预防措施
Preventive measures:
当在海拔高度低于1400米的地方使用投影机时,请确保将[高海拔]设定为[关]。
– Please make sure to set the High land off when using the projector at altitudes below 1400 meters, or it may
否则可能会缩短内部组件的寿命或导致功能故障。
shorten the life of internal components or even cause functional failure.
当在海拔高度高于1400米,且低于2700米的地方使用投影机时,请确保将[高海拔]设定为[开]。
– Please make sure to set the High land on when using the projector at altitudes above 1400 meters but below

2700 meters, or it may shorten the life of internal components or even cause functional failure.
请勿在海拔2700米以上的地方安装投影机。
– Never install the projector in a place higher than 2700 meters, or it may shorten the life of internal components
否则可能会缩短内部组件的寿命或导致功能故障。
or even cause functional failure.
(参见"投影机设置菜单"操作说明)。
– Some more detailes about operation guidence, please refer to the projector setup menu.
在高海拔地区使用本投影机时, 请向经销商或授权服务中心咨询相关预防措施
– Please consult the dealer or authorized service center for preventive measures if you want to use the projector
in high altitude area.
关于无铅焊锡(pb Free)
本投影机使用的是应用无铅焊锡的PCB板。
Lead-free solder (Pb Free)
维修时请使用无铅焊锡,防止对全球环境造成污染。
The projector uses the PCB board of lead-free solder.
