Basics of Your Thermometer
Normal Body Temperature
Troubleshooting
normal forehead
temp range
Temperature readings are different from person to person and also vary depending
upon the body location from which the temperature is measured. Forehead
temperatures tend to be comparable to oral temperatures and approximately 1˚ lower
than rectal temperatures for the same individual. Temperature readings are affected
by many factors including exercise, drinking hot or cold beverages prior to taking a
reading as well as technique.
“Normal” temperature refers to each individual’s average temperature while healthy.
You may want to measure and record your child’s temperature a few times when he
or she is well, so that you will know what is normal for your own child. On average,
temperature ranges are as follows:

Press and release the ON/MEMORY button. Thermometer runs a brief self-check, then beeps and displays the ready screen. The unit will default to FOREHEAD
MODE. POSITION LIGHTS at front of unit come on automatically. Prep the forehead by making sure it is clear of hair and sweat. If child has recently been in a very
warm or very cold environment, wait a few minutes for their skin to adjust to room temperature before taking their temp.
Once unit is positioned, press and hold the READ TRIGGER button on the rear of the thermometer for about 1 second or until the screen lights up, displays
temperature reading, and beeps (if not in mute mode.)
The unit gives one long beep when temp is in normal range. Thermometer gives additional beeps and the fever bar lights up when elevated temp is detected.
NOTE: High, prolonged fever requires medical attention, especially for young children. Please contact your physician. Fever chart included.
After a reading is complete, the WAIT icon will flash for 5 seconds. After those 5 seconds are complete, the unit will return to READY mode. Thermometer beeps
and shuts off automatically after about 30 seconds in READY mode.
This thermometer can also be used to take no-touch temperatures of liquids like bath water and milk/formula. Unit defaults into FOREHEAD MODE every time
you turn it on. To switch to LIQUID MODE, simply press the MODE button on the handle of the thermometer. NOTE: To return to FOREHEAD MODE, press MODE
button again. NOTE: Once in LIQUID MODE, positioning lights and fever bar are no longer needed.

This thermometer comes with the batteries outside of the unit. If this is your
first time using this unit, start with step 1 below.
Low Battery Warning:
• When the
icon appears on the display screen when
powering up and using the thermometer, the batteries are low
but may still work for a very short time.
• When the
icon appears and flashes by itself on the screen
the batteries are exhausted and need to be replaced.
To Install Batteries:
1 Use a Phillips head screwdriver to loosen battery cover screw.
Remove cover.
2 Remove old batteries
3 Insert two AAA (or equivalent) batteries,
correctly positioned with positive “+” and
negative “-” as shown in illustration.
4 Place the battery cover on the
thermometer and tighten the
screw to secure it in place.
• This is NOT an ear thermometer. Take temperature measurements from the center of
forehead. • Use caution when taking temperature readings of bath water and liquids. This product is not intended to touch
the person or item whose temperature is being measured. • ALWAYS supervise your child when using the thermometer.
NEVER allow your child to use it alone.
• NEVER allow children to play with this thermometer. It is not a toy. This is a sensitive electronic device and may be damaged
if not used properly under parental supervision. • DO NOT expose the thermometer to extreme temperatures, humidity, direct
sunlight or shock, and/or dust. • Keep battery out of child’s reach. Swallowing a battery could be fatal. Battery should not be
charged or placed into extreme heat as they may explode. • Used batteries should be disposed of properly.
Other Battery Information: We recommend alkaline batteries for longer battery life. DO NOT mix old and new batteries.
DO NOT mix alkaline, standard (carbon zinc) or rechargeable (nickel-cadmium) batteries. Non-rechargeable batteries are not
to be recharged. Rechargeable batteries are to be removed from the unit before being charged. Rechargeable batteries are only
to be charged under adult supervision. Only batteries of the same or equivalent type as recommended are to be used. Batteries
are to be inserted with the correct polarity. The supply terminals are not to be short-circuited. Check that all contact surfaces are
clean and bright before installing batteries. DO NOT disassemble for any reason other than inserting or replacing batteries.
Make sure the thermometer has been at room temperature for 30 minutes before use.

The POSITION LIGHTS are LED lights and are meant to help you feel confident about how you are aiming and distancing the unit.
-AIMING: The SENSOR LENS points at the area of the forehead between the two red POSITION LIGHTS. The right spot to aim the SENSOR LENS is
at the base of the forehead, just above the eyebrows. So, when properly positioned, the LOWER POSITION LIGHT should be between the eyebrows.
-DISTANCE: For accurate temperatures, the unit should be within 1.5 inches (4 cm) of the forehead. When the unit is 1.5 inches from the forehead,
the UPPER POSITIONING LIGHT will be directly above the LOWER POSITIONING LIGHT (vertically.) When closer or farther away, the lights move
away from each other in opposite directions.
Hint: If a child is uncomfortable seeing the thermometer coming toward his face, try turning the thermometer upside-down.
The POSITIONING LIGHTS work the same when the thermometer is upside down.
Memory

ON/MEM button again to toggle through up to 25 records.
Mute Function
To set to mute: While unit is ON, press the ON/MEM button for 3 seconds until you see
the “ ” icon appear. Then release ON/MEM button.
