05. BASIC OPERATION

Before use

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: They should be clean and free of damage.
Check the condition of the battery: It should be charged if necessary.
Check the USB connection and the rubber plug: The contacts should be clean and free of oxidation and the plug should be put firmly in place before use to ensure protection against moisture.

Lens focus ring

Focus the objective lens for different distances by turning the focus ring until the image is sharp.

Flip-Cover

The device comes with a protective flip-cover installed.

Open the cover by pushing on the tabs opposite the hinge.

The cover snaps in place as the hinge opens

completely and sits almost flush with the housing. The cover can be rotated to open to the left, right or top. The cover can be removed from the device by grabbing the closed cover at the back of the hinge and pulling it away from the device. It can be reinstalled by pushing it onto the finishing lip of the objective and snapping it in place.

Adapter threads and thread cover

At the rear of the device there are threads (M43x0.75) for attaching to a clip-on adapter. The device is delivered with a protective thread cover with a rubberized eyecup. When using the device as a clip-on, this thread cover needs to be removed by unscrewing it counterclockwise. 26

Three position switch lever

Move the lever to the desired position for OFF, S (standby) and ON settings.

The white dot is partly visible in standby mode and completely visible when ON, making the status of the device easily discernible in dim light conditions. Startup time from OFF to ON is 5 seconds for image display. Images and videos can be taken from 20 seconds after startup. The standby function switches off the display and interrupts Wi-Fi transmission (when Wi-Fi is active) to save battery power and cut light emission from the device. When switching from Standby to ON, image and responsiveness are there immediately.

Button Panel

On the top of the device is a panel with three large buttons. There are two different input options for each button:

• Click (short press)
• Long press

A click consists of pressing and releasing a button immediately. A long press consists of pressing and holding a button for at least 0.4 seconds.

• Additionally, you can exit the menu from any point by pressing the MENU button for 2 seconds.

Default Screen

The standard screen (when not in the menu) shows icons for the selected gun profile

(G1-G3), battery charge status and calibration mode (A, M, S). The Wifi symbol is shown in the top center of the image only when Wifi is activated.

For use as a clip-on, the position of the information displayed on the screen can be adjusted to the lowest magnification of the rifle scope. This keeps the information visible but at the edge of the field of view without blocking the view of the target. The icon display setting can be changed in the Shot Alignment submenu and saved together with the alignment setting for the respective riflescope.

Menu navigation

Enter the menu by long pressing the MENU button.
The menu on the left of the screen consists of menu icons. There is a short information text shown in the top center of the screen when a menu item is selected.
Navigate to the desired menu item with the UP and DOWN buttons and select the desired menu item with a click of the MENU button. Further submenu items, if available, are indicated by arrows above and below the selected submenu item and can be selected with the UP and DOWN buttons.
Choose a menu or submenu function by clicking the MENU button.
Save and return to the previous menu item by long pressing the MENU button.
To completely exit the menu from any point in the menu, press and hold the MENU button for 2 seconds.

06. INPUT MODES

The LUCHS-1 has three different input modes with specific functions directly accessible by a click or a long press of the buttons. Input Modes can be changed in the Menu item "Input Mode".

Standard Mode

Standard Mode is the default mode that is suitable for most use cases. Brightness and Image Mode as well as the Photo and Video Recording functions are directly accessible via the button panel. The menu is always accessed with a long press of the MENU button and manual calibra

(01)

click: Brigthness

long press: Calibration

(02)

click: Image mode

long press: Menu

(03)

click: Take photo

long press: Start/stop video

tion is always performed with a long press of the UP button.

Basic Mode

Basic Mode is a simplified input interface for users that do not want to change their settings frequently, for example for only hunting at night and with a fixed set of preferred settings. The menu is accessed with a long press of the MENU button and manual calibration is performed with a

(01)

long press: Calibration

(02)

long press: Menu

(03)

long press of the UP button. There are no additional functions available via the button panel. Photo and video recording functions are deactivated. Changes to settings like brightness and color mode can be done by entering the menu.

Basic mode provides maximum protection against accidental changes to settings and lowers battery consumption by disabling media functions, providing up to 9 hours of operation on a single battery charge.

