Note:
Use of backlighting can significantly reduce battery life.
To turn the backlight on or off, press FUNC then L, or use the key sequence listed in your
application guide. The backlight turns off automatically when the terminal is powered off or
when the terminal has not been used for an amount of time set by the application. See the
Series 3000 Application Programmer's Guide for more information.
PDT 6800 Series Keyboard
The keyboard is used for entering data and issuing commands to the terminal. Figure 5-1 and
Figure 5-2 illustrate the standard 35-key and 46-key keyboards respectively. The keys on the
keyboard are distinguished as modifier keys and character keys. Because terminal keyboards
have fewer keys than PC keyboards, each character key can produce more than the usual one
or two characters. The modifier keys, SHF (Shift), CTL, and FUNC, used individually or in
combination, determine which character or special function the character keys produce.
Because the keyboard is programmable, your terminal may not work as described here. For
more information and illustrations of other keyboard states, see the Series 3000 Application
Programmer's Guide and your application guide.
