I. Proc\u00e9dure de fonctionnement correcte\u00a0:<\/em><\/span><\/h4>\n

Allumez d'abord la source du signal, puis l'\u00e9cran ; \u00e9teignez d'abord l'\u00e9cran, puis la source du signal :<\/strong><\/p>\n

\u2460 Lors de la mise sous tension de la source de signal de l'ordinateur de contr\u00f4le, assurez-vous que le voyant est correctement allum\u00e9 et que l'interrupteur principal de l'afficheur LED est \u00e9galement activ\u00e9. V\u00e9rifiez que l'ordinateur \u00e9met un signal correct avant d'allumer l'afficheur.<\/em><\/p>\n

2. Coupez l'alimentation principale de l'\u00e9cran LED. Vous devez \u00e9galement \u00e9teindre l'ordinateur de contr\u00f4le. Ne d\u00e9branchez pas l'alimentation directement et n'effectuez aucune op\u00e9ration inverse.<\/em><\/p>\n

\u2462 L'intervalle entre l'allumage et l'extinction de l'\u00e9cran doit \u00eatre sup\u00e9rieur \u00e0 5 minutes. \u00c9vitez les allumages et extinctions fr\u00e9quents afin de pr\u00e9venir les surtensions.<\/em><\/p>\n

II. Points cl\u00e9s pour l'entretien courant\u00a0:<\/em><\/span><\/h4>\n

1. Exigences relatives \u00e0 l'environnement d'exploitation\u00a0:<\/strong><\/p>\n

\u2460 Temp\u00e9rature de fonctionnement\u00a0: -20\u00a0\u00b0C \u00e0 50\u00a0\u00b0C. Humidit\u00e9 de fonctionnement\u00a0: 10\u00a0% \u00e0 90\u00a0% HR (sans condensation). Temp\u00e9rature de stockage\u00a0: 10\u00a0\u00b0C \u00e0 40\u00a0\u00b0C. Humidit\u00e9 de stockage\u00a0: \u2264\u00a060\u00a0% HR.<\/em><\/p>\n

\"\"<\/p>\n

2. Consid\u00e9rations environnementales :<\/strong><\/p>\n

\u2460 Assurez-vous d'une ventilation ad\u00e9quate autour de l'\u00e9cran et que les orifices de dissipation de chaleur ne soient pas obstru\u00e9s.<\/em><\/p>\n

\u2461\u00c9viter l\u2019utilisation dans des environnements caract\u00e9ris\u00e9s par des temp\u00e9ratures \u00e9lev\u00e9es, une humidit\u00e9 \u00e9lev\u00e9e, des acides ou des bases forts, ou des embruns sal\u00e9s.<\/em><\/p>\n

\u2462 Toute infiltration d'eau dans l'\u00e9cran est strictement interdite ; emp\u00eacher l'entr\u00e9e de substances conductrices, telles que de la limaille de fer ou des objets m\u00e9talliques.<\/em><\/p>\n

3. Utiliser la gestion du temps :<\/strong><\/p>\n

\u2460 Il est recommand\u00e9 d'\u00e9teindre l'\u00e9cran pendant au moins deux heures chaque jour pour se reposer.<\/em><\/p>\n

\u2461 Pendant la saison des pluies de prunes ou par temps humide, allumez l'\u00e9cran pendant 1 \u00e0 2 heures au moins une fois par semaine pour d\u00e9shumidifier.<\/em><\/p>\n

\u2462 L'affichage d'images statiques, telles que des logos ou du texte, pendant des p\u00e9riodes prolong\u00e9es peut entra\u00eener un marquage de l'\u00e9cran ou une r\u00e9manence d'image ; il est recommand\u00e9 d'utiliser du contenu dynamique ou un \u00e9conomiseur d'\u00e9cran.<\/em><\/p>\n

\"\"<\/p>\n

3. M\u00e9thode de nettoyage :<\/strong><\/p>\n

\u2460 Nettoyez d\u00e9licatement la poussi\u00e8re de la surface de l'\u00e9cran \u00e0 l'aide d'une brosse \u00e0 poils souples ou d'un aspirateur. N'utilisez pas de chiffons humides ni de produits nettoyants liquides.<\/em><\/p>\n

\u2461 Les taches tenaces peuvent \u00eatre nettoy\u00e9es d\u00e9licatement avec de l'alcool. L'utilisation de substances corrosives est interdite.<\/em><\/p>\n

\u2462 Pour l'int\u00e9rieur, les coins et les bords, utilisez un chiffon doux non pelucheux. Ne rincez pas directement \u00e0 l'eau.<\/em><\/p>\n

4. \u00c9l\u00e9ments d'inspection p\u00e9riodique :<\/strong><\/p>\n

\u2460V\u00e9rifiez si les c\u00e2bles d'alimentation et les c\u00e2bles de signal sont desserr\u00e9s ou us\u00e9s.<\/em><\/p>\n

\u2461 Uniformit\u00e9 de la luminosit\u00e9 et coh\u00e9rence des couleurs ; calibrer si n\u00e9cessaire.<\/em><\/p>\n

\u2462La temp\u00e9rature et l'humidit\u00e9 sont-elles dans la plage normale, et le ventilateur de refroidissement fonctionne-t-il correctement\u00a0?<\/em><\/p>\n

\u2463V\u00e9rifiez si le bo\u00eetier de l'\u00e9cran est d\u00e9form\u00e9 ou fissur\u00e9, et si les composants de connexion sont bien fix\u00e9s.<\/em><\/p>\n

III. Pr\u00e9cautions pour le stockage \u00e0 long terme\u00a0:<\/em><\/span><\/h4>\n

\u2460Nettoyez soigneusement l'\u00e9cran avant de le ranger.<\/em><\/p>\n

\u2461 Conserver dans un environnement \u00e0 temp\u00e9rature et humidit\u00e9 contr\u00f4l\u00e9es (10\u201340\u00b0C, \u226460% HR).<\/em><\/p>\n

\u2462\u00c9vitez la lumi\u00e8re directe du soleil et les sources de lumi\u00e8re intense.<\/em><\/p>\n

\u2463 Veuillez emballer soigneusement en utilisant l'emballage d'origine ou une valise de transport, \u00e9vitez absolument de placer des objets lourds dessus.<\/em><\/p>\n

\u2464Mettre en \u0153uvre des mesures d\u2019\u00e9tanch\u00e9it\u00e9 \u00e0 l\u2019humidit\u00e9, telles que le dessiccant de gel de silice.<\/em><\/p>\n

\u2465 Inspectez r\u00e9guli\u00e8rement les conditions de stockage.<\/em><\/p>","protected":false},"excerpt":{"rendered":"
