6.5.28 Stylus

The stylus dialogue allows you to calibrate the touch screen of the PL3000, and set the double tap interval.

There is a simple method to determine how accurately your PL3000’s touch screen is calibrated. Close all

programs so that only the desktop is visible. Then tap and hold the stylus to the screen in an area of the

desktop where there are no icons or any other controls. Move the stylus so that the selection box becomes

visible. You can tell the accuracy of the calibration by how close the corner of the selection box is to the

tip of the stylus pen. If the corner of the selection box is above the pen tip, you will probably experience

difﬁ culties in selecting the taskbar at the bottom of the screen. If the selection box is a millimetre or two

below the pens tip it does not require recalibration, it might actually help a bit when accessing the taskbar.

The sensitivity of the touch screen is also controllable, but not in this dialogue. See the chapter “6.5.24

Touch screen” for the sensitivity setting .

6.5.29 System

The system dialogue allows you to view system details such as operating system version, processor type

and amount of memory installed. You can also set the name of the device. The name is used, among other

programs, by ActiveSync to recognise the device. The most important setting in this dialogue is the memory

division dialogue. Of the RAM present in a typical PL3000 half is by default used as execution memory for

programs, the other half is used to store ﬁ les and installed programs. All software installed onto the unit

after the production reside in the storage part of the RAM memory. You might want to modify the default

division based on your actual usage environment. If you for instance use only Internet Explorer, and have

not expected to install any 3rd party software, you could set the division to enable larger portion to be

used by program memory. This gives the browser a lot more memory to work with, which should increase

the execution speed when handling complex pages. Do not remove all storage memory as the operating

system can allocate temporary ﬁ les dynamically, and among other things cookies from the browser are

stored in the storage memory.
