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.
Note: Use of the probe cover may result in a 0.01

(0.02

) discrepancy from actual temperature.

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.

 PRODUCT FUNCTIONS & FEATURES

This product has two parts functions : the first function can be used as a basic thermometer for monitoring 
ovulation cycles and other physiological information, this function should be used by women to measure 
basal body temperature. the second function can be used as a normal thermometer ,used to measure and record
 body temperature data, this function suitable for most people to use .

 

 
HOW TO USE THIS PRODUCT

1.Please download and install APP before using this product. Then register new account use your email account 
   and select your purpose, ovulation monitoring or normal thermometer.
2.Turn on the phone bluetooth through APP and press the on/off button next to LCD display to turn on the device.
    The display will briefly shows full segment at current unit mode with beep tone. Followed by last stored 
    temperature , and shows 37.00

℃ 

or

 

98.60

℉.

Then select the device ID by the APP and bind it. While it 

    connected successful , APP will be synchronized with the thermometer.

*Note: 

      

. If the measured temperature is less than  32

.

00

 or  89

.

60

, the LCD will display “Lo” below 

            the graduation lines without scale bar, if the measured temperature is higher than 43

.

9

9

            or 111.18

, the LCD will display  all scale bars with “Hi” above.

      

②.

When

 

the LCD display “----” , it means that the thermometer is waiting for Bluetooth  connection, you

            only have 30 seconds to connect your thermometer  , otherwise it will skip the Bluetooth connection into 

            the normal temperature  measurement. Or you can press the on/off button to skip the waiting for  Bluetooth

            connection into the normal temperature immediately.

TAKE YOUR TEMPERATURE

PART1: For normal thermometer , 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. Normal temperature between 35.70

 and  37.30

           (96.26

 and 99.14

)

     b)  

Rectal Use:

  Lubricate silver probe tip with petroleum jelly for easy insertion.  Gently insert 

           sensor approximately 1cm (less than 1/2 ") into rectum.  Normal temperature between 36.20

           and 37.70

 (97.16

 and 99.86

).

     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. Normal temperature between 35.20

 and 36.70

         (95.36

 and 98.06

).

PART2: For basal body temperature ,while wake up in the morning ,open the APP and measurement method 

     reference to above Oral Use

WARM TIPS

.  

When the peak temperature has been reached,  the  

 or 

 will stop flashing and the thermometer will sound a series of beeps. 

        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.

.  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.
