Q: The projector is very slow when toggling between different files?
A: The projector is run by a highly sophisticated CPU for all decoding and projecting works. When you experience the slow speed, it may be because a lot of “instructions” / “actions” were received during a short moment … in this case, please state for a while rather than keep adding instructions by pushing buttons, or simply reset by turn off the machine and restart.

Q: What happens if I accidentally plug in a 3.5mm plug in the wrong socket?
A: You should pay careful attention and avoid the wrong plugging behaviour to happen. On the other hand, we have certain protections on this. The DC jack hole is protected and only the appropriate power plug can be inserted in, while the AV jack are mechanically not able to be plugged in (unless using over-force) On the other hand, the DC power plug is able to be plugged into the other jack, namely, the AV-in and the headset jack. However, it would not have any performance or charging when wrongly plug in, but of course, still need to be unplugging immediately for safety reason.
Q: How do I adjust audio level when watching a video film from a PS3/iPhone/iPOD/....
A: The audio level from multimedia sources connected to K1511´s AV IN port or to the USB Port may be controlled from the source (provided the media source supports audio out volume control). External speakers, headsets, amplifiers etc. that are connected to the Audio Out usually have volume control functions.

A: Connect the PC to the projector, and have the “USB storage” selected, and from the PC screen, you would find out the projector internal memory and SD-card, if inserted onto the K1511, to be as removable HD, and content can be moving / copying from PC to these HD’s, or vice versa.
Q: How much free memory for content is available in the projector?
A: The standard internal flash memory is minimum 1GB.
Q: Can I use a 12V car charger?
