Eiki LC-X2U Owner's Instruction Manual page 24

This remote control unit is not only able to operate the projector but also usable as a wireless mouse for a
PC. One pointing pad and two click buttons are used for wireless mouse operation. Wireless mouse is
usable when PC mouse pointer is displayed on the screen. When the menu or indicator of the projector is
displayed on the screen instead of the PC mouse
pointer, the wireless mouse cannot be used.
NOTE: To use the unit as a PC wireless mouse,
connect the projector to the PC with the
attached cable. Signals from the projector are
transmitted to the PC, enabling the remote
control unit of the projector to be used as a
PC wireless mouse. (Refer to "CONNECTING
THE PROJECTOR" in pages 14to 19 for the
connection.)
LASER POINTER
This remote control emits a laser beam light as the Laser Pointer
from the Laser Light Window. When the LASER POINTER
button is pressed, laser light goes on: when the button is
released, light goes off. Laser light is emitted with the RED light
which tells the laser beam being emitted. The laser emitted is a
class II laser; therefore, do not look into the laser light window or
shine the laser beam on yourself or other people. The three
marks to the right are the caution labels for the laser beam.
CAUTION-use of controls or adjustments or performance of
procedures other than those specified herein-may result
hazardous radiation exposure.
