Parts
Figures 1 through 3 on the following pages show and
describe the parts of the PTC-2124. The parts listed
below are not shown in any of the figures.
Flash EPROM
Flash EPROMs are electronic chips installed inside
the PTC. In the PTC-2124, a flash EPROM holds the
boot loader. If your PTC contains a radio, a separate
flash EPROM holds the program that controls the
radio.
Flash EPROMs can be erased and reprogrammed
while they are inside the PTC. The documentation
provided with the Symbol Pen-Based SC400 Software
Development Kit contains instructions on
reprogramming flash EPROMs. Refer to Appendix B
for ordering information.
Stylus
!
Do not write on the PTC’s screen
with an ink pen, pencil, or marker;
using these will mar the screen.
A stylus may be used to write directly on the PTC’s
screen. An optional stylus holder, which attaches to
the PTC, is available to hold the stylus when it is not
in use.
Disposable screen protectors
Disposable screen protectors, Symbol part number
30782-001, are available to protect the PTC's screen
from scratches and damage (e.g., from repeatedly
striking a soft key in an application).
