The surface temperature of
projector ascended.
As the high-luminance LED equipped in the projector will generate
heat in long-time use, the projector case will help to dissipate heat
so that its surface temperature will ascend. This will not affect
the performance of projector. Please operate the projector in a
ventilated environment indoor as far as possible.
