Richtige Gebrauchsanleitung

Die Vorschriften verpflichten den Verkäufer zur Übertragung der Gebrauchsanleitung Metrologic Instruments IS4921 an den Erwerber, zusammen mit der Ware. Eine fehlende Anleitung oder falsche Informationen, die dem Verbraucher übertragen werden, bilden eine Grundlage für eine Reklamation aufgrund Unstimmigkeit des Geräts mit dem Vertrag. Rechtsmäßig lässt man das Anfügen einer Gebrauchsanleitung in anderer Form als Papierform zu, was letztens sehr oft genutzt wird, indem man eine grafische oder elektronische Anleitung von Metrologic Instruments IS4921, sowie Anleitungsvideos für Nutzer beifügt. Die Bedingung ist, dass ihre Form leserlich und verständlich ist.

Was ist eine Gebrauchsanleitung?

Das Wort kommt vom lateinischen „instructio”, d.h. ordnen. Demnach kann man in der Anleitung Metrologic Instruments IS4921 die Beschreibung der Etappen der Vorgehensweisen finden. Das Ziel der Anleitung ist die Belehrung, Vereinfachung des Starts, der Nutzung des Geräts oder auch der Ausführung bestimmter Tätigkeiten. Die Anleitung ist eine Sammlung von Informationen über ein Gegenstand/eine Dienstleistung, ein Hinweis.

Leider widmen nicht viele Nutzer ihre Zeit der Gebrauchsanleitung Metrologic Instruments IS4921. Eine gute Gebrauchsanleitung erlaubt nicht nur eine Reihe zusätzlicher Funktionen des gekauften Geräts kennenzulernen, sondern hilft dabei viele Fehler zu vermeiden.

Was sollte also eine ideale Gebrauchsanleitung beinhalten?

Die Gebrauchsanleitung Metrologic Instruments IS4921 sollte vor allem folgendes enthalten:
- Informationen über technische Daten des Geräts Metrologic Instruments IS4921
- Den Namen des Produzenten und das Produktionsjahr des Geräts Metrologic Instruments IS4921
- Grundsätze der Bedienung, Regulierung und Wartung des Geräts Metrologic Instruments IS4921
- Sicherheitszeichen und Zertifikate, die die Übereinstimmung mit entsprechenden Normen bestätigen

Warum lesen wir keine Gebrauchsanleitungen?

Der Grund dafür ist die fehlende Zeit und die Sicherheit, was die bestimmten Funktionen der gekauften Geräte angeht. Leider ist das Anschließen und Starten von Metrologic Instruments IS4921 zu wenig. Eine Anleitung beinhaltet eine Reihe von Hinweisen bezüglich bestimmter Funktionen, Sicherheitsgrundsätze, Wartungsarten (sogar das, welche Mittel man benutzen sollte), eventueller Fehler von Metrologic Instruments IS4921 und Lösungsarten für Probleme, die während der Nutzung auftreten könnten. Immerhin kann man in der Gebrauchsanleitung die Kontaktnummer zum Service Metrologic Instruments finden, wenn die vorgeschlagenen Lösungen nicht wirksam sind. Aktuell erfreuen sich Anleitungen in Form von interessanten Animationen oder Videoanleitungen an Popularität, die den Nutzer besser ansprechen als eine Broschüre. Diese Art von Anleitung gibt garantiert, dass der Nutzer sich das ganze Video anschaut, ohne die spezifizierten und komplizierten technischen Beschreibungen von Metrologic Instruments IS4921 zu überspringen, wie es bei der Papierform passiert.

Warum sollte man Gebrauchsanleitungen lesen?

In der Gebrauchsanleitung finden wir vor allem die Antwort über den Bau sowie die Möglichkeiten des Geräts Metrologic Instruments IS4921, über die Nutzung bestimmter Accessoires und eine Reihe von Informationen, die erlauben, jegliche Funktionen und Bequemlichkeiten zu nutzen.

Nach dem gelungenen Kauf des Geräts, sollte man einige Zeit für das Kennenlernen jedes Teils der Anleitung von Metrologic Instruments IS4921 widmen. Aktuell sind sie genau vorbereitet oder übersetzt, damit sie nicht nur verständlich für die Nutzer sind, aber auch ihre grundliegende Hilfs-Informations-Funktion erfüllen.

    18 Since many host systems and applications have unique fo rmats and protocol requirements, the decode engin e supports a wide range of configurable features. These featu res may be selected by scanning a corresponding configuration bar code from the MetroSelect Single-Line Configuration Guide or Area Imaging Bar code Supplemental Configuration Gui[...]

    19 The nTrig signal not only wakes the engine up, but also immediately a ctivates and turns the engine into the Operating Mode. Either nWake or nTrig signals can be used to restart the TTL RS232 scanning engine when the engine is in Power-down Mode, which is indicated by the asserted (high) PWRDWN signal. The PWDWN pin is used to indicate when the [...]

  • Seite 26

    20 Power Mode Descriptions Boot Mode The engine is booting up. PWRDWN Pin State: Asserted (HIGH). Transition to Boot Mode: • The TTL RS232 engine is turned to Boot Mode from Power Down Mode when the power is applied AND upon reception of the nTrig or nWake signals. • The USB engine enters Boot Mode upon completion of USB enumeration. • The en[...]

  • Seite 27

    21 Sleep Mode The engine is sleeping, but is fully powered. The CPU is in sleep mode. The image sensor is in standby mode, the wakeup from the Sleep Mode requires the image sensor reprogramming (which is done automatically in the engine software). PWRDWN Pin State: De-asserted (LOW). Transition to Sleep Mode: • The engine is turned to Sleep Mode [...]

  • Seite 28

    22 Serial Configuration The IS4920 series can be configured by scanning configuration bar code s † or by serial commands sent from the host device. With serial configuration, each comm and sent to the engine is the ASCII representation of each numeral in the configuration bar code (see Figure 19). The entire numeric string is framed with an ASCII[...]

  • Seite 31

    25 The TTL version of the decode engine does not have an on b oard microcontroller to control the power to the decode platform and imaging engine. As such, the TTL version can only enter Boot Mode in response to signals from the host (nTrig or nWake). When VIN is initially applied with the nWake and nTrig signals held high, the unit will be in the [...]

  • Seite 32

    26 Notes: In Figure 21 , the nGoodRead, nBeeper, and PWRDWN signals are high while in the Power Down Mode. The RTS Signal will be high in Power Down Mode regardless of the RTS polarity software configuration. Also, the RTS signal may have the incorrect polarity when the device first enters Boot Mode (Figure 23) or right before the unit enters Power[...]

    27 Decode Timing Engine image acquisition or decoding can occur from either the Idle Mode or the Sleep Mode. The process is initiated by asserting the nTrig signal (or serial command when in the Idle Mode). Once the trigger signal is received, the image sensor is reset and image acquisition begins. During image acquisition, the illumination LEDs ar[...]
