Model:DMT-4318
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.The Patient is an intended operator.
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 41℉～104℉(5℃～40℃), leave it in 41℉～104℉
(5℃～40℃) ambient temperature for about 15 minutes before using it.

2. Position thermometer in 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 rectum.
c) Armpit Use: 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.
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 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 interval
should be maintained.
4. 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.
*Note: Normally Alarm b eeps m ore ra pidly w hen te mperature the buzzes are“ Bi-Bi-Bi- B i-”;
reaches 100 (37.8 ) or higher ,and t℉ ℃ he buzzes are“ Bi-Bi-Bi----- Bi-Bi-Bi------- Bi-Bi-Bi”
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 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 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 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.
