DIGITAL THERMOMETER
SAFETY INFORMATION
■ 
High, prolonged fever requires medical attention (over 100.0°F or 37.8°C) for 
young
 children. In case of high readings, please contact your physician.
■ 
Do not allow children to take their temperature unattended.
■ 
Read the enclosed instructions carefully to ensure accurate temperature readings. 
Temperature readings are affected by many factors including exercise, drinking 
hot
 or cold beverages prior to taking, and technique.
■ 
Do not allow children to walk or run during temperature taking. The rigid probe 
could
 present a hazard.
■  Oral, underarm, and rectal temperatures vary by approximately 1°F (0.5°C).
SPECIAL PRODUCT FEATURES
■ 
Reads temperature in Fahrenheit or Celsius.
■ 
Memory feature: automatic recall of last temperature reading.
■ 
Beeps when peak temperature is reached.
■ 
Auto-Off in approximately 9 minutes.
■ 
Thermometer is water resistant, but not 100% waterproof. Do not submerge unit 
in
 any liquid.
■ 
Long-life, replaceable battery (approximately 3,000 temperatures).
■

HOW TO CARE FOR THIS PRODUCT
■ 
The thermometer should be cleaned after every use even when probe covers are 
used.

■  Store the unit in the protective case while not in use.
■  Do not store or keep in direct sunlight, or in high temperatures.
■  Do not open the thermometer except to replace the battery.
■  Do not drop the thermometer, as this may break the unit.
■  Do not attempt to disassemble the unit except to replace the battery.
WHAT IS A “NORMAL” TEMPERATURE? 
Temperature readings vary among individuals. A normal temperature refers to each 
individual
’s average temperature while they are well. Normal average temperatures 
range
 from 97°F/36.1°C to 100°F/37.7°C when taken orally. A rectal temperature is 
conside
red your real or “core” body temperature. A rectal temperature is 1°F/0.5°C 
higher
 than an oral reading and an underarm temperature is 1°F/0.5°C lower than 
an
 oral reading.
HOW TO TAKE TEMPERATURE
1.  Select oral, underarm or rectal as your measurement site (see following instruc-
tions).
2.  Push the START button located at the top of the thermometer. The thermometer 
will
 beep and the display will show all symbols.. This is a function check indi
-
cating
 the unit is working properly. If a previous reading is stored in memory, 
the
 thermometer will display the last temperature for two seconds. The flashing 
symbol
 °F (or °C) will appear with the “L” or “H” symbol indicating that the 
thermometer
 is ready for measurement. Begin measurement.
3.  When the °F (or °C) symbol stops flashing and the thermometer emits eight 
beeps,
 the temperature measurement is complete.
4. Read and record the temperature and time for reference. The reading will auto-
matically
 be stored in the memory until another reading is taken or the batteries 
are removed from the thermometer.
5. Push the START button to turn the unit off. If you do not turn the unit off, it will 
shut
 off automatically in approximately 9 minutes.
NOTE: If the measured temperature is higher than 99.5°F (37.5°C), the fever alarm 
will beep quickly for about four seconds.
ORAL USE
■ 
Do not drink hot or cold fluids, exercise, smoke or 
perform
 other activities that raise or lower temperature. 
The
 mouth should remain closed up to 5 minutes before 
attempting
 a reading.
■ 
Place the probe tip well under the tongue in locations as 
indicated
 by the “
✓ 
” (see diagram). Instruct children 
not to
 bite down on the probe.
■ 
The approximate measurement time is 60 seconds. 
Opening
 the mouth or improper placement of the probe 
tip
 may result in a longer time for a reading.
UNDERARM (AUXILIARY) USE
■ 
From a medical point of view, this method will always 
give
 an inaccurate reading and should not be used if a 
precise measurement is required.
■ 
Wipe underarm with a dry towel.
■ 
Place probe tip in armpit and bring arm down against the 
bod
y. The measuring sensor should be pointing upward 
parallel
 to the arm.
■ 
The approximate measurement time may be 5 minutes or longer depending on 
the
 placement of the probe and closure of the arm against the body.
