  • Read instructions thoroughly before using a digital thermometer.
  • Choking Hazard: Thermometer cap and battery may be fatal if swallowed. Do not allow children to use this device without parental supervision.
  • Do not use a thermometer in-ear. Designed use is for oral, rectal, and armpit (Wits) readings only.
  • Do not place the thermometer battery near extreme heat as it may explode.
  • Note: Use of the probe cover may result in a 0.27(0.1r ) discrepancy from actual temperature.
  • Remove the battery from the device when not in operation for a long time.
  • The use of temperature readings for self-diagnosis is dangerous. Consult your doctor for the interpretation of the results. Self-diagnosis may lead to the worsening of existing disease conditions.
  • Do not attempt measurements when the thermometer is wet as inaccurate readings may result.
  • Do not bite the thermometer. Doing so may lead to breakage and/or injury.
  • Do not attempt to disassemble or repair the thermometer. Doing so may result in inaccurate readings.
  • After each use, disinfect the thermometer especially in case the device is used by more than one person.
  • 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 use a thermometer orally after being used rectally.
  • For children who are two years old or younger, please do not use the devices orally.
  • If the unit has been stored at temperatures over 41°F —1047 or —40t), leave it in 417 —1047 (5410 —40°C) ambient temperature for about 15 minutes before using it.

Temperature readings are available in the Fahrenheit or Celsius scale (Tit; located in the upper right corner of LCD.) With the unit off, press and hold the On/Off Button for approximately 2 seconds to change the current setting.


  1.  Press the On/Off Button next to the LCD display. A tone will sound as the screen shows; BRE, followed by the last recorded temperature. After showing the self-test temperature, the thermometer is now in testing mode.
  2. Position thermometer in the desired location (mouth, rectum, or armpit.)
    a) Oral Use: Place thermometer under tongue as indicated by ” d ” position shown in Figure 2. Close your mouth and breathe evenly through the nose to prevent the measurement from being influenced by inhaled/exhaled air. Normal temperature between 96.37 and 99.17 (35.7 °C and 37.3 °C).
    b) Rectal Use: Lubricate silver probe tip with petroleum jelly for easy insertion. Gently insert sensor approximately lcm (less than 1/2 “) into the rectum. Normal temperature between 97.2°F and 99.97 (36.2 rands 37.7 °C).

    c) Armpit Use: Wipe armpit dry. Place the probe in the armpit and keep arm pressed firmly at the side. From a medical viewpoint, this method will always provide inaccurate readings, and should not be used if precise measurements are required. Normal temperature between 95.4°F and 98.1°F (35.2 °C and 36.7 °C).
  3. The degree sign flashes throughout the testing process. When flashing stops an alarm will beep for approximately 10 seconds. The measured reading will appear on the LCD simultaneously. The minimum measurement time until the signaling tone (beep) must be maintained without exception. The measurement continues even after the buzzer notification. So that in order to achieve better body temperature measurement results, recommend to keep the probe in the mouth and rectum for about 2 minutes, or in the armpit for about 5 minutes regardless of the beep sound and at least 30 seconds measurement interval should be maintained.
    *Note: Normally the buzzes are ” Bi-Bi-Bi- Bi-“; Alarm beeps more rapidly when the temperature reaches 100°F (37.8°C) or higher, and the buzzes are “Ri-Ri-Ri Ri-Ri-Ri Bi-Bi-Bi”
  4. To prolong battery life, press the On/Off Button to turn the unit off after testing is complete. If no action is taken, the unit will automatically shut off after around 10 minutes.


Error message Problem Solution
. I temperature taken is lower than 90.0°F(32.0°C) Turn off, wait one minute and take a new temperature via close contact and sufficient rest.
Temperature taken is higher than 109.9°F(42.9°C) Turn off, wait one minute and take a new temperature via close contact and sufficient rest.

Dead battery: Battery icon is flashing, can’t be measurable. Replace the battery.


  1. Replace the battery when ” ” appears in the lower right corner of the LCD display.
  2. Pull battery cover off as shown in Figure 3.
  3. Gently pull out plastic circuit board with battery chamber approximately 1 cm (slightly less than1/2″.) (See Figure 4)
  4. Use a pointed object such as a pen to remove old batteries. Discard battery lawfully. Replace with new 5V DC button type LR41 or SR41, UCC392, or equivalent. Be sure the battery is installed with  “±”  polarity facing up. (See Figure 5)
  5. Slide the battery chamber back into place and attach the cover.

Wipe the thermometer with a soft clean cloth. For stubborn stains, wipe the thermometer with a cloth that has been dampened with water or a neutral detergent solution and then wring thoroughly. Finish by wiping with a soft dry cloth. For disinfection, 75% Ethanol or Isopropyl alcohol can be used. Observe the following to prevent damage to the thermometer. -Do not use benzene, thinner, gasoline, or other strong solvents to clean the thermometer. -Do not attempt to disinfect the sensing section (tip) of the thermometer by immersing in alcohol or in hot water (water over 122°F (50 °C)). -Do not use ultrasonic washing to clean the thermometer.
The thermometer is initially calibrated at the time of manufacture. If the thermometer is used according to the user’s instruction, periodic readjustment is not required. However, we recommend checking calibration every two years or whenever the clinical accuracy of the thermometer is in question. Turn on the thermometer and insert it into the water bath and then check the laboratory accuracy. Please send the complete device to the dealers or manufacturer. ASTM laboratory accuracy requirements in the display range of 98.6 to 102.2 °F (37.0 to 39.0 °C) for electronic thermometers is ±0.2°F(±0.1 °C). The above recommendations do not supersede the legal requirements. The user must always comply with legal requirements for the control of the measurement, functionality, and accuracy of the device which are required by the scope of relevant laws, directives, or ordinances where the device is used.
Caution: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user authority to operate the equipment. *Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
