Before Using, Familiarize Yourself with the Instrument
• To Scan: Depress the red button. The instrument will continually scan for the highest temperature
(peak) as long as the button is depressed.
• Clicking: Each fast click indicates a rise to a higher temperature, similar to a radar detector. Slow
clicking indicates that the instrument is still scanning, but not finding any higher temperature.
• To Retain or Lock Reading: The reading will remain on the display for 30 seconds after button is
released. If measuring room temperature, the temperature will remain on the display for only 5 seconds.
• To Restart: Depress the button to restart. It is not necessary to wait until the display is clear, the
thermometer will immediately begin a new scan each time the button is depressed.
• Pulse Timer: The thermometer has a built-in pulse timer. To activate, you should touch something

The Scan
One of the most important features of the thermometer is its ability to scan. It is a patented feature of
the instrument. Scanning is critical in obtaining the correct temperature, since there are temperature
gradients present not only inside the body, but across the entire surface of the body.
The object of scanning is to capture the highest temperature, the peak, in the area being scanned. As
long as the button is depressed, the thermometer will be continually sampling and recording the highest
temperature it measures.
Test it first on your hand to get comfortable with the concept.
Depress the red button, and keep it depressed. Scan the probe over the center area of your palm,
keeping the probe about a half an inch off the surface to avoid cooling the skin. The display will flash
SCAN, and there will be a soft but rapid clicking sound each time the sensor detects a temperature
higher than the one before. When the flashing and clicking slow to a little less than 1 per second, the
peak temperature has been reached. Any of the above indications can be used to assure the peak
temperature has been reached.
Remove the instrument from your palm and release the button and note the reading on the display.
The reading will be locked on the display for 30 seconds unless you press the button before that time.
Repeat the above steps and you should get the same, or very close to the same number, since your
hand will usually not appreciably change temperature very quickly.
