27 MAGIC REMOTE CONTROL
Using the Magic Remote Control
1
Shake the magic remote control lightly when there is no pointer
displayed on the screen. A pointer will be displayed on the
screen.
- The pointer disappears if the remote control is not used for a
certain period of time.
2
When you move the pointer signal transmitter up/down/left/right
while pointing it toward the projector, the pointer moves.
- If the pointer is not working properly, do not move the magic
remote control for about 10 seconds, and then try again.
3
If you press the navigation button while moving the pointer on
the screen, the pointer disappears, and the magic remote control
works as a common remote control.
4
Use within an effective distance of 10 meters. (32.8 feet). Using
the remote control from greater distances or when obstructions
block the sight line may cause malfunctions.
5
Electronic devices nearby may cause communication
interference. Devices such as microwave ovens and wireless
LANs use the same frequency range (2.4 GHz) as the Magic
Remote Control and may cause interference.
6
Take care not to bang it against other hard objects such as
furniture or the floor.
