ADJUSTMENT
●
For Pre-Mastered Disk
13. The set will enter high-reflection pit beta
play mode and adjustments in items
5,6,7, and 8 should be conducted.
14. After adjustments, the set stops. Eject
the disk and the adjustment is complete.
∗
During the test mode, rough adjust-
ments of the EF balance is conducted
at the same time. However, the adjust-
ments are conducted automatically and
there is no need for outside operation.

Adjustment Parameter
Adjustment condition : Restart after setting
LADJ1 terminal to high
Adjustment Key : Track UP/DOWN key
Confirmation Key: Manual UP/DOWN key
(Depending on a set, press on adjustment
key)
Notes
1. After adjusting for a media, it must be
always confirmed. When another media is
adjusted without confirming it, E2PROM
data will be damaged.
2. When focus bias values are set to extreme
UP or DOWN, focus will come down. It
could be recovered by re-try, but there is a
possibility for errors and key may become
ineffective. When this happens, reset and
start again.
(The same will happen when data is con-
firmed with an extreme value.)
3. E-99
E-99 is a mechanical error but E-99 is also
display when E2PROM data is damaged.
There is a possibility for destroying
E2PROM data when power supply is on
(BU UP) when installing or removing
wires. Therefore, this must be done while
power supply is off (BU UP off).
The same applies for pulling or inserting
card cords (flexible cords) that come in
contract with the mechanism. (Normal
operation cannot be expected by setting
TO terminal to high, as with MDS-100.)
4. About E2PROM
E2PROM contains various initial data for
MD and DSP. Adjustment data re-writes
part of the data while making adjustments.
Therefore, it must be noted that, for those
with no initial data, an error could occur.
Also, as MD mechanism is made to
accommodate LP, the E2PROM capacity
is changed from 1k to 2k. Since internal
tables are different, it must be noted that
those used with MDS-2000, MDS-2100,
and MDS-2200 systems are not usable.