Custom Mode

Custom Mode allows the user to personalize the button panel functions based on his usage preferences. Functions that are often used can be directly accessed via the button panel and functions that are not

(01) click: Brightness / Color Mode / Image Mode / none long press: Calibration

(02) click: Brightness / Color Mode / Image Mode / none long press: Menu

(03)
click: Take photo / none
long press: Start/Stop video / none

needed regularly can be switched off to prevent accidental activation. For how to assign functions to the buttons, see "Input Mode" in the Menu section of this manual.

07. MOMENTARY 2X ZOOM FUNCTION

Pressing the UP and DOWN buttons simultaneously activates the momentary 2x zoom function. The 2x zoom is only active while the buttons are pressed. When releasing the buttons, the magnification automatically reverts back to the default 1x zoom.

Important: This function is meant for target identification. Shooting with the zoom function activated may result in a change of point of impact. A warning appears on the screen while the zoom function is activated.

08. MENU FUNCTIONS

When changed via the button panel, brightness cycles from 1 to 10 and then goes to 1 again. When changed via the Brightness menu item, brightness can be increased or decreased with the UP and DOWN buttons and it stops at 1 and 10 respectively. This way the brightness can be increased or decreased deliberately which is especially useful in the dark when you want to choose a lower brightness setting without first cycling through the higher brightness settings. Brightness is the first menu item so it is quickly accessible when the customizable buttons in Custom Mode are used for other functions.

Image Mode

Select Sun or Rain.
Choose a mode based on the properties of the scene and your preferences.

Sun mode shows a smooth and natural looking image for scenes with good inherent contrast like on sunny days or nights after a sunny day when objects in the landscape have different temperature levels. It is also useful for seeing fine detail in the warm target.

Rain mode enhances the contrast and makes fine structures visible in scenes with low inherent contrast. It is especially useful to show details of the landscape in rainy or overcast conditions.

Color Mode

Cycle through the activated color modes. Color Modes can be selectively deactivated in the Advanced Settings submenu "Color Mode active/inactive". Deactivated color modes will not show up in this menu so you only cycle through modes that you find useful. The available Color Modes are:

• WH - White Hot: For accurate identification, good for nighttime use because of darker background
• BH - Black Hot: Provides a more realistic visual impression with dark target on brighter background
• ED - Extra Dark: Based on White Hot mode with lower overall brightness and a warm tint, ideal protecting the natural night vision ability of the eye
• RH - Red Hot: For fast detection of heat sources
• RB - Rainbow: For showing small temperature differences

Use case descriptions are only guidelines, use of color modes is largely a matter of personal preference.

Input Mode

Input Mode allows you to select what functions are controlled directly by button click or long press so you don't have to enter the menu to change them. See chapter 05. for information on the Standard and Basic input modes.

Custom Mode button configuration

In Custom Mode, button functions can be configured to the preferences of the user.

To assign the button functions in the "Custom" submenu, short click the MENU button to toggle through the input functions The functions for click are on top, long press on bottom for each button.
Change the input functions with the UP and DOWN buttons.
Switch to the next button function with a click of the MENU button.
Long press the MENU button to save the settings and return to the Input Mode submenu.

The configuration options are:

UP (click): Brightness / Color Mode / Image Mode / none
UP (long press): Calibration

MENU (click): Brightness / Color Mode / Image Mode / none
MENU (long press): Enter Menu

DOWN (click): Take Photo / none
DOWN (long press): Start/Stop Video / none

Calibration Mode

In this menu item you can choose the calibration mode.

A - Automatic calibration every 2 minutes
- M - Manual calibration triggered by the user with a long press of the UP button.
- S - Shutterless calibration triggered by the user with a long press of the UP button.

During use, the image gradually deteriorates because of the changing background temperature of the sensor. This is compensated for by periodically calibrating the sensor. Calibration is performed by activating an internal shutter and equalizing the sensor out-

put. The shutter makes a very faint clicking noise and the image freezes for 0,5s during calibration. When starting the device, automatic calibrations are performed in the first seconds regardless of the calibration mode.

In M mode you can choose the time when the image briefly freezes, which is especially convenient when using the device as a clip-on for shooting to ensure that the image freeze does not occur at the moment you want to take the shot. Perform a manual calibration when you observe deterioration of image quality such as graininess or banding.

$ Mode is triggered by the user like M mode, but does not use the internal shutter for completely silent operation.

Important: Close the lens cap during calibration.

Activate/deactivate the WiFi connection.

