Cooperation on device safety

Please take an active role in protecting the IT security of your device by using the ZEISS Hunting App and installing new firmware updates as soon as they become available.

Firmware update

A firmware update can be carried out using the ZEISS Hunting App. Follow the instructions for this in the ZEISS Hunting App.
Note: If you initiate an update via the ZEISS Hunting App, you must confirm this again on the device for security reasons.
Note: Make sure that the device is fully charged before updating the firmware. Do not switch off the device during the update, otherwise it may be damaged.

LED status

Note: The LED is located under the cover for the USB charging socket.

ZEISS Hunting App

Install the ZEISS Hunting App on your smartphone and open the app. To connect to the thermal imaging attachment, activate Bluetooth on your thermal imaging attachment and follow the steps displayed in the app. The app enables you to make settings, use the ZEISS DTC 3 via remote control mode and use the simplified zeroing mode. A more detailed description can be found in the help function of the app.

Charging the device

Charge the device via the USB port (7) when the battery is empty. To do this, first open the rubber cover on the side of the device (9).
The battery charge level is shown in the upper left corner of the display. When the charge level is low, the display changes to red. When the device is being charged, the LED (8) lights up red when the device is switched on and off. When the battery is fully charged, the LED (8) lights up green.

Replacing the lens cap

To replace the protective lens cover (1), loosen the front part of the lens cover by turning it counterclockwise. Unscrew the lens cover completely. Then screw the new lens cover back on.

Replacing the USB cover

To replace the USB cover (9), unscrew the screws (13) using a screwdriver. Remove the retaining plate (14) and the defective USB cover (9). Insert the new USB cover (9) and the retaining plate (14). Tighten the screws (13) using a screwdriver.

Adapter

Two ¼-inch standard threads (12) are located on the bottom of the device. These offer you the option of attaching an adapter here, e.g. for a Picatinny rail.

Care and maintenance of the device

Do not wipe off coarse dirt particles (e.g. sand) from the lenses, rather blow them away, or use a fine brush to remove them! Over time, fingerprints can corrode the lens surface. Breathing on the lens and polishing it with a clean optical cleansing cloth is the easiest method of cleaning the lens surface. Dry storage and keeping the outer lens surfaces well ventilated, especially in the tropics, helps to prevent a possible mould film forming on the optics. Your thermal imaging attachment requires no further special care.

Software updates

Within the scope of the statutory warranty (2 years from the transfer of risk of the goods - according to German law), we will provide appropriate updates to remedy defects. Generally, updates are used for security-related aspects or to eliminate functional impairments and do not include new functions of the software. Insofar as the provision of new functions is necessary to remedy security aspects, this shall not in principle constitute a claim to new functions as such.
After the legal warranty period has expired, we will of course endeavor to provide you with appropriate further updates. However, there is no entitlement to this.

Troubleshooting

Care and maintenance of the battery

Follow these steps to extend the battery life:

• Only store the device at temperatures ranging between 0 and 35°C.
• Avoid storing the device with a fully charged battery.
• Avoid complete discharging of the device.
