NOTES REGARDING SERVICES OF THIS UNIT AND FEATURES OF SYSTEM
1. Be sure to refer to the instruction manual of UD-7 of this
system for the operation.
2. This unit is the receiver that is mounted with tuner and am-
plifier. However,
as INPUT SELECTOR
IC is incorporated into .
the graphic equalizer (GE-711)}, signal system goes through
the graphic equalizer. Therefore, radio waves 'cannot be
received with this unit alone.
'
When you listen to radio waves with this unit alone, con- -
nection must be made by the following method:.
a) Facilitated connection method, or b) Regular connection
method.
;
{instead
of tuner output,
AG output can also be connected
to X09 side)
:
'
a) Facilitated connection method {It can be connected at
once after case is opened)
*
:
Cennect the output pin TP7{Lch} and TP9(Rch) of the tuner
board (X05, A/6) with the test pin TP1{Lch) and TP3(Rch)
of main board. (X09) (B/5). <Fig. 1> (Output decreases

board (X05. A/6) which stands against the rear wall with
lead wire (for input} of R41(Lch) and R2{Rch) of main board
{X09) (A/S) which is installed below the tuner board. With
__ this operation, action of the surround circuit which cannot
be checked with procedures of a) for output can be checked.

A/6) for activating the microprocessor normally with GND
of chassis this time)
3. The small radiator cover is attached to this unit. Use it to
check power transistors and so on by removing it. In addi-
tion, the main board can be checked by removing the bot-
tom board after detaching the case from the unit. (For further
detail, refer to the disassembly method for repair)
4. As anew function, one pattern of graphic equalizer has be-
come able to be selected and stored into memory at each
INPUT SELECTOR. The memory can be conducted by GE
- microprocessor. The REC level set by CRLS at each INPUT
SELECTOR
{excluding
TAPE)
can
also be stored
into
memory.
The
memory
can:
be conducted
by DECK
microprocessor.

6. LED for VOLUME
(Part number: B30-1284-08}
It is basically the LED for volume, which serves as one part
of master VOL ass'y (R29-5042-05). However, the LED can
be easily removed with tweezers after removing the volume
thumbscrew when LED malfunctions.
e
Ai TIMER,
timer for wake-up, increases its volume ev-
ery 30 seconds at three stages. Although
its main
microprocessor is the GE microprocessor, it functions in
connection with the tuner and amplifier of unit. (This time,
A|. LOUDNESS of GE is not subject to operation)
© Al TIMER2, timer for wake-up, playbacks the first and
second track of CD, then receives the radio broadcast-
ing automatically.

5. The A1, sensor for remote-control light receptor, of XO5 uses
initially WO2-1049-05 and uses W02-1048-05 thereafter.
They can be installed on printed board even though their
shapes and the location of terminals are different from each
other.
7. Exchange the fuse resistance mounted on the printed board
of power-source transformer for a new one after removing
the transformer and putting it on the side of the set. °-
