Operating the LASER pointer
The LASER Pointer is a presentation aid
for professionals. It emits red colored
light when you press it and the indicator
lights up red.
The laser beam is visible. It is necessary to
press and hold LASER for continuous
output.
Do not look into the laser light
window or shine the laser light beam on
yourself or others. See the warning messages
on the back of the remote control prior to
using it.
The laser pointer is not a toy. Parents should be
mindful of the dangers of laser energy and keep this
remote control out of the reach of children.
Remote control effective range
Infra-Red (IR) remote control sensors are located on
the front and the back of the projector. The remote
control must be held at an angle within 30 degrees
perpendicular to the projector's IR remote control
sensors to function correctly. The distance between the
remote control and the sensors should not exceed 8
meters (~ 26 feet).
Make sure that there are no obstacles between the
remote control and the IR sensors on the projector that
might obstruct the infra-red beam.
