Leica M10 and M11 hidden service menu, Digi Mart USA News: Leica users have recently discovered a hidden service menu on the Leica M (Typ 240), Leica M10 and Leica M11, as well as all variants of these model lines. The menu can be opened with a specific button combination and shows the remaining battery capacity and the total number of photos taken, information that is relevant to buyers of used cameras.
Some functions within the menu, however, can cause serious problems. According to users reporting on Reddit, the displays on some cameras no longer turn on after options in the service menu have been changed.
The source reports that Leica was contacted about the issue and advises against using the service menu without appropriate technical knowledge.
In a statement translated from German, Leica said that access to internal service menus by end users is not part of the cameras’ standard operating concept. The company said these menus are intended for technical diagnostic and servicing purposes and recommended that users do not access them or make changes on their own, warning that changes to internal settings can impair the proper functioning of the camera.
Leica also said battery capacity information is not shown in the regular menu because the user interface is meant to be kept as uncluttered as possible. The company denied that the Leica M10’s hardware supports a touchscreen, explaining that the diagnostic functions exist because the Leica M10 and M10-P share a common software architecture and therefore use the same service menu.
The service menu remains accessible with the relevant button combination for now, but Leica said this could change following a future software update. The company stated that it reserves the right to modify access to these functions or protect them with additional safeguards, citing the reliable operation of its cameras and proper technical diagnostics as priorities.
