2.5.2 Test Mode 2: Keyboard
1. Test Mode 2 is entered automatically after the
display is loaded with the Test Mode 1 pattern
of characters. Ensure that the display unit
switches are set as described in section 2.5.1.
2. Verify operation of Test Mode 2 by checking
that the characters that appear on the screen
from each keyboard key are the same as shown
on the keyboard layout diagram in Figure 2-3.
If the test fails, read MAP 0000 page 2 and go
to MAP 0100, Entry Point A.
