• A – Automatic calibration every 2 minutes

• M – Manual calibration triggered by the user by a long press on the F key.

• S – Silent calibration triggered by the user by a long press on the F key. During use, the image quality gradually decreases due to the changing background temperature of the sensor. This is compensated for by calibrating the sensor at regular intervals. For this purpose, an internal aperture is closed for a short time and the remain- ing signal is subsequently subtracted from the image signal as background noise. You will recognise the calibration process by a quiet clicking sound and you will see the last image signal as a still image during this time. When the unit is switched on, several calibrations are automatically performed in the first few seconds, regardless of the calibration mode selected.

• In M mode, you determine the timing of the calibration with the internal shutter your- self. Perform a manual calibration if you notice a deterioration in picture quality that manifests itself in the form of increased picture grain or streaking.

• You trigger the S mode in the same way as the M mode. However, the internal shut- ter is not used, so this process is completely silent. Notice: Cover the front lens during the calibration process. Otherwise you will see a superimposed "ghost image".5. Input mode Input mode allows you to select which functions are controlled directly by a click or a long press on a button, so that you do not have to call up the menu first.

Perform cleaning twice a year.

Do not use electrically conductive materials for cleaning.

Wipe the external surfaces of metal and plastic parts free of dust and dirt with a cotton cloth. Storing the battery

When not in use, remove the battery from the KEILER or the charger.

Store the battery in a dry place, protected from light and frost.

To avoid unnecessarily shortening the life of the battery, when the battery is not in use for an extended period of time make sure the charge level is approx. 80%.

Check the charge level every 6 months.

This overview contains a list of the most common problems that may occur when using the unit.

Carry out all recommended checks as described in the table.

KEILER Malfunction Possible reason Remedy The thermal imager cannot be switched on. In the starting process, the KEILER switches o again aer the start logo has been displayed. The battery is not suciently charged. Charge the battery for half an hour before switching the unit on again. The device cannot be powered by an external power source. The external power source is not strong enough. Use an external power source with a min. charging current of 5V / 2A. The USB cable is damaged. Replace the USB cable. The battery is very slow to charge. Using a power supply unit with insucient power. Use only the power supply unit supplied. The device is not switched o. Switch the device o (OFF) so that charging works reliably. The battery is deeply discharged. Charging takes a significantly longer time for deeply discharged batteries. The image is blurred, with thin vertical lines or shadows. Calibration needed. Perform an image calibration. Aer calibration, a "ghost image" can be seen super- imposed on the scene. Calibration mode S was selected and the front lens was not covered during calibration. Perform a repeat calibration with the front lens covered. Low image quality / reduced detection range. These problems can occur under adverse weather conditions (high humidity, snowfall, rain, fog, etc.). During long periods of constant weather conditions without sunshine, and especially in rainy weather, the observed objects converge to approximately the same temperature, so that the tem- perature dierence is considerably reduced, and the image quality suers as a result. This circumstance is due to physical causes and is not a defect of the thermal imager.Malfunction Possible reason Remedy Photo or video recording does not work. 20 seconds have not elapsed aer the unit was booted up. Wait 20 seconds aer switching on the unit before you start taking photos or videos. Some defective pixels cannot be permanently deleted. The defective pixel is not recognised by the unit. Switch the calibration to M mode and wait until the pixel is very clearly visible. Then carry out the error pixel correction ("Advanced settings" menu). Then switch back to A mode. The LIEMKE app does not connect to the unit. WiFi is not activated. Activate the WiFi of the unit in the menu. The mobile terminal is not connected to the KEILER-WiFi. Connect your mobile end device to the WiFi of KEILER. Battery Malfunction Possible reason Remedy The battery charges very slowly or not at all. Using a power supply unit with insucient power. Use a suitable power supply unit as spec- ified in the operating instructions for the KEILER or CHARGER-K. The battery is deeply discharged. Charging takes a significantly longer time for deeply discharged batteries.

Do not dispose of waste electrical equipment and batteries in the household waste. Hand in used electrical appliances and batteries at the local recycling collection point. Batteries should be fully discharged when disposed of. We are participating in INTERSEROH+ Verbund. The device compo- nents can be taken to plastic and metal recycling for disposal. Disposing of the battery
