LCD
The LCD is a shock-mounted, sunlight-readable, ¼-VGA (320 x 240 pixel)
graphic Liquid Crystal Display. A low-power Electro-luminescent (EL)
module provides backlighting to the LCD.
The LCD has two areas:
• Display area (item A)
This area displays the prompts, test and setup menus, test results, and
messages.
• Four softkey labels (item B)
These labels identify the screen-dependent function keys. To activate a
function, press its softkey (1, 2, 3, or 4), which is located on the tester’s
keypad directly below the label.
Keypad
The keypad is a sealed, waterproof membrane that has 29 keys. Table 2-1
describes the function of each key.
