Diagnostic Test
A diagnostic test program is provided to enable testing of major circuit boards in the radar
display unit. Note that the normal radar picture is lost during this test.
Proceed as follows to execute the diagnostic test:
1. Press the [RADAR MENU] key to show the FUNCTIONS 1 menu.
2. Press the [0] key three times to show the FUNCTIONS 4 menu.
3. Press the [3] key to select menu item TEST. Then, press the [ENTER] key.
Program numbers appear. The diagnostic test is executed and the screen shows test
results as shown on the next page. OKs appear for normal operation. If NG (No good)
appears, corresponding components may be defective. Consult your dealer.
4. Small squares displayed at the right bottom of the test result screen are for testing the
control and keys on the control head. As you operate these controls and keys, corre-
sponding squares are highlighted, indicating that your control/key operations are prop-
erly recognized.
5. To terminate the diagnostic test, press [STBY/TX] key once or twice.
