ZEISS DTI 4/50 - Thermal Imaging Camera Manual

Scope of Supply

Installing/removing the battery

The ZEISS thermal imaging attachment is equipped with a battery. It cannot be removed.

Attaching the thermal imaging attachment

An adapter is required to attach it to an optical device, e.g. a riflescope. To expose the thread for attaching the adapter, turn the retaining ring (6) as far clockwise as possible in the direction of the thermal imaging attachment. Handtighten your external adapter clockwise onto the device. Turn the retaining ring (6) counterclockwise as far as it will go. Hold the retaining ring (6) in place with one hand. Use your free hand to grasp the adapter and turn it as tightly as possible clockwise towards the retaining ring (6).
Note: Check the legal and regional regulations in your country before using the ZEISS DTC 4 in combination with an optical sight.

TECHNICAL DATA

Overview

Power on/off

Press and hold the on/off button (3) (approx. 1.5 seconds) to switch on the device. Press and hold the on/off button (3) to switch off the device again.
Note: The on/off button (3) must be pressed until the OFF symbol appears on the display. Only then can the on/off button (3) be released and the device switches off. If the on/off button (3) is released before the OFF symbol is displayed, the device does not switch off but switches to standby mode.

Standby mode

Briefly press the on/off button (3) to switch the device to standby mode. Briefly press the on/ off button (3) again to switch the device back to observation mode.
To further conserve battery power and extend running time, the ZEISS DTC 4 offers Smart Standby with a built-in motion sensor. This automatically detects the position of the thermal imaging attachment and activates standby mode at 45° lateral inclination or 70° downward or upward inclination. As soon as the thermal imaging attachment returns to its normal position, the device automatically switches back to observation mode. You can deactivate this function in the menu under "Smart Standby".

Calibration

The device can be calibrated automatically (Auto Calibration = On) or manually (Auto Calibration = Off). This can be set in the main menu or via the right arrow button (4) in observation mode.
In automatic mode, the device automatically performs a calibration by closing and opening an internal shutter when necessary. A gentle click should be heard. In this mode, you also have the option of performing the calibration manually. Briefly press the right arrow button (4). The device activates the shutter and calibrates itself. The device is now calibrated again.
If automatic calibration is switched on, the device displays a circle two seconds before the shutter is calibrated. This indicates that a calibration will take place shortly.
To perform a manual, silent calibration, first switch to observation mode by pressing and holding the right arrow button (4) in manual mode. To calibrate, cover the lens and then briefly press the right arrow button(4).

Note: Always cover the lens when performing a manual calibration. Otherwise the sensor cannot calibrate correctly and the image will deteriorate, e.g. ghost images. If you forget to cover the lens during a manual calibration, repeat the calibration procedure with the lens covered.

Observation mode

Turn the focusing turret (2) to bring the scene into focus.

Color modes

The scene can be displayed in different color modes. Briefly press the menu button (5) to change the observation mode. When changed, the selected mode is shown on the display as text for about 2 seconds. You can activate or deactivate the desired modes under the system menu item "Color Modes". When changing with the menu button (5), only the active modes are changed. The following color modes are available:

• White Hot: Cold areas are displayed here in black and warm areas in white.
• Black Hot: Cold areas are displayed here in white and warm areas in black.
• Red Hot: Cold areas are displayed here in black and warm areas in white. In addition, the warmest areas are shown in yellow to red.
• Rainbow: A varied color palette displays cold areas in black to blue and warm areas in yellow to white.
• Green Hue: The image is displayed in green levels here. Cold areas are displayed in dark green and warm areas in light green.
• Red Hue: The image is displayed in red levels here. Cold areas are displayed in dark red and warm areas in light red.
• Dark Hue: Cold areas are displayed here in a sepia tone and warm areas in violet.
• Night Eye: This is a combination of White Hot and Black Hot. Cold areas are displayed here in black to dark brown and warm areas in sepia to light brown.

Shooting mode

You have the possibility to take photos and make videos.

Personal data when you dispose of or pass on your ZEISS device

Before passing on the device to a third party, please perform the factory reset to delete data and verify it has been deleted. By doing so, you help maintain your privacy and data security.

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.
Note: If the device is switched on and has more than 10% charge, the LED lights up green constantly.

ZEISS Hunting app

Install the ZEISS Hunting app on your smartphone and open the app. To connect to the thermal imaging attachment, activate WLAN on your thermal imaging attachment and follow the steps displayed in the app. The app enables you to make settings, use the ZEISS DTC 4 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

There are two ¼-inch standard threads (12) on the underside 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

Please do not wipe coarse particles from the lenses (e.g. sand), 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 mold 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.
