Un buon manuale d’uso

Le regole impongono al rivenditore l'obbligo di fornire all'acquirente, insieme alle merci, il manuale d’uso Cisco Systems IOS XR. 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 Cisco Systems IOS XR 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 Cisco Systems IOS XR 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.

Purtroppo, pochi utenti prendono il tempo di leggere il manuale d’uso, e un buono manuale non solo permette di conoscere una serie di funzionalità aggiuntive del dispositivo acquistato, ma anche evitare la maggioranza dei guasti.

Quindi cosa dovrebbe contenere il manuale perfetto?

Innanzitutto, il manuale d’uso Cisco Systems IOS XR dovrebbe contenere:
- informazioni sui dati tecnici del dispositivo Cisco Systems IOS XR
- nome del fabbricante e anno di fabbricazione Cisco Systems IOS XR
- istruzioni per l'uso, la regolazione e la manutenzione delle attrezzature Cisco Systems IOS XR
- 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 Cisco Systems IOS XR 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 Cisco Systems IOS XR e modi per risolvere i problemi più comuni durante l'uso. Infine, il manuale contiene le coordinate del servizio Cisco Systems 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 Cisco Systems IOS XR, come nel caso della versione cartacea.

Perché leggere il manuale d’uso?

Prima di tutto, contiene la risposta sulla struttura, le possibilità del dispositivo Cisco Systems IOS XR, 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 Cisco Systems IOS XR. 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.
