Self-test procedure
The self-test procedure mode of the previous generation radios (PN0-6) allows certain main functions to be tested:
●by pressing buttons 2 and 4 at the same time, the speakers can be tested. They are supplied one by one; the
display enables the connections and signals from each speaker to be checked,
●by pressing buttons 1 and 6 at the same time, the reception level can be tested (after frequency is displayed),
–9 or letter: good reception,
–
–less than 3: poor reception,
–if 2: total loss of stereo.
The self-test procedure mode of the new generation radios (NR4/5) enables certain main functions to be tested
using the combination of buttons 1, 6 and i. The messages will be displayed in the following way:
●Radio pre-code (one letter/three digits) displayed to avoid the need to remove the radio,
●speaker test with two beeps (bass - treble) from the speakers, with the tested speakers shown on the display
(front left-hand H01, front right-hand H02, rear right-hand H03, rear left-hand H04),
●displays the frequencies and levels of the tuner sensors,
●software version displayed, displays fault finding for the connected aerial if the aerial is supplied by a coaxial
cable; in this case, the display shows H15 with X = 0, 1 or 2 depending on the aerial status (0: open circuit,
1: short circuit to earth, 2: power consumption),
●audio test loudness OFF (H08), cuts any loudness for an audio test.
Note:
The source usage times in 1/6ths of an hour is also displayed (Tuner (H09)/CD (H10)/cassette (H11)/CD changer
(H12)/auxiliary (13)/MP (H14)/Total (H15)).
