Installer Memory Specifications; Backup Memory Specifications - Kenwood DPX502 Service Manual

INSTALLER MEMORY SPECIFICATIONS

At specialists (or specialty stores), when the installer sends
the vehicle back to the user, they may make the store-
recommended audio confi guration.
When the user changes the setting values, when the
backup power supply was taken out at times of battery
change or when the reset button was pressed, to make it
possible to recall the setting values, the store-recommended
confi guration values can be saved into E2PROM.
The specification detail defer in "with-DSP model" and in
"without-DSP model".
[Models without DSP]
• Calling and saving the configuration is done by the
MENU.
• Items to be saved are Bass, Middle, Treble, X'over, and
Sub Woofer Level. Only one setting can be saved for
each item (Bass/Middle/Treble settings can be changed
for each source, but only one setting can be saved as the
installer memory specifi cation, and the source in which
the saving operation was carried out is saved as such).
Settings by the user other than the installer memory items
are saved into the E2PROM, and when the backup power
supply was taken out at times of battery change or when the
reset button was pressed, it is made possible to recall the
setting values saved.
• While Power ON, the memory is saved and accumulated
at a certain interval (temporary).
• Items to be saved into the memory are: Volume Offset (for
all sources) and preset frequencies (FM/AM all bands x 6
channels).

• The contents read out by the call key shall be refl ected
only to the current source at the time→EQ curve is "USER"
(Bass/Middle/Treble settings can be changed for each
source, but not reflected to Bass/Middle/Treble settings
of sources other than where the calling operation was
carried out).
• When the backup power supply was taken out at times of
battery change or when the reset button was pressed, as
the initial setting values of Bass, Middle, Treble, X'over,
and Sub Woofer Level, the saved memory is refl ected.
(Bass/Middle/Treble setting initial setting value memory is
refl ected in all sources.)
[NOTE] By such, EQ curve initial setting shall always be
"USER" (NOT "NATURAL" or "FLAT").
• When the backup power supply was taken out at times of
battery change or when the reset button was pressed, as
the initial setting values of Volume Offset (for all sources)
and preset frequencies (FM/AM all bands x 6 channels),
the saved memory is refl ected.
• In models which includes channel space switching, when
channel space is switched, TUNER-preset frequencies
are set back to the default values.
