In the speaker amp TAS5717, Band division DRC function is embedded. By this function, the dynamic
range is compressed and increase the average acoustic pressure. With the thin chassis structure, the
sound tends to be stood out. However, by this function, such sound can be decreased.

Passive Pen
•
The Touch Panel is without “antireflection sheet”, therefore it is not so easy to scratch.
•
Aluminum Pen Hardness H2!
Sharp must put „MADE in KOREA“ on
the pen due to some US regulation.
Part Code: CPENP1002MP31

The tip of the pen have a specified
capacity and special size which

Current passive stylus pen cannot support the hover function
and the passive stylus pen is not the digitizer type.
(Current passive stylus pen cannot be certified the pen digitizer function of Windows8 )
Pen with hover function = Digitizer pen

Note:
If the digitizer pen is
connected, then the pen
symbol change in the OSD.
