Хорошее руководство по эксплуатации

Законодательство обязывает продавца передать покупателю, вместе с товаром, руководство по эксплуатации QSC RAVE 160. Отсутствие инструкции либо неправильная информация, переданная потребителю, составляют основание для рекламации в связи с несоответствием устройства с договором. В законодательстве допускается предоставлении руководства в другой, чем бумажная форме, что, в последнее время, часто используется, предоставляя графическую или электронную форму инструкции QSC RAVE 160 или обучающее видео для пользователей. Условием остается четкая и понятная форма.

Что такое руководство?

Слово происходит от латинского "instructio", тоесть привести в порядок. Следовательно в инструкции QSC RAVE 160 можно найти описание этапов поведения. Цель инструкции заключается в облегчении запуска, использования оборудования либо выполнения определенной деятельности. Инструкция является набором информации о предмете/услуге, подсказкой.

К сожалению немного пользователей находит время для чтения инструкций QSC RAVE 160, и хорошая инструкция позволяет не только узнать ряд дополнительных функций приобретенного устройства, но и позволяет избежать возникновения большинства поломок.

Из чего должно состоять идеальное руководство по эксплуатации?

Прежде всего в инструкции QSC RAVE 160 должна находится:
- информация относительно технических данных устройства QSC RAVE 160

- правила обслуживания, настройки и ухода за оборудованием QSC RAVE 160
- знаки безопасности и сертификаты, подтверждающие соответствие стандартам

Почему мы не читаем инструкций?

Как правило из-за нехватки времени и уверенности в отдельных функциональностях приобретенных устройств. К сожалению само подсоединение и запуск QSC RAVE 160 это слишком мало. Инструкция заключает ряд отдельных указаний, касающихся функциональности, принципов безопасности, способов ухода (даже то, какие средства стоит использовать), возможных поломок QSC RAVE 160 и способов решения проблем, возникающих во время использования. И наконец то, в инструкции можно найти адресные данные сайта QSC, в случае отсутствия эффективности предлагаемых решений. Сейчас очень большой популярностью пользуются инструкции в форме интересных анимаций или видео материалов, которое лучше, чем брошюра воспринимаются пользователем. Такой вид инструкции позволяет пользователю просмотреть весь фильм, не пропуская спецификацию и сложные технические описания QSC RAVE 160, как это часто бывает в случае бумажной версии.

Почему стоит читать инструкции?

Прежде всего здесь мы найдем ответы касательно конструкции, возможностей устройства QSC RAVE 160, использования отдельных аксессуаров и ряд информации, позволяющей вполне использовать все функции и упрощения.

После удачной покупки оборудования/устройства стоит посвятить несколько минут для ознакомления с каждой частью инструкции QSC RAVE 160. Сейчас их старательно готовят или переводят, чтобы они были не только понятными для пользователя, но и чтобы выполняли свою основную информационно-поддерживающую функцию.

    3 I. Introduction RAVE Digital Audio Router products provide a means of transporting audio signals over a data network. Using common Fast Ethernet as the physical medium, a RAVE system has a maximum capacity of 64 channels on a 100baseTX network. RAVE transports the audio signals over the network in a 48 kHz 20-bit digital format. Each unit has a f[...]

    4 GLOSSARY Below are some terms used in this manual that RAVE users should be familiar with. AES3 —A technological specification for inter-device conveyance of a dual-channel (stereo) digital audio signal. Also called AES/EBU. Crossover cable —A type of twisted-pair Ethernet patch cable, but somewhat analogous in function to a null modem cable.[...]

    5 Therefore, the CobraNet™ technology used in a RAVE system employs a regulated, deterministic system of packet timing to ensure consistent and reliable transmission without dropouts or glitches. The RAVE devices on a common network will auto- matically negotiate the time slots among them- selves. For efficiency, the sample data from eight audio [...]

    6 Channel routing A RAVE network handles routing in groups of eight audio channels, and each group of eight transmitted on the network makes up one network channel. Each RAVE device handles two network channels—two sent, two received, or one of each. For example, a RAVE 161 unit, with 16 analog audio inputs, represents two transmitted groups, and[...]

    9 Data signals sent over optical fiber don’t degrade as much as they do over copper wiring, and they are immune to induced interference from electromagnetic and RF sources, fluorescent lighting fixtures, etc. Consequently, a Fast Ethernet fiber optic network segment (100baseFX) can be up to 2 kilometers (6560 feet, or 1.24 miles) long, twenty tim[...]

    10 The illustration at right shows a simple 2-node network similar to the one decribed before, except nearly all of the interconnecting UTP cable between the RAVE devices has been replaced by a pair of 100baseTX-to-100baseFX converters and a length of fiber optic cable. This conversion to a fiber optic medium allows the distance between the RAVE un[...]

    11 in that its deterministic nature affords a bit more tolerance of delay than unregulated, non-deterministic network traffic can handle: a network span or diameter of up to 2560 bit periods (with Fast Ethernet, 1 bit period = 10 nanoseconds), or 25.6 microseconds. Unless you are designing very large and complicated RAVE networks, though, you’re [...]

    22 WHAT HAPPENS IF I RUN OUT OF CHANNELS? Network channels automatically drop when available network bandwidth is exhausted. The network channels with the highest address numbers will be the first to be dropped. The “TX Error” indicator will light when a transmitting unit cannot send due to insufficient bandwidth. If this occurs when the networ[...]
