DIGITAL THERMOMETER OWNER S MANUAL
Model: DMT-101

Warning :
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 (axilla) readings only.
Do not place the thermometer battery near extreme heat as it may explode.
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℉～104℉(5℃～40℃), leave it in 41℉～104℉ (5℃～40℃) ambient temperature for about 15 minutes before using it.

DIRECTIONS
1. Press the On/Off Button next to the LCD display. A tone will sound as the screen shows, followed by the last record 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“√” 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.
b) Rectal Use: Lubricate silver probe tip with petroleum jelly for easy insertion. Gently insert sensor approximately 1cm (less than 1/2 “) into the rectum.
c) Armpit Use: Wipe armpit dry. Place the probe in the armpit and keep the 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.
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 alarm beeps more rapidly when the temperature the buzzes are“ Bi-Bi-Bi- B i-”; reaches 100 (37.8 ) or higher, and the ℉ ℃ he buzzes are“ Bi-Bi-Bi—– Bi- Bi-Bi——- 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 around10 minutes.

CLEANING AND DISINFECTION

1. Immerse the thermometer probe in distilled water for at least 1 minute;

2. Using a clean, soft cloth to wipe the thermometer down to remove any residue;

3. Repeat steps 1 and 2 for three times until no soil is seen with visual inspection after cleaning;

4. For thoroughly cleaning and disinfection, please use method A or B：
   Method A(High-level disinfection): immerse the thermometer probe in 0.55% OPA(O-Phthaldehyde), such as CIDEX OPA, for at least 12 minutes under temperature at 20℃;
   Method B(Low-level disinfection): Using a clean soft cloth dipped in 70% medical alcohol, wipe the probe 3 times, at least one minute for each time.

5. Repeat steps 1 to 3 to remove OPA residuals;
   Note 1: Rectal use is not recommended for home use as OPA will not be readily available outside of a hospital.
   If the rectal measurement is necessary, we strongly recommend high-level disinfection.
   Note2 : Please operate according to the manual of OPA for reference.
   To prevent damage to the thermometer please note and observe the following:
   -Do not use benzene, paint thinner, gasoline, or other strong solvents to clean the thermometer.
   -Do not attempt to disinfect the sensing probe (tip) of the thermometer by immersing in alcohol, OPA, or in hot water (water over 122℉(50℃) for a long time.
   -Do not use ultrasonic washing to clean the thermometer.

CALIBRATION
The thermometer is initially calibrated at the time of manufacture. If the thermometer is used according to the use 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.
