4.4 Self-test

Test Menu
Press [RADAR MENU], [0], [0], [0], [3], and [ENTER] in this order, and the self-test result
display will appear after several seconds. Figure 4.2 shows the self-test result display. If any
error has been found in circuitry, NG appears instead of OK. The self-test is carried out at every
power-up, not when the keys are pressed. If the self-test detects an error, the message SYSTEM
FAIL appears at the lower right of the screen.
