In positive temperature conditions, objects being observed (surroundings and 
background) heat up differently because of thermal conductivity, thereby generating 
a high temperature contrast. Accordingly, image quality produced by the device will 
be higher. 
In low-temperature conditions, objects being observed (background) do, as a rule, 
cool down to roughly the same temperature, because of which temperature contrast 
is substantially reduced and image quality (detail) is poorer. This is a feature of 
thermal imaging devices.
Repair of the device is possible within 5 years.

questions about thermal imaging https://www.pulsar-nv.com/glo/support/faq/79 
Environment protection first!
Your appliance contains valuable material which can be recovered or recycled.
Leave it at a local civic waste collection point.
Attention! AXION thermal imagers require a licence when exported outside your country.
Electromagnetic compatibility. 
This product complies with the requirements of European standard EN 55032: 2015, Class A.
Caution: Operating this product in a residential area may cause radio interference.
TROUBLESHOOTING  
Poor image quality / 
reduced detection 
distances.
Image is unclear, with 
vertical lines and 
uneven background. 
Does not operate 
from external power 
source.
Coloured lines 
appeared on display 
or image has 
disappeared.
Image is too dark. 
Thermal imager does 
not power up.
Malfunction
 
Smartphone or tablet 
cannot be connected 
to the device.
Wi-Fi signal non-
existent or 
interrupted. 
 
When used in low 
temperature 
conditions, image 
quality of the 
surroundings is 
worse than in 
positive temperature 
conditions.
USB cable damaged.
Possible reason
Battery completely discharged.
The device is in an area with a large 
number of Wi-Fi networks that may 
cause interference.
Low brightness or contrast level set.
External power source discharged.
The device was exposed to static 
electricity during operation.
Calibration required.
Smartphone or tablet is out of range of 
a strong Wi-Fi signal. There are 
obstacles between the device and the 
receiver (e.g. concrete walls).
Device password has been changed.
Correction
Charge the battery.
Replace USB cable.
Perform image calibration according to 
Section 8 'Operation' of the Instructions.
 
Adjust brightness or contrast. 
After exposure to static electricity, the 
device may either reboot automatically, 
or require turning off and on again.
Charge external power source (if 
necessary).
Delete the network and reconnect using 
the device password.
Relocate smartphone or tablet into 
direct line of sight of the Wi-Fi signal.
To ensure stable Wi-Fi operation, 
relocate the device to an area with fewer 
Wi-Fi networks, or into an area with 
none.
These problems may occur during observation in difficult weather conditions (snow, 
rain, fog etc.). 
This table lists all the problems that may arise when operating the device. Carry out the recommended checks 
and repairs in the order shown in the table. If a defect should occur that is not listed in the table, or if it is 
impossible to repair the defect yourself, the device should be returned for repair.
