NVRAM Tests [04]
Front Panel Tests [05]
User confirmation is necessary during the front panel tests.
The following keys are used for user feedback:
115 Pink Noise On Generates internally on the
Sti5505 a pink noise audio signal that will be
passed to all the DACs were it is converted to an
analogue audio signal.
116 Pink Noise Off Switches off the pink noise audio
signal generated with DS_HostdPinkNoiseOn.
117 Sine On Generates a sine signal of 1 kHz on the
analogue output. The sine signal digital data are
stored in the audio buffer in SDRAM, passed
through the audio decoder and without any fur-
ther processing to the audio DAC were it is con-
verted to an analogue audio signal. To stop the
sine, press the STOP key on the local keyboard.
118 Sine Burst 1kHz Generates a sine signal of 1 kHz
on the analogue output that lasts about four sec-
onds. The generation of the signal is the same as
in DS_HostdSineOn.
119 Sine Burst 12kHz Generates a sine signal of
12kHz on the analogue output that lasts about
four seconds. The generation of the signal is the
same as in DS_HostdSineOn.
120 Colour-bar On Enables colour bar in the DENC in
the Sti5505. To make the colourbar visible on the
TV screen via the SCART output, the following
commands must also be given: 1406: Colour
Setup Normal 1408: Scart Switch DVD
121 Colour-bar Off Disables colour bar in the DENC
in the Sti5505.
122 NvramWrR Checks the NVRAM by writing and
reading patterns to and from all locations. This
test is non-destructive. However, this test should
be used with great caution. Potential danger ex-
ists when power loss occurs when the test is be-
ing executed. The contents of the NVRAM are
changed during the test and are restored after
the test. However, power loss may occur before
the original contents are restored. Therefore, this
test is not used in script and menu mode.
123 NvramI2c Checks the interconnection between
the I2C controller on the STi5505 and the
NVRAM.

128 129 Pink Noise On Channel X Generates internally
on the Sti5505 a pink noise audio signal that will
be passed to the DACs on the DAC board where
it is converted to an analogue audio signal. Only
one channel at the time will generate a pink noise
audio signal. X indicates a channel number. It
can be turned off with the nucleus 116. 124 =
ch1, . . . . ,29 = ch6

400 Resets the NVRAM. After the reset of the
NVRAM, nucleus 404 will give error 40402:
"NVRAM error log is invalid". Introducing an error
can rectify this. (E.g. playing a disc upside down).
To reset the error log, it is recommended to use
nucleus 407.
404 Line1 Error Log Reads the error log from NVRAM.
The information is displayed on the local display
and is send to the serial port. With the PREV and
NEXT key it is possible to step through the log-
ging information on the local display. The STOP
key is used to exit this nucleus at any time.

Number Nuclei
405 Line1 Lifetime Log Ends the lifetime log. The in-
formation is displayed on the local display and is
send to the serial port. The following statistics will
be read from the NVRAM: Power On Time. The
time in hours that the SACD player was turned on.
Playing Time CDDA and VCD. The time in hours
that the disc has been spinning summed up for
both playing CDDA and VCD discs. Playing Time
DVD. Like above but for DVD discs. Times Tray
Open. The total number of times the tray has
been opened. With the PREV and NEXT key it is
possible to step through the logging information
on the local display. The STOP key is used to exit
this nucleus at any time.
406 Line1 Application Version Reads the version of
the application software from a fixed location in
the NVRAM.
407 Line2 Error Log Reset Resets the error log.
408 Line2 Lifetime Log Reset Resets the lifetime log.
409 Line2 Region-Code Reset Resets the region code
change counter of the SACD player.

500 Echo Checks the interface between the SACD
Monoboard and the slave processor on the front
panel by sending an 'echo' command. The I2C
connection will be tested.
501 Version Returns the ROM software version and
internal ID of the slave processor of the front pan-
el.
502 Segment Checks the local display by lighting four
test patterns. The following test patterns are:
Show a starburst Light all horizontal segments
Light all vertical segments Light all segments
User confirmation is necessary after each test
pattern.
503 Label Checks the local display and LED of the
front panel by lighting all labels and LED in five
steps: Light the first label grid. Light the second
label grid. Light the third label grid. Light all label
grids. Light the LED. User confirmation is neces-
sary after each test pattern.
504 Led Switches the LED on. User confirmation is
necessary.
505 Keyboard Checks the local keyboard. The local
display gives feedback on the keys that are
pressed by showing their code: [LKB_xxxx N_yy].
[xxxx] Means the key-code and is hexadecimal.
[yy] means the number of times this key was
pressed. All keys must be tested. User confirma-
tion is necessary at the end of the test. However,
the PLAY, PREV and NEXT keys are also part of
the keyboard test itself. Therefore it is needed to
press these keys for one second.
506 Remote-Control Checks the interface between
the remote control and the front panel. The local
display gives feedback on the remote key that is
pressed by showing its code: [RC C_xx N_yy].
[xx] Means the RC-key-code and is hexadecimal.
[yy] means the number of times a RC-key was
pressed. At least one key must be tested. User
confirmation is necessary. The PLAY key con-
firms that at least one RC-key is tested.
