Хорошее руководство по эксплуатации
Законодательство обязывает продавца передать покупателю, вместе с товаром, руководство по эксплуатации JBL GTS100. 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 JBL GTS100 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 JBL GTS100 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 JBL GTS100, 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 JBL GTS100 должна находится:
- информация относительно технических данных устройства JBL GTS100
- название производителя и год производства оборудования JBL GTS100
- правила обслуживания, настройки и ухода за оборудованием JBL GTS100
- 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 JBL GTS100 это слишком мало. Инструкция заключает ряд отдельных указаний, касающихся функциональности, принципов безопасности, способов ухода (даже то, какие средства стоит использовать), возможных поломок JBL GTS100 и способов решения проблем, возникающих во время использования. И наконец то, в инструкции можно найти адресные данные сайта JBL, 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 JBL GTS100, как это часто бывает в случае бумажной версии.
Почему стоит читать инструкции?
Прежде всего здесь мы найдем ответы касательно конструкции, возможностей устройства JBL GTS100, 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 JBL GTS100. Сейчас их старательно готовят или переводят, чтобы они были не только понятными для пользователя, но и чтобы выполняли свою основную информационно-поддерживающую функцию.

System Design Using the GTS100 Speakers When used in the non-bridged mode, the GTS100 can easily drive 2 ohm speaker loads. When only one speaker is connected to each channel, virtually any common speaker may be used. When two speakers are connected in parallel to a given channel, each speaker must have a minimum impedance of at least 4 ohms to ens[...]

7 controls (Volume, Balance, Bass, Treble) may be connected to the pre- amp-level inputs at the same time as a powered radio/tape unit is connected to the speaker-level inputs.

9 Installation Precautions Before beginning the installation of the amplifier, read the following precautions carefully. Failure to heed these warn- ings could result in personal injury or damage to property . • The GTS 100 should be installed only in vehicles that have 12-volt negative ground electrical systems. Connection to other types of elec[...]

• The GTS100 must be mounted in a place where air can circulate around the fins on the chassis. Good air circulation around the amplifier will make it operate at lower tempera- tures and reduce the chance of the thermal protection circuits being trig- gered. The installation positions that provide the most efficient air circula- tion around the a[...]

Mounting Instructions Place the amplifier in the installation location. Use a pen or pencil to mark the four mounting screw hole locations. Set the amplifier aside and drill the holes for the mounting screws.

and 16 volts. Check that the power wires are not reversed. If the GTS100 is operated at very high power levels in a high ambient tempera- ture situation, the unit may not be able to radiate all the heat generated by such operation.

the amplifiers and signal processors are all grounded to the same point on the chassis. Usually the head unit does not need to be grounded to the same point as the rest of the system, but in some instances grounding the head unit to the same point will also help.
