Introduction

This thermometer is intended for scanning groups of individuals or monitoring an individual

for elevated temperatures. It is not a substitute for a clinical thermometer. Always use a

clinical thermometer when high accuracy body temperature measurements are required.

Considerations and Warnings

Read all instructions before using this product.

For the most accurate results, make reading with an ambient (room) temperature of

73 to 82°F (23 to 27°C)

Make sure the skin is dry and that no hair interferes with the measurement.

Do not immerse the meter in water.

Avoid touching and/or scratching the infrared sensor lens.

Always use a clinical thermometer to verify any abnormal temperature

measurements.

Clean the lens area by gently blowing with compressed air and use a damp swap

to wipe the lens. Do not use any solvents to clean the lens.

Measurement Notes

1. If the meter has been stored in a cold or hot environment, allow it at least 20 minutes

to acclimate to room temperature before making measurements.

2. To prevent transmission of disease, avoid direct contact with the skin.

3. After heavy exercise always wait at least 10 minutes before taking forehead

temperature readings.

Operating Instructions

1. Hold the meter from 0.5 to 4 inches (2 to 10cm) from the

forehead..

2. Point the meter at the center of the forehead and then pull

and hold the trigger to turn the meter on and begin testing.

3. For the best results, slowly scan towards the ear. Often the

area just above the temple provides the best measurement

because of it’s proximity to the temporal artery.

4. The meter will hold and display the highest temperature

measured.

5. The reading will remain in the display for approximately 6 second after the trigger is

released.

6. Press the

oF/oC button to change the measurement units.

7. “Hi” or “Lo” will appear in the display if the temperature reading is outside the range of

the meter.

Battery Replacement

When the low battery symbol appears on the display, replace the meter’s 9V battery.

The battery compartment is located on the bottom of the meter's handle. Open the

compartment by sliding the battery compartment cover off in the direction of the arrow.

Replace battery and re-install the battery compartment cover.
