Model:DMT-4760b
Warning :
Read instructions thoroughly before using 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 thermometer in ear. Designed use is for oral, rectal, and armpit (axilla) readings only.
Do not place thermometer battery near extreme heat as it may explode.
Remove 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 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 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 ( ), leave it in
(5℃～40℃) ambient temperature for about 15 minutes before using it.

PLEASE READ CAREFULLY BEFORE USING
The predictive digital thermometer provides a quick and highly accurate reading of an individual's
body temperature. Predictive-read thermometers are quicker than actual read thermometer.
Predictive read type thermometers display the temperature results in a short period of time which
are equivalent to balance temperature after 5 minutes according to the particular algorithm.
Therefore, users only need about 5 seconds to take the temperature readings. Due to measurement
sites of predict thermometer are different, the reading time also may be different, but the actual time
is usually between 5 and 10 seconds. (See below Figture 1)

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 clinical accuracy of the thermometer is in question. Turn on the thermometer
and insert 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
( ) for electronic thermometers is ( ).37.0 to 39.0 °C ±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.
CLEANING AND DISINFECTION
2)Using a clean, soft cloth to wipe the thermometer down to remove any residue;
3)Repeat step 1 and 2 for three times until no soil is seen with visual inspection after cleaning;
4)For thoroughly clean 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 68℉;
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 step 1 to 3 to remove OPA residuals;
Note1: Rectal use is not recommended for home use as OPA will not be readily available outside of a hospital.
If 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 long time.
-Do not use ultrasonic washing to clean the thermometer.
1)Immerse the thermometer probe in distilled water for at least 1 minute;

Bluetooth requirements
1.
2.
The Glucose Meter requires a bluetooth device with:
* Bluetooth 5.0.1 *Android 6.0 or later *IOS 10.0 or later.
And works with: . iphone , iPod, iPad . Android Phones and Tablets.
3. Position thermometer in desired location (mouth, rectum, or armpit.)
a) Oral Mode: Place thermometer under tongue as indicated by
position shown in Figure 7. Close your mouth and breathe evenly
through the nose to prevent the measurement from being influenced
by inhaled/exhaled air.
b) Rectal Mode: Lubricate silver probe tip with petroleum jelly for easy insertion. Gently insert
sensor approximately 1cm (less than 1/2 ") into rectum.
c) Underarm Mode: Wipe armpit dry. Place probe in armpit and keep arm pressed firmly at side.
From a medical viewpoint, this method will always provide inaccurate readings, and should not
be used if precise measurements are required.
d) Bath Mode: It will display Lo and then ℃ or ℉ is still flashing( ), then place
probe tip into bath water.
Note: The accuracy of unit must be tested using water bath in bath mode.
4. The three dashes (---) will flash sequentially throughout the testing process, and at the same time
the “ ” are flashing(See Figure 8).When flashing stops an alarm will beep for approximately 10
seconds. The predictive measured reading will appear on the LCD simultaneously(
℉ see Figure 9).The measurement time of the oral/underarm/rectal mode varies with the
individual, which are between 5 and 10 seconds.
:The minimum measurement time of Bath Mode until the signaling tone (beep) must be
maintained without exception.
5. The thermometer will enter into the Actual Measurement after 3 minutes except Bath Mode,At the
same time you can hear two beeps as a cue ( The “ ” will disappear and the Actual measurement
temperature display see Figure10), users can take the true body temperature at this time. Users can
compare the predictive temperature result with true temperature result. In order to achieve better body
temperature measurement result, recommend to keep the probe in mouth and rectum about 2 minutes,
or in armpit about 5 minutes regardless of the beep sound and at least 30 seconds measurement
intershould be maintained.
6. To prolong battery life, press the On/Off Button to turn unit off after testing is complete. If no action
is taken, the unit will automatically shut off after around10 minutes.
7. Store the thermometer in its protective case.
