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.
