DOSSIER 01 / READ SOURCES, CLARIFY CONDITIONS
The Samsung OM55B example shows which specifications to confirm before ordering. First compare the product page and manual. Then check shop-window glass, viewing position, ventilation and failure behavior for the installation.
Readability
Mounting
Failure handling
01 / BOUNDARIES IN THE SCHEMATIC
The diagram shows the view through shop-window glass, air around the display and service access. Choose a check to highlight the relevant location.
Viewers look through the shop-window glass at the display. Reflections, viewing angle, text size and sunglasses affect whether they can read prices. The display’s brightness figure alone does not establish readability from the queue.
Next check: display the planned prices and text. Record the viewing position, time of day and information that can actually be read.
Glass separates inside from outside; it does not replace thermal planning. Establish conditions in the installation space and obtain the matching model manual. A DWD annual mean temperature does not prove these conditions.
Next check: confirm mounting orientation, ventilation paths and expected temperatures with the responsible specialist and the model manual.
24/7 describes the display’s stated duty cycle. It does not answer who stops stale prices, detects a blank display or organizes service in the store.
Next check: test fallback content and restart in the pilot. Assign responsibility for faults and confirm how the display can be reached for service.
Check readability, permitted mounting and failure handling separately. A photo may show readable prices but does not establish an acceptable temperature in the installation space. Also test fallback content and restart with the planned player.
02 / SAMSUNG / OM55B / PRODUCT PAGES
Samsung OM55B: compare the model code, luminance, duty cycle and temperature range on the German and UK product pages.
WEB-DE / MANUFACTURER CLAIM
From the German product page, Manufacturer specifications for this model code. These figures and the protection claim do not jointly approve an installation site.

WEB-UK / RECORD THE DISCREPANCY
The English UK page shows LH55OMBEBGBXEN and 55 inches. Two paragraphs of the product description instead name OM46B. This is a wording discrepancy observed on the check date; it does not establish different supplied hardware.
Check question: which statements and current EU manual apply to the complete model code actually offered? Do not silently pick the more favorable wording.

The official support page lists a multilingual EU manual package with a modification date of 30 March 2026 (BN81-22087B-04). Obtain the version matching your equipment and installation before applying particular clearances or installation limits.

03 / SUNLIGHT, GLASS AND DEVICE CONDITIONS
The arithmetic mean of annual DWD area values for Brandenburg/Berlin is 1740.8 sunshine hours per year for 1991–2020. It describes a regional series. It does not show when sunlight reaches your shop-window glass or how warm the air around the installed display becomes. Do not compare it to a model’s 0–40 °C range as though the two measured the same thing.
Record orientation, shade and opening hours. Plan relevant times and seasonal sun positions for the actual viewing point; a winter visit does not automatically cover summer conditions.
An unheated recess, an entrance door and an air-conditioned shop floor are different conditions. Clarify local humidity, temperature patterns and service access with the relevant professionals. No generic winter or coastal approval.
Regional means do not replace site measurements.
04 / YOUR INPUTS, YOUR OPEN QUESTIONS
Record the site and the status of your evidence. This record does not verify files or grant approval. Inputs stay local. Language switching and brief handoff temporarily use session storage; persistent saving happens only when you choose it.
LOCAL DRAFT / NOT APPROVAL
The brief asks before adding questions to your existing notes. Project fields and saved state are retained.
