Display
The 4 line by 20 character display uses either a Liquid Crystal Display
(LCD) with LED backlighting or a Vacuum Fluorescent Display (VFD).
You can adjust both the contrast and backlight levels on LCD displays using
the keypad. You can only adjust brightness on VFD displays.
Keypad
The keypad is a sealed unit with 25 tactile feedback keys. The VFD version
does not include the half moon brightness key so has 24 keys. The keys are
color coded for easy identification of key functions. The keypad is designed
for hand operation. Using any other object or tool may damage the overlay
or key.
