• Do not open the product for reasons other than replacing batteries. The
laser beam is dangerous to eyes. Have the product repaired only through
an approved technical site.
• Verify the product's operation by measuring on a known temperature
source. Do not use the product if it operates incorrectly or abnormally.
• Do not use the product if it is damaged.
• See emissivity information for actual temperatures. Reflective objects
result in lower than actual temperature measurements. These objects
pose a burn hazard.
• Remove the batteries if the product is not used for an extended period of
time, or if stored in temperatures above 122 °F (50 °C). If the batteries are
not removed, battery leakage can damage the product.
• Replace the batteries when the low battery indicator shows to prevent
incorrect measurements.
• Use only AA alkaline batteries and follow all battery care from the
manufacturer.
• Do not leave the product on or near objects of high temperature.
• For use by competent persons only.
• Have an approved technician repair the product.
Caution
W
To prevent personal injury and for safe operation and maintenance of the
product:
• Batteries contain hazardous chemicals that can cause burns or explode. If
exposure to chemicals occurs, clean with water and get medical aid.
• Be sure that the battery polarity is correct to prevent battery leakage.
• Do not short the battery terminals together.
• Keep batteries clean and dry.
To avoid damaging the product under measurement, protect it from the
following:
• EMF (electro-magnetic fields) from arc welders and induction heaters.
• Static electricity.
• Thermal shock (caused by large or abrupt ambient temperature changes
— allow 30 minutes for the product to stabilize before use).
• Do not leave the product on or near objects of high temperature.
