DIAGNOSTICS MENU
The Diagnostics menu offers more levels of diagnostics. The Diagnostics menu is only accessible when the power-up
tests show that a hardware component has failed. To enter the Diagnostics menu, press START.
To access the Diagnostics menu when no errors have been detected by the power-up tests, induce a power-up failure
from the keyboard by holding down any key (except STOP) from the time the 318 338 is turned on to the time the power-
up self tests are completed (approximately 7 seconds).
When first entered, the screen should look like Figure 3-3. To begin testing, press a data entry key equal to a menu
number. Press X to return to Diagnostics menu. Press any MENU key to leave the Diagnostics menu and begin
operation.

LOOP and DISP (display) are the user-changeable fields in each test (except for the KBD, CRT, CLK, T/H, and N & DLY
tests). Some tests have more fields. such as the ALL or SINGLE SELECTION field and the DATA ENTRY field. Refer to
Figures 3-4 and 3-5 while reading the following paragraphs.
