4) Operating the keys on the set, enter the Test mode.
5) Select the item “7-02-01” and press
u
key to activate the
Switch Check mode.

6) Press each switch at part
C
to check that the mecha. deck
switch status display on the LCD screen changes as listed be-
low. (Disc type check switch)

7) Check that the Optical Pick-up block moves outward when
> key is pressed, or it moves inward when . key is
pressed. (Sled motor check)
8) At this time, check that the part B also moves in the same
direction as the direction in which the Optical Pick-up block
moves. (Tracking coil check)
9) Check that when the Optical Pick-up block moves inward as
far as it will go, the IN LIMIT SW status display on the LCD
screen is “ON” and when it moves outward, the switch be-
comes “OFF”. (IN LIMIT SW check)
10) Check that the part
D
moves in arrow direction when
y
key
is pressed, and it returns to original position when
y
key is
pressed once more. (HEAD UP/DOWN motor check)
11) At this time, check that each time the
y
key is pressed, the
INITIAL SW status display on the LCD screen changes over
between “ON” and “OFF”. (INITIAL SW check)
12) Turn the power off.
Note: Disconnect the AC adapter to turn the power off, be-
cause the POWER switch is inactive in the Test mode.

1-5. MAC Address Setting
The MAC address must be unique in the world.
On this set, hexadecimal MAC address is set for every serial num-
ber of the set.
1. How to Get MAC Address
1) Read the lower 5 digits of serial No. and add “291903 (deci-
mal)” to it, which is assumed to be D
1
.
D
1
= “Lower 5 digits of serial No.” + 291903
Example: If the lower 5 digits of serial No. is “03574”
D
1
= 3574 + 291903 = 295477
2) From Table 7-1-6, obtain D
2
and H
1
that correspond to D
1
Example: If D
1
= 295477
D
2
= 295477 – 262144 = 33333
H
1
= 04
D
1
(decimal) D
2
(decimal) H
1
(hexadecimal)
327679 or less D
1
-262144 04
327680 or more D
1
-327680 05
Table 7-1-6
3) From Table 7-1-7, obtain maximum decimal number not ex-
ceeding D
2
, which is assumed to be D
3
.
Example: If D
2
= 33333
D
3
= 33280
4) From Table 7-1-7, obtain hexadecimal number that corresponds
to D
3
, and the higher 2 digits of that number is assumed to be
H
3
.
Example: If D
3
= 33280
H
3
= 82
5) Obtain a difference between D
2
and D
3
, which assumed to be
D
4
. (0
≤
D
4
≤
255)
D
4
= D
2
– D
3
Example: If D
2
= 33333 and D
3
= 33280,
D
4
= 33333 – 33280 = 53
6) From Table 7-1-8, convert D
4
into hexadecimal number to ob-
tain H
4
.
Example: If D
4
= 53
H
4
= 35
7) The MAC address is “08:00:46:H
1
:H
3
:H
4
”. (08, 00, 46 are fixed
values)
Example: If H
1
= 04, H
3
= 82 and H
4
= 35
08:00:46:04:82:35
