PULSAR AXION COMPACT XG35 Manual

Unlike night-vision devices that are based on electron-optical converters, thermal vision monoculars do not require an external light source and are resistant to the effects of bright light.

Axion Compact monoculars can be used for night-time hunting, observation and terrain orientation, and carrying out rescue operations.

Calibration is required.

Solution

Perform the calibration according to Calibration Mode section.

Solution

If the image does not clear after calibration, you need to recalibrate.

Possible cause

After turning on the device, it takes some time for the sensor temperature to stabilize. This is normal and is not a defect.

Possible cause

Manual calibration has been performed with the lens cover open.

Solution

Check the Calibration Mode, close the lens cover and calibrate the device.

Possible cause

Brightness or contrast level is too low.

Solution

Adjust the brightness or contrast level in the Quick Menu.

Possible cause

These problems may occur during observation in adverse weather conditions (snow, rain, fog, etc.).

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.

Solution

Switch the device’s Wi-Fi bandwidth to 2.4 GHz.

Possible cause

Smartphone or tablet is out of range of a strong Wi-Fi signal. There are obstacles between the device and the smartphone or tablet (e.g., concrete walls).

Solution

Relocate smartphone or tablet into the Wi-Fi signal line of sight.

Possible cause

The device was exposed to static electricity during operation.

Solution

After exposure to static electricity, the device may either reboot automatically or require turning off and on again.

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.

Possible cause

The object is behind glass, which obstructs thermal vision.

Solution

Remove the glass.

Solution

To replace the USB cable, contact your local distributor.

Self-repair of the cable is prohibited.

The ability to use a USB cable from other manufacturers with the device may be limited.