A WiFi symbol is displayed in the top center of the screen when WiFi is activated. For further information about the APP and how to connect the LUCHS-1 to your mobile device, visit: https://liemke.shop/medien

The LUCHS-1 is adjusted from the factory so that you have the same line of sight with the device attached as a clip-on that you have with your riflescope. This means that generally the point of impact of your rifle with the LUCHS-1 attached is very close to the point of impact with just the riflescope. However, because attaching an additional device to the riflescope can alter the vibrations of the rifle and scope during the shot, there may be a change in point of impact with a clip-on attached. This potential change in point of impact can be corrected in the Shot Alignment submenu.

Aligning the LUCHS-1 to your rifle

Make sure that the scope is sighted in properly by shooting a group at your sight-in distance without the LUCHS-1 attached
Attach the LUCHS-1 to an adapter following the adapter manufacturer's instructions and mount it to the scope
Enter the Shot Alignment submenu

There are three alignment profiles so you can use the LUCHS-1 for three separate rifles with the respective alignment profiles.

Toggle through the G1, G2, G3 profiles using the UP and DOWN buttons.
Select the profile you want to use by clicking the MENU button.

Important: Make sure the windage/elevation are both set to zero before shooting. If a lot of adjustment is dialed in, you might miss your target completely.

Shoot a group at your sight-in distance through the LUCHS-1.
Measure the deviation from the point of aim to the point of impact (center of the group)

In the Shot Alignment submenu, you can adjust the point

of impact for elevation and windage and set the minimum rifle scope magnification by following the directions on the screen

Toggle through vertical adjustment/horizontal adjustment/icon display setting by clicking the Menu button

One adjustment step equals 2.76 cm / 100 m . The amount of adjustment from center will be displayed on the screen. The "+" sign indicates a correction of the point of impact up and to the right, the "-" sign indicates a correction of the point of impact down and to the left.

In this submenu you can also adjust the icon display setting for the minimum magnification of your riflescope. You can choose between 2,5x, 3,0x and 4,0x. This setting allows the menu items to be displayed so they are all visible but at the edge of the field of view for typical riflescopes of those magnifications. These magnification values are only guidelines, choose the setting that best matches your rifscope's field of view at your preferred magnification.

Long press the MENU button to save and return.

Important: Make sure to remember which profile is used for which rifle. The selected profile is displayed in the bottom left of the default screen at all times.

Important: After the alignment procedure, confirm your result by shooting a group of at least three shots.

Advanced Settings

14. TROUBLESHOOTING

This overview lists all the problems that can occur when using the unit.

Carry out all recommended checks as described in the table.
If an error occurs that is not listed in the table or if you cannot rectify an error yourself, please contact Liemke Service. You can find the contact details here: https://liemke.shop/de/Reparatur-und-Service/

Malfunction	Possible reason	Correction
The thermal imager cannot be switched on. In the starting process, the LUCHS-1 switches off again after the start logo has been displayed.	Batteries are too weak.	Load the internal battery for half an hour before switching on again. After an initial loading the device can be powered on when loading e.g. with a power bank.
Can't be powered by an external power source.	USB cable is damaged.	Replace USB cable.
The image is blurred, with thin vertical lines or shadows.	Calibration needed.	Calibrate the image.
After calibration, there is a "ghost image" overlayed over the scene.	Calibration mode S was chosen and the lens cap was not closed during calibration.	Perform another calibration with closed lens cap.
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 without sunshine, and especially in rainy conditions, the observed objects cool down to approximately the same temperature, so that the temperature contrast is considerably reduced and the image quality suffers as a result. This characteristic is due to physical reasons and does not represent a defect in the thermal imager.
Taking photos or videos does not work.	20 seconds time after startup has not passed.	Wait 20 seconds after starting the device before taking photos or videos.
Wifi cannot be activated in the menu.	30 seconds after start-up has not passed.	Wait 30 seconds after starting the device before activating Wifi.
Point of impact is not constant.	Thread adapter is not tightened or the clamping force of the adapter is not properly adjusted.	Make sure that thread adapter and the clamping adapter are firmly attached and tightened without play in any direction.
	The parallax adjustment the riflescope is set to close range.	Set the parallax adjustment to 100 m.
	Minimum mounting distance not observed.	Make sure the distance between the bottom of the LUCHS-1 and the barrel is at least 10 mm.
