Warnings, Cautions and Notes
Definitions  WARNING Could cause bodily injury or death.  CAUTION Could cause damage to equipment or permanent loss of data.  NOTE provides useful information to the operator. Important Information – Read before using the Instrument  WARNING – Laser Radiation is emitted from this device. Do Not stare into Laser Beam. Class 2 Laser, 635 nm, 0.9mW  CAUTION - Never point the lens directly toward a strong radiation source (ie. Sun, direct or reflected laser beam, etc ), with power on or power off, as damage may result to the thermal detector used inside. Permanent damage may result!  CAUTION - The original shipping carton should be kept for use for future transportation. Do not drop, shake or impact the thermal imager excessively, 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 - Please remember to backup image data regularly to avoid losing important data.  NOTE - For maximum measurement accuracy, allow 3 to 5 minutes for 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 case. Unit does not contain any user serviceable parts. Repair should be performed by factory authorized technicians only.

again.
[2] Select/Auto key (Marked “A”) The “A” or attribute button performs 2 functions. a) The first function is modification of selected parameters. It is obtained by a quick press and release (less than 2 seconds), with this functions to modify their parameters. Subsequent presses will “scroll” through the available parameters. The selected function will be highlighted in yellow. The functions include:
●
Measurement points, areas, and lines
Points, areas, lines – switching the added points, areas and lines in the interface from Up to Down, press Menu to set properties, press C to delete the selected measuring objects.
●
Color Palette Pressing the left or right arrows will scroll through the available color palettes, displaying their name above the palette. The selected palette will become active after about 3 seconds of selecting it and will be set as the default power on palette.

3 Basic operation
3.1 Battery Installation and Replacement
3.1.1 Inserting or removing battery
Battery compartment is located inside the handle. Turn the cover counter-clockwise to remove. Remove battery for replacement.
Insert the battery (the battery contacts must face into the battery compartment).
Page 14

DALI
Replace the cover and screw down.
CAUTION:
Use only original manufacturer replacement battery. Use of incorrect battery may result in physical or electrical damage to the instrument due to incorrect voltage or physical size difference.
3.1.2 Replacing battery When battery displays empty and flashes for about 1 minute and 50 seconds, the
instrument displays a low battery dialog and shut down automatically after about 10 seconds.

3.2 Battery safety and usage
Batteries should be stored in an ambient temperature of -4° F (–20° C) to
67.9° F (+20° C). Lithium batteries will self-discharge during storage, so they should be fully charged before storage. Self-discharge may affect long term battery performance. Furthermore, it is recommended that the battery should be charged in a set time, as below; Ambient temperature of:
●-4° F (–20° C) to 67.9° F (+20° C), once every 6 months
● 67.9° F (+20° C) to 113° F (+45° C), once every 3 months
●113° F (+45° C) to 149° F (+60° C), once every month Battery should have greater than 50% charge prior to recharge. The ambient temperature for charging should be 32° F (0° C) to 104° F (+40° C). If under 32° F (0° C), the battery capacity will be diminished; if over 104° F (+40° C), the battery may overheat, resulting in permanent damage.
WARNING:
●
Never disassemble, incinerate or puncture battery
●Never short circuit the battery
●Keep battery dry
●Keep out of reach of children
●Always dispose of battery in accordance with local, state and federal regulations
