SENSOR CALIBRATION MODE

• Short press the Zoom button to change between S (shutter) and B (background) calibration mode.
  During use, the image will deteriorate gradually because of changing background temperature of the sensor. This needs to be equalized by periodically calibrating the sensor. In S mode, calibration is done automatically via an internal shutter that makes a faint clicking noise. The calibration can also be done
  manually by pressing the zoom and photo buttons simultaneously during viewing if a deterioration in image quality is detected during use. In B mode, no automatic calibration is done. Pressing the zoom and photo buttons simultaneously during viewing performs a manual shutterless calibration. During calibration in B mode, the lens cover needs to be closed (this is also being prompted by an icon appearing in the display). Otherwise, an image of the scene viewed during calibration will be imparted on the sensor. This can be corrected by a proper calibration.

PICTURE IN PICTURE (PIP)

TECHNICAL INSPECTION

A technical inspection of the device is recommended before use.

• Check the external appearance of the device. There should be no cracks in the casing.
• Check the condition of the lens and eyepiece: There should be no cracks, greasy spots, dirt, or other deposits.
• Check the condition of the rechargeable battery: This should be charged.
• Check the electrical contracts: There should be no presence of salts or oxidation.

MAINTENANCE

Maintenance should be carried out at least twice a year and consist of the following actions.

• Wipe the external surfaces of metal and plastic parts free of dust and dirt with a cotton cloth. Silicone grease may be used for this.
• Clean the electrical contacts of the unit using a non-greasy organic solvent.
• Check the glass surfaces of the eyepiece and the lens. If necessary, remove dust and sand from the lenses (preferably using a non-contact method). Cleaning of the external surfaces of the optics should be done with substances designed especially for this purpose.

TROUBLESHOOTING

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.

Charge the battery
Does not operate from the external power source.| USB cable damaged External power source discharged| Replace USB cable Charge external power
source (if necessary).
Image is unclear, with vertical lines and uneven background| Calibration required| Perform image calibration according
to Section 21 „Sensor Calibration Mode“ of
the Manual.
The image is too dark.| Low brightness level set.| Adjust display brightness.
Colored lines appear on display or the
image has disappe­ rated.| The device was exposed to static electricity during
operation.| After exposure to static electricity, the device
may either reboot automatically or require
turning off and on again.
Poor image quality / reduced detection distance| These problems may occur during observation in difficult weather conditions (high humidity, snow,
rain, fog, etc.).
Smartphone or tablet cannot be connected to the device| The device password has been changed.| Delete the network and reconnect using the
device password
| The device is in an area with a large number of Wi-Fi networks that may cause interference.| To ensure stable Wi-Fi operation, relocate the
device to an area with fewer Wi-Fi networks, or
into an area with none.
Wi­Fi signal nonexistent or interrupted| The device is outside the area of Wi-Fi coverage. There are obstacles between the device and the receiver (e.g. concrete walls.)| Relocate the device into the direct line of sight
of the Wi-Fi signal.
When used in lowtem­ temperature conditions, the image quality of the surroundings is worse than in positive tempe­ rature conditions.| In positive temperature conditions, objects being observed (surroundings and background) heat up differently because of thermal conductivity, thereby generating a high-temperature contrast. Accordingly, the 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 the image quality (detail) is poorer. This is a feature of
thermal imaging devices.
