Un buon manuale d’uso

Le regole impongono al rivenditore l'obbligo di fornire all'acquirente, insieme alle merci, il manuale d’uso Leisure Time LX20. La mancanza del manuale d’uso o le informazioni errate fornite al consumatore sono la base di una denuncia in caso di inosservanza del dispositivo con il contratto. Secondo la legge, l’inclusione del manuale d’uso in una forma diversa da quella cartacea è permessa, che viene spesso utilizzato recentemente, includendo una forma grafica o elettronica Leisure Time LX20 o video didattici per gli utenti. La condizione è il suo carattere leggibile e comprensibile.

Che cosa è il manuale d’uso?

La parola deriva dal latino "instructio", cioè organizzare. Così, il manuale d’uso Leisure Time LX20 descrive le fasi del procedimento. Lo scopo del manuale d’uso è istruire, facilitare lo avviamento, l'uso di attrezzature o l’esecuzione di determinate azioni. Il manuale è una raccolta di informazioni sull'oggetto/servizio, un suggerimento.

- informazioni sui dati tecnici del dispositivo Leisure Time LX20
- nome del fabbricante e anno di fabbricazione Leisure Time LX20
- istruzioni per l'uso, la regolazione e la manutenzione delle attrezzature Leisure Time LX20
- segnaletica di sicurezza e certificati che confermano la conformità con le norme pertinenti

Perché non leggiamo i manuali d’uso?

Generalmente questo è dovuto alla mancanza di tempo e certezza per quanto riguarda la funzionalità specifica delle attrezzature acquistate. Purtroppo, la connessione e l’avvio Leisure Time LX20 non sono sufficienti. Questo manuale contiene una serie di linee guida per funzionalità specifiche, la sicurezza, metodi di manutenzione (anche i mezzi che dovrebbero essere usati), eventuali difetti Leisure Time LX20 e modi per risolvere i problemi più comuni durante l'uso. Infine, il manuale contiene le coordinate del servizio Leisure Time in assenza dell'efficacia delle soluzioni proposte. Attualmente, i manuali d’uso sotto forma di animazioni interessanti e video didattici che sono migliori che la brochure suscitano un interesse considerevole. Questo tipo di manuale permette all'utente di visualizzare tutto il video didattico senza saltare le specifiche e complicate descrizioni tecniche Leisure Time LX20, come nel caso della versione cartacea.

Perché leggere il manuale d’uso?

Prima di tutto, contiene la risposta sulla struttura, le possibilità del dispositivo Leisure Time LX20, l'uso di vari accessori ed una serie di informazioni per sfruttare totalmente tutte le caratteristiche e servizi.

Dopo l'acquisto di successo di attrezzature/dispositivo, prendere un momento per familiarizzare con tutte le parti del manuale d'uso Leisure Time LX20. Attualmente, sono preparati con cura e tradotti per essere comprensibili non solo per gli utenti, ma per svolgere la loro funzione di base di informazioni e di aiuto.

    In the Schmidt-Cassegrain design of the Meade 8", 10", and 12" models, light enters from the right, passes through a thin lens with 2-sided aspheric correction ("correcting plate"), proceeds to a spherical primary mirror, and then to a convex aspheric secondary mirror. The convex secondary mirror multiplies the effective fo[...]

    ¬ WARNING! ¬ Never use the LX200 telescope to look at the Sun! Looking at or near the Sun will cause instant and irreversible damage to your eye. Eye damage is often painless, so there is no warning to the observer that damage has occurred until it is too late. Do not point the telescope or its viewfinder at or near the Sun. Do not look through t[...]

    MAGNIFICATION AND FIELD OF VIEW 1. Magnification The magnification (power) of the telescope depends on two characteristics: the focal length of the main telescope and the focal length of the eyepiece used during a particular observation. For example, the focal length of the LX200 7" f/15 telescope is fixed at 2670mm; the focal length of the 8&[...]
