Caution!
Risk of injury:
• The product is equipped with a class 2 laser. If the sign on the device is not written in the
language of your country, please affix the sign (page 2) onto the device.
• Do not point the laser beam at mirrors or other reflective surfaces. The uncontrolled reflect-
ed beam may strike people or animals.
• Do not aim too close at hot or dangerous targets.
• Keep this device and the batteries out of reach of children.
• Small parts can be swallowed by children (under three years old).
• Batteries contain harmful acids and may be hazardous if swallowed. If a battery is swal-
lowed, this can lead to serious internal burns and death within two hours. If you suspect a
battery could have been swallowed or otherwise caught in the body, seek medical help
immediately.
• Batteries must not be thrown into a fire, short-circuited, taken apart or recharged. Risk of
explosion!
• Low batteries should be changed as soon as possible to prevent damage caused by leaking.
• Never use a combination of old and new batteries together, nor batteries of different types.
• Avoid contact with skin, eyes and mucous membranes when handling leaking batteries. In
case of contact, immediately rinse the affected areas with water and consult a doctor.
Important information on product safety!
• Do not expose the device to extreme temperatures, vibrations or shocks.
• Protect the unit from large or abrupt ambient temperature changes.
• Do not leave the unit near objects of high temperature.
• Do not immerse the unit in water. Water can penetrate and cause malfunction. Protect it
from moisture.
• Check the housing before using the device. Do not use the device if it seems to be damaged.
Check for cracks or missing plastic parts.
• Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the unit's optics.
EMC/RFI
• Protect the unit from EMI (Electro Magnetic Interference) from induction heaters and
microwave ovens and Electro Static Discharge. Readings may be affected if the unit is
operated within a radio frequency electromagnetic field strength of approximately 3 volts
per meter, but the performance of the instrument will not be permanently affected.

3. Getting started
• Open the battery compartment.
• The battery compartment is on the inside of the handle. Open the battery compartment
cover downwards.
• Insert two new batteries 1,5 V AAA. Ensure that the batteries polarity is correct.
• The device will alert you with a beep.
• Close the battery compartment again. The cover is properly inserted in the housing, as soon
as a click is heard.
4. Use
• Press the measuring button on the inside of the handle to turn on the device.
• The device will alert you with a beep.
• All segments will be displayed for a short moment.
• The backlight is automatically activated (default). The symbol
• Press the button to turn off or turn on the backlight. The symbol disappears or appears on
the display.
• The laser is automatically activated (default). The symbol
• Press the button to deactivate or activate the laser. The symbol disappears or appears on
the display.
• As long as you keep the measuring button pressed, the display shows "SCAN" and the meas-
ured temperature.
• With the laser the measuring point can be focused exactly.
• Release the measuring button.
• On the display appears HOLD.
• The latest measured temperature stays for a few seconds on the display.
• When the device is not used, it will automatically switch off after a few seconds.
• Press the °C/°F button to change the temperature display from °C (default) to °F.
5. Distance, Spot Size, and Field of View
• As the distance (D) from the object increases, the spot size (S) of the area measured by the
unit becomes larger a ratio D:S = 12:1 (e.g. 120 cm distance = 10 cm spot size). To get the
most accurate temperature reading, aim at the target as near as possible.
• Should the distance be too great, there is a risk that the temperature has also been taken out-
side the aimed target.
Please take note of the following:
• Not recommended for use in measuring shiny or polished metal surfaces (stainless steel,
aluminium, etc.).
• The unit cannot measure through transparent surfaces such as glass or plastic. It will meas-
ure the surface temperature of the glass instead.
6. Care, maintenance, battery replacement
• The sensor lens is the most delicate part of the thermometer. Please protect the sensor part
from dirt.
• Clean your instrument with a soft damp cloth. Do not use solvents or scouring agents.
• Remove the batteries if you do not use the product for a long period of time.
• Change the batteries, when the battery symbol appears on the display.
• Confirm the device is power off before changing the batteries.
