates that the body temperature is higher than normal. This symptom may be caused by infection, overdressing, or immunization. Some people may not experience fever even when they are ill. These include, but are not limited to, infants younger than 3 months old, persons with compromised immune systems, persons taking antibiotics, steroids, or antipyretics (aspirin, ibuprofen, acetaminophen), or persons with certain chronic illnesses.

Body Site Normal Temperature Range

Oral| 0.6°C (1°F) or more above or below 37°C (98.6°F)
Rectal / Ear| 0.3°C to 0.6°C (0.5°F to 1°F) higher than an oral temperature
Axillary (armpit)| 0.3°C to 0.6°C (0.5°F to 1°F) lower than an oral temperature

Please consult your physician if you are concerned about your body temperature readings.

MAINTENANCE

• The TD-1242 has no user-serviceable internal parts except battery replacement.

• Store in a dry location free of dust and away from direct sunlight.

• Use a soft dry cloth to clean the plastic housing or a cloth dampened with a
  solution of water and mild detergent. Occasionally, 70% isopropanol solution may be used. Never submerge in liquid.

• The sensor window is recessed to assist in keeping it clean and free of debris. Inspect the lens and remove any debris. Smudges may be cleaned by gently wiping the window with a small foam-tipped swab (non-lining) moistened with 70% alcohol. Wait 10 minutes prior to taking temperatures.
