INSTANT FLEXIBLE
DIGITAL THERMOMETER
QUICK START GUIDE
*Read instructions carefully before using the Digital Thermometer.
This digital thermometer provides a quick and highly
accurate reading of an individual's body
temperature. The digital thermometer is intended to
measure the human body’s temperature in regular
mode orally, rectally or under the arm, and the
device is reusable for clinical or home use on people
of all ages. To better understand its functions and to
provide years of dependable results, please read all
instructions first.
DIRECTIONS
1. Press the On/Off Button next to LCD
display. A tone will sound as the screen
shows, followed by last recorded
temperature. After showing the self-test
temperature, the thermometer is now in
the testing mode.
2. Position the 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 96.3oF and
99.1oF (35.7oC and 37.3oC).
b. Rectal Use: Lubricate silver probe tip
with petroleum jelly for easy insertion.
Gently insert sensor approximately 1 cm
(less than ½”) into rectum. Normal
temperature between 97.2oF and 99.9oF
(36.2oC and 37.7oC).
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
95.4oF and 98.1oF (35.2oC and 36.7oC).
3. The degree sign flashes throughout the
testing process. When flashing stops, an
alarm will beep approximately 10
seconds. The measured reading will
appear on the LCD simultaneously. The
minimum measurement time until the
signal tone (beep) must be maintained
without exception. The measurement
continues even after the buzzing
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 around
10 minutes.
WARNING
Choking Hazard:
Thermometer cap may be fatal when swallowed. Do
not allow children to use this device without parental
supervision.
Do not use thermometer in ear. Designed for use in
oral, rectal and armpit (axilla) readings only.
Do not place thermometer near extreme heat, it may
explode.
Use of the Probe Cover may result in a 0.2oF (0.1oC)
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
interpretations of the results. Self-diagnosis may
lead to the worsening of the existing disease
conditions.
Do not attempt to get 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.
CLEANING & DISINFECTION
Wipe the thermometer with a soft clean cloth. For
stubborn stains, wipe the thermometer with a cloth
that has been dampened in water or in neutral
detergent solution and then wring thoroughly. Finish
by wiping with a soft dry cloth. For disinfection, 75%
Ethanol or Isopropyl alcohol can be used. Observe
the following to prevent damage to the
thermometer:
Do not use benzene, thinner, gasoline or
other strong solvents to clean the
thermometer.
Do not attempt to disinfect the sensing
section (tip) of the thermometer by
immersing in alcohol or in hot water
(water over 122oF/50oC).
Do not use ultrasonic washing to clean
the thermometer.

90.0°F(32.0°C)
Warm the tip of the
thermometer and it should
show you a reading if the
temperature is above 900F
(320C).

Turn off, wait one minute and
take a new temperature via
close contact and sufficient
rest.

Replace the battery.
How To Calibrate Your Thermometer:
The thermometer is initially calibrated at the time of
manufacturing. If the thermometer is used according
to the manual, periodic readjustment is not required.
However, we recommend conducting a quick
calibration to confirm that your unit didn't get
damaged during shipment. A quick way to calibrate
your unit is by doing the water test. Dip the tip of the
thermometer into a cup of hot water. Wait for your
thermometer to show 'Hi' or a high temperature
reading number on its LCD display (for example it
shows 38 °C or 100 °F). Then let it sit for a minute or
two then dip it into a cup of cold water. Your display
should show 'Lo' (meaning low temperature not low
battery) or a low temperature reading number this
time (for example it shows 33 °C or 91°F). Leave it at
room temperature for 30 minutes and try using it
again, and if it does not show ‘Hi’ or ‘Lo’ it will mean
you have successfully checked your thermometer
and good to go! If you find that your reading is very
low and/or not changing on the LCD display at all,
please get in touch with us through email with your
Amazon Order ID.
oF/oC SWITCHABLE
Temperature readings are available in the
Fahrenheit or Celsius scale (oF/oC; located in the
upper right corner of LCD). With the unit off, press
and hold On/Off Button for approximately 2 seconds
to change the current setting.
BATTERY REPLACEMENT
1. Replace battery when appears in the
lower right corner of LCD display.
2. Pull battery cover off as shown in Figure
3.
3. Gently pull out plastic circuit board with
battery chamber approximately 1 cm
(slightly less than ½”.) (See Figure 4)
4. Use pointed object such as a pen to
remove old battery. Discard battery
lawfully. Replace with new 1.5 V DC
button type LR41 or SR41, UCC392, or
equivalent. Be sure battery is installed
with
“+” polarity facing up. (See Figure 5)
5. Slide battery chamber back into place
