Vivitek Qumi Q3 Plus - Manual (Page 47)

41
Qumi does not use a typical light source. It uses a set of Light Emitting Diodes (LED) to
illuminate and project images. LED’s have a greater lifespan than conventional lamps.
Qumi LED’s are estimated to last for approximately 30,000 hours. The lifespan of the
LED depends on factors such as brightness, usage, environmental conditions. LED
brightness can decrease over time. The LED module is not replaceable.
10. Why do I need to re-adjust the focus on my Qumi after it’s powered up?
For the best picture quality, adjustment of the remote controller’s Zoom-In (+)/Zoom-Out
(-) Keys may be necessary once the operational temperature has been met.
11. I’ve lost my remote. Where can I get a replacement?
Contact your Reseller or Vivitek Service via www.vivitekcorp.com (select region) to
obtain a replacement remote (Charges may be applied).
