Important Information Regarding SD Card Usage

In rare cases, technical issues may occur when using UHS-I cards. To generally avoid these errors and ensure optimal camera performance, Leica recommends using UHS-II cards.

Firmware Updates

Leica continuously develops and optimizes cameras. As many camera functions are software-controlled, enhancements and improvements can be installed. Leica occasionally offers firmware updates for download from their website. Registered cameras will be notified of the latest updates. Leica FOTOS users will also be automatically informed.

Firmware updates can be installed in two ways:

• Conveniently via the Leica FOTOS app
• Directly from the camera menu

Checking the Installed Firmware Version

• From the main menu, select Camera Information.
• Next to the Camera Firmware Version menu item, the current firmware version is displayed.

Further information on registration, firmware updates, or downloads for your camera, including changes and additions to the manual, can be found in the "Customer Area" at: club.leica-camera.com

Performing a Firmware Update

Warning: If a firmware update is interrupted, severe permanent damage to your equipment may occur!

Therefore, pay close attention to the following information during the firmware update:

• Do not turn off the camera!
• Do not remove the memory card!
• Do not remove the battery!
• Do not detach the lens!

Notes

• If the battery is not fully charged, a warning message will appear. In this case, charge the battery first and repeat the procedure.
• The Camera Information submenu contains approval marks and numbers for additional devices and specific countries.

Preparation

• Charge and insert the battery.
• If present, remove all firmware files from the memory card.
• It is recommended to back up all images on the memory card, then format the memory card in the camera. (Caution: Data will be lost! Formatting the memory card erases all available data.)
• Files in internal memory should also be backed up as a precautionary measure.
• Download the latest firmware.
• Save to memory card: Firmware files must be saved in the top-level folder on the memory card (not in a subfolder).
• Insert the memory card into the camera.
• Turn on the camera.

Updating Camera Firmware

For M11 / M11-P / M11 Monochrom

1. Perform preparation steps.
2. From the main menu, select Camera Information.
3. Select Camera Firmware Version.
4. Select Firmware Update.
5. A prompt with update information will appear. Check version information.
6. Select Yes.
7. A prompt "Do you want to save profiles on SD card?" will appear.
8. Select Yes/No.
9. The update starts automatically.
10. During the process, the status LED will blink.
11. After the update is successfully completed, a corresponding message will appear, and the camera will restart.

Notes

• It is recommended to reset the camera to factory settings after the update.
• After resetting, the date & time and language must be set again. Corresponding prompts will appear.

For M11-D

1. Perform preparation steps.
2. Press and hold the function button.
3. Turn on the camera.
4. During the update, the status LED and the automatic timer LED will blink red, and "UP" will appear in the viewfinder.

Formatting Storage Locations

It is advisable to format storage locations occasionally, as residual data (image-related information) may consume memory capacity. The inserted memory card and internal memory can be formatted separately. Please note the following:

• Do not turn off the camera while the process is running.
• If the memory card is formatted, all available data on it will be erased. Formatting cannot be prevented by marking images with write protection.
• Therefore, all images should be regularly transferred to secure mass storage, such as a computer's hard disk.

Internal Memory Secure Erase

Internal memory can be formatted to erase residual data accumulated over time or to quickly free up memory.

1. From the main menu, select Storage Management.
2. Select Format Storage.
3. Select Format internal memory (secure).
4. Confirm the operation.

Notes

• Normal formatting only deletes directories, making existing files inaccessible. With appropriate software, data can be recovered. Data is permanently erased only when overwritten by newly saved data.
• To thoroughly and permanently erase all images, image fragments, and personal data, the Format internal memory (secure) erase process must be selected. This process may take up to 75 minutes.
• If a memory card is formatted on another device, such as a computer, you must reformat the memory card in the camera.
• For the Leica M11-D, the secure erase process can only be performed using the Leica FOTOS app.
