End Cap/Battery Pack Assembly; Flash Eprom - Symbol PTC-960X User Manual

The screen is a liquid crystal display (LCD).
Depending on the option ordered, the screen can
show four lines with sixteen characters each or
sixteen lines with sixteen or twenty-one charac-
ters each. Your display may also be able to dis-
play graphics.
The display's contrast can be changed through
the PTC-960X's keyboard, if your PTC's applica-
tion program has been set up to allow this option.

End cap/battery pack assembly

The PTC handle's end cap and the nickel-cad-
mium battery pack are combined in a single
module. Removing the end cap also removes the
battery pack. When the battery pack is replaced,
the entire module is replaced with a new one.

Flash EPROM

A flash EPROM is an electronic component that
is installed inside the PTC. It contains the PTC's
data collection program and determines the
PTC's key functions, the display prompts and
messages, and how and when the PTC prints or
transmits data.
The flash EPROM can be erased and repro-
grammed while it is inside the PTC. First, the
PTC must be connected to a host computer via
a cable connected to its accessory connector or
by being placed in the optional SC-960X or
MC-960X communication cradle.
Then, using software in the PTC's operating
system, you can erase the flash EPROM and
reprogram it with a new program from the host
computer.
