If the pens do not work, try the following
solutions:
-
The pens
go into standby mode if you forget to turn them off. Touch the tip
of the pen to activate it.
-
Make sure
you are not covering the black section near the tip of the
pen.
-
Make sure
nothing is blocking the signal between the pen and the interactive
pen receiver on the projector.
-
Try
holding the pen at a different angle so that your hand is not
blocking the signal.
-
Make sure
the cable cover is in place to keep cables from blocking the
signal.
-
Make sure
the pen battery has enough power. Try replacing the battery.
-
If you are
projecting from a computer, make sure the USB cable is connected to
the computer and projector.
-
Dim the
room lights and turn off any fluorescent lights. Make sure the
projection surface and pen receiver are not in direct sunlight or
other sources of bright lighting.
-
If the pen
tip is worn out or damaged, you may need to replace it.
-
Make sure
the pen receiver on the projector is clean and free from dust.
-
Make sure
there is no interference from infrared remote controls or infrared
microphones.
-
Make sure
the USB Type-B option on the
Extended menu is set to Easy Interactive
Function or USB Display/Easy
Interactive Function.
-
Make sure
the Use Source option on the
Extended menu is set to the correct source.
-
Make sure
you have calibrated the system. Try recalibrating.
Note: You cannot
use both pens at the same time with the built-in toolbar.
