FAST-READ 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.
■ Thermometer is water resistant, but not 100% water proof. Do not submerge
unit in any liquid.
■ Convenient memory feature: automatic recall of last temperature reading.
■ Long-life, replaceable battery (approximately 3,000 temperatures).
■ Low Battery Indicator “ ”.
■ Auto-Off in approximately 9 minutes.
■ Oral, rectal or underarm use.
■ Beeps when peak temperature is reached.
HOW TO CARE FOR THIS PRODUCT
■ The thermometer should be cleaned after every use even when probe covers are
used.
■ Clean the thermometer tip and probe using isopropyl alcohol or soap and water.
Do not boil the thermometer. Do not submerge the thermometer in any liquid.
■ 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
considered 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. Firmly push the START button. The thermometer will beep and the display will
show all display symbols. This is a function check indicating the unit is working
properly. If a previous reading is stored in memory, the thermometer will display
the last temperature for two seconds.
3. The °F or °C symbol will flash when the unit is ready to measure temperature.
Begin measurement.
4. When peak temperature is reached, the °F or °C symbol will stop flashing, and
the thermometer will beep eight times.
5. 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.
6. 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 15-25 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
body. The measuring sensor should be pointing upward
parallel to the arm.
■ The time required for an accurate underarm temperature may be 5 minutes or
longer depending on the placement of the probe and closure of the arm against
the body.
