The Radio Tune Test function is for technical personnel use only.

5100 - Entering Radio Tune Test Mode:

To enter Radio Tune Test Mode, press Side Button 2 during the interval between the initial display and the completion of the self-test. Pressing Side Button 2 after the self-test has completed has no noticeable effect on the radio other than its programmed functionality. I.e., if Side Button 2 is pressed after the self-test has completed, the radio operates normally and Radio Tune Test Mode cannot be entered while the radio remains powered.

After pressing Side Button 2 during the self-test, the radio completes the self-test and displays the message "Service". The radio cycles through several informational displays, which are summarized in Table 1 below.

5300 - Entering Radio Tune Test Mode:

To enter Radio Tune Test Mode, press and hold the left button above the display during the interval between the initial display and the completion of the self-test, such as when the "SELF TEST" message is being displayed. Pressing this button after the self-test has completed has no noticeable effect on the radio other than its programmed functionality, i.e., if the button is pressed after the self-test has completed, the radio operates normally and Radio Tune Test Mode cannot be entered while the radio remains powered.
