Warning :
Read instructions th oroughly before using digital thermome ter.
Choking Hazard: Thermometer cap and batt ery may be fatal if s wallowed. Do not allow children
to use this device witho ut parental supervision.
Do not use thermometer i n ear. Designed us e is for oral, rectal, and armpit (axilla) readings only.
Do not place thermomet er battery near extreme heat as it may explode.
Note: Use of the probe cov er may result in a 0.01℃(0.02℉) discrepancy from actual t emperature.
Remove battery from th e device when not in operation for a long time.
The use of temperature r eadings for self-diagnosis is dangerou s. Consult your doctor for the
interpretation of re sults. Self-diagnosis may lead to the wors ening of existi ng disease conditions.
Do not attempt measure ments when the th ermometer is wet as inaccurate readings may result.
Do not bite the thermome ter. Doing so may lead to breakage an d/or injury.
Do not attempt to disass emble or repair t he thermometer. Doing so may resu lt in inaccurate readings.
After each use, disinf ect the thermom eter especially in case the device is used by more than one perso n.
Do not force the thermom eter into the rec tum. Stop insertion and abort the measurement when pain is
present. Failure to do s o may lead to injur y.
Do not use thermometer o rally after bei ng used rectally.
For children who are two y ears old or younger, please do not use the devices orally.
If the unit has been store d at temperatur es over 5℃ ～40℃(41℉ ～104℉), leave it in 5℃～40℃

PRODUCT FUNCTIONS & FEATURES
This product has two par ts functions : the first function can be used as a basic thermome ter for monitoring
ovulation cycles and o ther physiological information, this function shoul d be used by women to measure
basal body temperatu re. the second function can be used as a normal thermometer ,us ed to measure and record
body temperature dat a, this function suitable for most people to use .
HOW TO USE THIS PRODUCT
1.Please download an d install APP be fore using this product. Then regis ter new account use your email account
and select your purpos e, ovulation monitoring or normal thermo meter.
2.Turn on the phone bl uetooth through APP and press the on /off button next to LC D display to turn on the device.
The display will briefly shows full segmen t at current unit mode with beep tone. Followe d by last stored
temperature , and show s 37.00℃ or 98.60℉. Then selec t the device ID by the APP and bind it. While it
connected successf ul , APP will be synchronized with the t hermometer.
*Note:
①. If the measured temper ature is less than 32.00℃ or 89.60℉, the LCD will displ ay “Lo” below
the graduation lines w ithout scale bar, if the measured temperature is higher t han 43.99℃
or 111.18℉, the LCD wi ll display all scale bars with “Hi” above.
②.When the LCD display “ ----” , it means that the thermometer is waiti ng for Bluetoot h connection, you
only have 30 seconds to co nnect your thermometer , otherwise it will s kip the Bluetooth connection into
the normal temperatu re measurement. Or you can press the on/off button to skip the waiti ng for Bluetoot h
connection into the no rmal temperature immediately.
TAKE YOUR TEMPERATURE
PART1: For normal thermom eter , position t hermometer in desired location (mouth, r ectum, or armpit.)
a) Oral U se: Place therm ometer under tongue as indicated by“√ ”
position shown in Figu re 2. Close your mouth and breathe evenly
through the nose to prev ent the measurement from being influence d
by inhaled/exhaled a ir. Normal tempe rature betwee n 35.70℃ and 37.30℃
(96.26℉ and 99.14℉)
b) Rect al Use: Lubrica te silver probe tip with petroleum jelly for e asy insertion . Gently insert
sensor approximate ly 1cm (less than 1/2 ") into rectum. Normal tem perature betw een 36.20℃
and 37.70℃ (97.16℉ and 99. 86℉).
c) Armp it Use: Wipe armpit dry. Place pro be in armpit and ke ep arm pressed firmly at side.
From a medical viewpoi nt, this method will always provide inaccu rate readings , and should not
be used if precise measu rements are required. Normal temperatu re between 35.2 0℃ and 36.70℃
(95.36℉ and 98.06℉).
PART2: For basal body tempe rature ,while w ake up in the morning ,open the APP and measurement method
reference to above Ora l Use
WARM TIPS
①. When the peak t emp erature has been reach ed, t he ℃ or ℉ will stop flash ing a nd the thermomete r wil l sound a series of beeps.
The mini mum measurement time u nti l the signaling ton e (be ep) must be maintai ned w ithout exception. The measuremen t
continues e ven a fter the buzzer notifi cat ion. So that in order t o ach ieve better body te mpe rature measurement r esult,
recommend t o kee p the probe in mouth and rec tum a bout 2 minutes, or in a rmp it about 5 minutes re gar dless of the beep sound
and at least 30 s eco nds measurement inte rva l should be maintai ned .
②. To prolong battery life , pre ss the On/Off Butto n to tu rn unit off afte r testing is complete. I f no ac tion is taken, the un it wi ll
automatic all y shut off after a rou nd10 minutes.

-Do not attempt to disinfect the sensing section (tip) of the thermometer by immersing in
alcohol or in hot water (water over 50℃(122℉)).
-Do not use ultrasonic washing to clean the thermometer.
CALIBRATION
The thermometer is ini tially calibrated at the time of manufacture. If the thermo meter is used acc ording to
the use instruction, p eriodic readjustment is not required. Ho wever, we rec ommend checki ng calibration
every two years or whene ver clinical accuracy of the thermometer is in question. Tur n on the thermome ter
and insert into the wate r bath and then check the laboratory accuracy of thermomete r. Please send the
complete device to the d ealers or manufacturer.
The above recommenda tions do not supersede the legal requireme nts. The user must always comply with
legal requirements f or the control of the measurement, functio nality, and accurac y of the device whi ch
are required by the scop e of relevant laws, directives or ordinanc es where the devi ce is used.
