5-6 Liquid Crystal Display (LCD) - dot matrix
The AR8000 uses a revolutionary high contrast new dot matrix LCD. Due to its
mechanical construction the LCD is best viewed from directly in front of the
receiver, a fairly wide viewing angle is maintained to the left and right hand
sides but is quickly reduced from below and particularly from above the
display.
The LCD has four lines of eleven character positions
each of which consists of 5 x 8 pixel segments. A full
test pattern may be displayed by holding the [0] key
while switching the receiver On until the sign-on
welcome message has ended. To remove the test
pattern simply switch the receiver Off/On.
The dot matrix display provides a more conventional
format of number than the conventional seven segment LED/LCD format,
compare the numbers 0, 4, 7 etc. Alphanumeric comments are also available
in menus to ease programming and identification of memory and search
banks. Graphical information may also be displayed for signal meter and band
scope.
Attractive green rear illumination of the LCD (and keypad / side panel) is
switchable for use in locations of low level lighting.
The LCD will provide frequency readout to hundreds of Hz (last digit on the
right) although the receiver is capable of tuning in smaller steps of 50 Hz.

and five vertical. The keys are multi-function and are used to input frequency
and other operational data in conjunction with the side panel [FUNC] function
key and [DIAL].
