3. Replace the battery with a new 9 V battery. 
4. Close the battery compartment. 
 
Warning: Do not puncture batteries or throw them in fire as they 
may explode. Do not attempt to recharge non
batteries (alkaline). Dispose of batteries in accordance with local 
regulations. Keep batteries away from children. 
7. Operation 
1. Aim the IR sensor [B] at the target and press the measurement 
trigger [D] to display the target’s surface temperature. A red laser 
spot appears on the target during measurement. 
2. The distance-to-target ratio is 12:1. This means that, for example, at 
12 cm, the target must be larger than 1 cm to get a proper 
measurement. Make sure the target area is within this field of view. 
3. The device can measure temperatures in °C or °F. Press the mode 
key [F] while the device is on to switch between measurement units. 
The corresponding symbol (°C or °F) appears on the display. 
4. When you release the measurement trigger [D], the hold mode is 
automatically activated: the last measurement value remains on the 
display until you press the measurement key again, or until the device 
shuts off automatically (after approx. 7 seconds). 
5. Note that the display is always on, while the laser is only on during 
measurement.
