Display
The PTC-860’s display screen shows the information you type
or scan into the PTC and messages and instructions from the
PTC or the host computer. The screen is a supertwist liquid
crystal display (LCD).
The display can show up to sixteen lines of information, each
line sixteen or twenty-one characters long. In addition, the
display is graphics supported, which allows a variety of
character sets to be displayed and enables the 16-line display
to emulate an 8-line display.
Above the display are two light-emitting diode (LED)
indicators. The green LED glows when the battery pack is
being charged. The red LED glows when the batteries are low.
The low-battery LED works only when the PTC is turned on.

Elastic strap
A wide elastic strap on the back of the PTC is used as a hand
strap. It secures the PTC to the palm of your hand, making it
easier to hold onto the PTC when you are using it.

Keyboard
The keyboard on the PTC-860 can have fifty, forty, or
twenty-four keys. Each keyboard has two different types
of keys: data keys and function keys.
