Solution
Presence of dots is caused by peculiarities of microbolometer or display production
technology and is not a defect.
☐
The device cannot be powered on with wireless remote
control
Possible cause
Remote control is not activated.
Solution
Activate the remote control according to instructions.
Possible cause
Wireless remote control low battery.
Solution
Install a new CR2032 battery.
☐
When using the scope at below zero temperatures the
image quality is worse than at positive temperatures
Possible cause
Because of variations in thermal conductivity, objects (surrounding environment,
background) under observation become warm more quickly at above-zero temperatures,
which allows higher temperature contrast and, thus, the quality of the image produced by
a thermal imager will be better.
At low operating temperatures, objects under observation (background) normally cool
down to roughly identical temperatures, which leads to lower temperature contrast, and to
image quality (precision) degradation. This is normal for thermal imaging device.
☐
Rangefinder will not measure distance
