摘要
无盘工作系统能否正常工作与网络的性能是否良好密切相关,特别是在底层的结构上,一定要保证工艺,保证质量。在日常的维护工作中要十分注意这些细节。当投影机的投影效果下降,亮度降低,对比度下降时,不仅要检查灯泡使用时限,也要检查PBS镜片的状态,以确保维护完成后获得预期的效果。
The working condition of non-disk system is closely related to the status quo of network properties; good technics and quality of basic structure are important in particular. It is therefore necessary that those details are attended to in daily routine maintenance. When the projector appears low in brightness and contrast electric bulbs should be checked for life span and PBS lens be examined so as to achieve expected results upon completion of maintenance.
