● Starting DIAG
Press the “STANDBY/ON” key of the main unit while simultaneously pressing the “INPUT MODE” key and the “MULTI
CH INPUT” key to activate the DIAG function.
● Starting DIAG in the protection cancel
mode
If the protection function works and causing hindrance
to trouble diagnosis, cancel the protection function as
described below and it will be possible to enter the
DIAG mode. (The protection functions other than the
excess current detect function will be disabled.)

ing those two keys indicated in the figure abov e . At this time,
keep pressing those two keys for 3 seconds or longer.
In this mode, the “SLEEP” segment of the FL display of the
main unit flashes to indicate that the mode is DIAG mode
with the protection functions disabled.
CAUTION!
Using this product with the protection function disabled
may cause damage to itself. Use special care for this point
when using this mode.
When the monitor is connected, DIAGNOSTIC MENU
appears on its screen as shown in the figure.
On the FL display of the main unit, an opening message
(including the version and the protection history) appears

When there is a history of protection function:
The FL display appears as shown below depending on the
type of the protection function.
The protection function worked due to excessive current through the amplifier. Causes
could be a short at the speaker terminal or a
defect in the amplifier. The protection function activates immediately to turn off the
power, with no history display at turn-on, if
the amplifier is defective.

The protection function worked due to a defect or overload in the power supply. If the
power is turned on with the abnormality unsolved, the protection function works in about
1 second to turn off the power.
The protection function worked due to a DC
voltage appearing at the speaker terminal.
A cause could be a defect in the amplifier. If
the power is turned on with the abnormality
unsolved, the protection function works in
about 3 seconds to turn off the power.
The protection function worked due to the
temperature limit being exceeded. Causes
could be poor ventillation or a defect related
to the thermal sensor. If the power is turned
on with the abnormality unsolved, the protection function works in about 1 second to
turn off the power.
For detection of each protection function (except I-PR OTECT)
RX-V757/DSP-AX757/DSP-AX757SE
, refer to DIAG MENU No.10 AD DATA (p.42).
● History of protection function
When the protection function has worked, its history is stored
in memory with a backup. Ev en if no abnormality is noted while
servicing the unit, an abnormality which has occurred previously can be defined as long as the backup data has been
stored.
The history of the protection function is cleared when DIAG is
cancelled by selecting PRESET RESERVED (Memory initialized) of DIAG menu No.9 or when the backup data is erased.
● Display during menu operation
During the DIAG operation, the menu list described in
the section of the startup screen appears on the monitor
screen and the function at work is indicated on the FL
indicator. The contents displayed during the function operation are described later in the “Details of DIAG menu”
section.
The signal input through the multi ch input is output.
The speaker impedance can be selected.

Segment conditions of the FL driver and the FL tube are
checked by turning ON and OFF all segments. Next, the
operation of the FL driver is checked by using the dimmer
control. Then a short between segments next to each other
is checked by turning ON and OFF all segments alternately
(in lattice). (In the above example, the segments in the second row from the top are shorted.)
The test noise based THX is output to the channel specified
by the sub-menu from the DSP.

PRESET RESERVED (Initialization reserved) / PRESETRESERVED(初期化予約)
Initialization of the back-up RAM is reserved. (Actually, initialization is executed the
next time that the power is turned on.) Select this sub-menu to reset to the original
factory settings or to reset the RAM. Use PRESET RESERVED to erase the protection history.
CAUTION: Before setting to the PRESET RESER VED, write down
the existing preset memory
content of the Tuner in a table as shown below. (This is because setting to the PRESET RESERVED will cause ALL user
memory contents to be erased.)
