WARNING: Laser Radiation is emitted from this device.  This device features a Class 2 Laser, 635 nm, 0.9 mW.  Do NOT Stare into the Laser Beam.

CAUTION: Never point the lens directly toward a strong radiation source (for example, the sun, whether directly or reflected, or a laser beam) with power on or off, as permanent damage to the internal thermal detector may result.

CAUTION: The original shipping carton should be kept to use for future transportation.  Do not drop, shake, or impact the thermal imager excessively, whether in use or during transportation.

CAUTION: Store the unit in its original case in a cool, dry, well ventilated area away from strong electromagnetic fields.

CAUTION: Protect the surface of the lens from being stained or damaged by foreign objects such as sludge or chemicals.  Please replace the lens cap after use.

CAUTION: It is advisable to back up important images to an external device regularly to avoid losing important data.

NOTE: For maximum measurement accuracy, allow 3 to 5 minutes for the camera to stabilize after initial power up.

NOTE: Each camera is factory calibrated.  It is recommended that calibration be performed every 12 months.

CAUTION: Do not open camera housing.  The unit does not contain any user serviceable parts.  Repair should only be performed by factory authorized technicians.
