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

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

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

Brightness

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 he functions for click are on top, long press in 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

Input Mode Brightness Calibration Color Mode Menu Take Photo Start/Stop Video G1 A

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.

S 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.

WiFi

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

Shot Alignment

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)

0.0 cm/100m ↑ 0.0 cm/100m ← 2.5x/3.0x/4.0x move impact → move impact ← short press: ↑/←/ x long press: save G1 [1111] A

In the Shot Alignment submenu, you can adjust the point

of impact for elevation and windage and set the minimum riflescope 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 riflescope'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

1. Color Mode active/inactive

Color Modes can be selectively deactivated in this submenu.

Choose a color mode by toggling with the UP and DOWN buttons and check/un-check it by clicking the MENU button.
Long press the MENU button to save your settings and return to the menu.

Deactivated color modes will not show up in the Color Mode submenu in the main or when toggling through them with a button so you only have to cycle through the color modes that you find useful.

2. Language

Choose between English or German menu language

3. Defective Pixel Repair

If during use there are pixels that are permanently bright ("hot pixels") and that do not disappear after using the calibration function, you can correct these pixels by performing the Defective Pixel repair function.

Attention: Close the lens cap before performing this operation.

Confirm (Y) by clicking the MENU button.

A countdown will appear and then a green tick mark to confirm successful Pixel Repair.

4. Restore Factory Settings

Confirm (Y) by clicking the MENU button to reset the device to the default settings.

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 calibrat-iong.	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 con-stant.	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 adjust-menton 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.
