Please observe the following instructions for use in order to obtain the best from your thermal imaging camera and to ensure that it remains your constant companion for many years to come.

IMPORTANT SAFETY INFORMATION

Environmental influences
Note: Never point the lens of the device directly at intense heat sources such as the sun or laser equipment. The objective lens and eyepiece can function as a burning glass and damage the interior components.

Caution
Avoid touching the metal surface (cooling fins) after exposure to sunlight or cold.

Caution
Protection class IP66 is only achieved when all rubber covers are firmly closed.

Ergonomics note
Caution: Take breaks after longer periods of use to avoid wrist pain.

Risk of swallowing
Caution: Do not place this device in the hands of small children. Incorrect handling can cause small parts to come loose which may be swallowed.

Safety instructions for battery

Handle the device with care: Rough handling can damage the internal battery.
Do not expose the device to fire or high temperatures above 60°C.
Do not disassemble the device to access the battery. The battery is not meant to be replaced by the end user.

WLAN
This device is equipped with a WLAN function. Go to the menu and switch on the WLAN function. When activated, WLAN is indicated by a WLAN symbol in the upper right corner of the display. You can now connect your smartphone to the device via WLAN.
Note: When first used, the preset password for the WLAN connection to the device needs to be changed to prevent unauthorized access by third parties. The ZEISS Hunting App is required to change the password.

Default password: 12345678
To increase user comfort, the ZEISS Hunting App synchronizes your password on all logged-in devices. To increase the security of the connection, we recommend that you change your password. To extend battery life, we recommend that you only switch on the WLAN function in the device when the device needs to establish a data connection to the ZEISS Hunting App. ZEISS Hunting App Install the ZEISS Hunting App on your smartphone and open the app. Follow the steps shown there to connect to the ZEISS DTI The ZEISS Hunting App allows you to transfer images and videos to your smartphone, view live images, make settings, and use other functions. A more detailed description can be found in the help function of the app.

Note: To use the ZEISS Hunting App and its functions, ensure that your smartphone is connected to the ZEISS DTI 3 WLAN network.
Note : Every time you connect to the ZEISS Hunting App, the current date and time are automatically transferred from your smartphone to the device.
Note: Please note that you are not connected via the normal WLAN if you have established a WLAN connection to your ZEISS DTI 3. To return to the normal WLAN, disconnect your ZEISS DTI 3 from your smartphone.

USB port

Use the USB interface (14) on the bottom to charge your device or to transfer data (photos and videos) to your PC.
The ZEISS DTI3 connects as an MTP device using the USB interface. The device is automatically recognized and can be used immediately on computers with Microsoft Windows 10 operating system software. For computers with Apple Mac OS operating system software, you need to install additional third-party software to access the data stored on the device, such as “AndroidTM File Transfer”. ZEISS assumes no responsibility or guarantee for third-party software.

Tripod thread
A 1/4-inch standard thread (13) for standard tripods is located on the bottom of the device. Screw the device onto a tripod for more steady shooting.

Charging the device
Charge the device via the USB port (14) when the battery is empty. The battery charge level of the device is shown in the upper right corner of the display. When the charge level is low, the display changes to red. When the device is being charged, the LED (9) lights up red when the device is switched on and off. When the battery is fully charged, the LED (9) lights up green.

Replacing the lens cap
To replace the lens cap (2), unscrew the screws (3) using a screwdriver. Remove the retaining plate (4) and the defective lens cap (2). Fit the new lens cap (2) and retaining plate (4). Tighten the screws (3) using a screwdriver.

Care and maintenance of the device
Do not rub coarse particles (e.g. sand) from the lenses. Blow them off, or use a soft brush! 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 mold film from forming on the optics.
Your ZEISS DTI 3 requires no further special care.

Care and maintenance of the battery
Follow these steps to extend the battery life:

Avoid storing the device at high temperatures.
Avoid storing the device with a fully charged battery.
Avoid complete discharging of the device.

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.

Spare parts
Should you require spare parts for your device, e.g. the lens cap, please contact your specialist retailer, your local distributor, or our after-sales service. For Customer Service inquiries we are happy to take your calls from Monday to Friday from 8:00 a.m. to 4:30 p.m. (CET).
