Pulsar TELOS - Page 75

Possible cause – Brightness or contrast level is too low .
Solution – Adjust the brightness or contrast level in the Quick Menu .
Colour bars appear on the display or the image disappears
Possible cause – The device was exposed to static charges during operation .
Solution – When the exposure to static charges is over , the device may either
reboot automatically or require to be switched off and on again .
The image of the object being observed is missing
Possible cause – The object is behind glass , which obstructs thermal vision .
Solution – Remove the glass .
Poor image quality / Detection range reduced
Possible cause – These problems may occur during observation in adverse
weather conditions ( snow , rain , fog , etc .).
The image quality during the device operation at below zero temperatures is
worse than at positive temperatures
Possible cause – In warm climates , objects in the background of a thermal
image heat up differently because of thermal conductivity , generating a high
temperature contrast and a sharper thermal image .
In cold climates , objects in the background of a thermal image will cool down
to roughly the same temperature , which leads to a greatly reduced
temperature contrast and a degraded image quality . This is normal for all
thermal imaging devices .
Smartphone or tablet PC cannot be connected to the device
Possible cause – Device password has been changed .
Solution – Delete the network and connect again using the password saved
in the device .
Possible cause – The device is in an area with too many Wi - Fi networks that
may be causing signal interference .
Solution – To ensure a stable Wi - Fi connection , relocate the device to an area
with fewer or no Wi - Fi networks .
Possible cause – The device has a 5 GHz network enabled , but the
smartphone only supports 2.4 GHz .
