Maintenance should be carried out no less frequently than twice a
year, and should consist of the following measures:
Wipe external plastic and metal surfaces clean of dust and dirt with
a soft cloth moistened with a synthetic cleaning agent.
Clean the electric terminals of the Battery Pack and device's
battery slot using a grease-free organic solvent.
Check the objective and eyepieces lenses. If required, remove dust
and sand (preferably by a noncontact method). Clean the external
surfaces of the lenses with products expressly designed for this
purpose.
Store the device in a carrying case. Remove the Battery Pack
for long-term storage.
MAINTENANCE AND STORAGE
TROUBLESHOOTING
The table presented below lists some potential problems that may occur
when using the device. If a problem encountered with the device is not
listed, or if the recommended action does not resolve the problem, the
unit should be returned for repair.
The thermal imager
will not turn on.
The unit does not
operate on external
power supply.
Battery Pack is discharged.
USB cable is damaged.
Charge the battery.
Replace USB cable.

Problem
External power supply is
discharged.
Charge the external power
supply (if necessary).
Place the device in line-of-sight
of the Wi-Fi signal.
The image is blurry,
with vertical stripes
and uneven
background.
The image is too
dark.
Poor image quality /
Detection range
reduced.
Calibration is required.
Brightness or contrast level
is too low.
Problems described may arise in adverse weather conditions
(snow, rain, fog etc.).
Carry out calibration according
to Section 9 “SENSOR
CALIBRATION”.
Adjust brightness/contrast with
the UP/DOWN buttons.
Smartphone or tablet
PC cannot be
connected to the
device.
No Wi-Fi signal or
erratic signal.
The device cannot
be powered on
with wireless remote
control.
When using the
scope at below zero
temperatures the
image quality is
worse than at
positive
temperatures.
Attention! The display of a thermal imager may have 1-2 pixels represented as
bright white or color (blue, red) dots which cannot be deleted and are not a defect.
The defective pixels on the sensor may proportionally increase in size when
digital zoom is activated.

Problem
Password in the unit was
changed.
Delete network and connect
again inserting the password
saved in the device.
The device is beyond reliable
Wi-Fi range.
There are obstacles between
the device and the signal
receiver (i.e. concrete walls).
There are too many Wi-Fi
networks in the area where the
device is located which may
cause signal interference.
To ensure stable Wi-Fi
performance, move the device
to an area with few or no Wi-Fi
networks.
Remote control is not
activated.
Low battery.
Activate the remote control
according to instructions.
Install a new CR2032 battery.
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.
