INDICATIONS FOR USE

The 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. 

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. 

This could present a choking hazard.

☞ 

Oral, underarm, and rectal temperatures vary by approximately 

1°F (0.5°C).

HOW TO CARE FOR THIS PRODUCT

  

The thermometer should be cleaned after every use even when 

probe covers are used.

soap and water.

 

Do not boil the thermometer. 

 

Store the unit in the protective case while not in use.

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 instructions).

2.  Push the ON/OFF button. The thermometer will beep and the 

display will show all 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. The thermometer is ready for measurement. Begin 

measurement.

3.  When the °F/°C symbol stops flashing and the thermometer will 

beep for approximately 10 seconds indicating the temperature 

measurement is complete.

4.  Read and record the temperature and time for reference. The 

reading will automatically be stored in the memory until another 

reading is taken or the batteries are removed from the thermometer.

5.  Push the ON/OFF button to turn the unit off. If you do not turn the 

unit off, it will shut off automatically in approximately 10 minutes.

NOTE: 

If measured temperature is less than 90° F (32.2° C), the LCD will display “Lo”.   
If higher than 109.9° F (42.9° C), “Hi” will be displayed.

ORAL USE

  

Do not drink hot or cold fluids, exercise, 

smoke or perform other activities that raise or 

lower temperature directly prior to taking 

reading.

  

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 10 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 approximate measurement time may be 20 seconds or longer 

depending on the placement of the probe and closure of the arm 

against the body.

RECTAL USE

 

 Commonly used for babies, young children or when it is difficult to 

take an oral or underarm temperature.

  After placing the probe cover on the thermometer, lubricate with a 

water-soluble jelly such as K-Y Jelly

®

.

  Gently insert the probe tip no more than 1/2 inch or 1.3 cm into 

the rectum. Do not force the tip into the rectum if resistance is 

encountered.

  Wash the thermometer as recommended.
  Approximate measurement time is 8 to 10 seconds.
  Once used rectally, the thermometer should not be used orally for 

sanitary reasons.

CLEANING INSTRUCTIONS

Wash the area extending about 2” from the tip with warm, soapy 

water after each use and dry thoroughly.

OR

Wipe the area extending about 2” from the tip with 70% isopropyl 

alcohol after each use.

CHANGING THE BATTERY

When the “   ” appears and blinks, the battery needs to be 

replaced. Make sure you use the same type of battery and proceed 

as follows: Remove battery compartment lid. Use a non metal probe 

to remove battery. Insert new equivalent battery type (1.5V or LR41). 

Ensure battery is correctly positioned with the “+” facing up. Carefully 

replace the battery compartment lid. Properly dispose of the battery, 

keeping it from small children and heat.

CHANGING BETWEEN FAHRENHEIT & CELSIUS

1.  With the unit off, press and hold the ON/OFF button for 

  approximately 4 seconds to change the current setting.
2.  To convert results shown in F° to Celsius (C°) use the following 

equation:

 

C° = 5/9 x (F°- 32)
