Adjustment; Test Mode Stop State - Sharp MD-MS200W Service Manual

Test disc
MD adjustment needs two types of disc, namely recording disc (low reflection disc) and playback-only disc (high
reflection disc).
Type
1 High reflection disc ESYA 1014 (SONY)
2 Low reflection disc
Note: Use the low reflection disc on which music has been recorded.
Entering the TEST mode
1. Setting at port (in standby state, disc-free state or power nonconnected state)
(1) Set the port as follows.
TEST1 : "Low"
TEST0 : "High"
(2) Press the PLAY button in the standby state (it is allowed to insert the disc or to connect the power supply).
(3) Test Mode STOP [ _ T E S T _ ]
2. Setting by special button operation (in standby state)
(1) Holding down the DISP button and ENTER button, press the PLAY button.
(2) Normal mode setting initialization (BASS setting, VOL setting, etc.)
(3) Indication of microcomputer version for one second [
(4) Whole LCD lighting for 2 seconds
(5) Test Mode STOP [ _ T E S T _ ]
*When the PLAY button is pressed during indication (3) and (4), the process proceeds to (5).
Leaving the TEST mode
(1) Press the STOP button in the TEST mode stop state or version indicating state or whole LCD lighting state.
(2) EEPROM rewrite-enable area updating, adjustment error setting (so as to adjust all the items when the power supply is turned
on in the normal mode)
(3) Change to standby state

Microcomputer version
• Automatic adjustment is performed. (After adjustment the grating adjustment mode is set.)
• Continuous playback is performed (Error rate indication, jump test).
• The temperature correction is performed only when servo start is performed, but the
posture correction is not performed.
• Temperature is displayed. (Updating in real time)
• Seeing the displayed measurement value/set value, make manualadjustment to set values
within the allowable range.
• Continuous playback is performed (error rate display, jump test).
• The temperature correction is performed only when servo start is performed, but the
posture correction is not performed.
• Adjustment value is indicted.
• Adjustment value is changed manually. (in servo OFF state).
• Continuous playback from the specified address is performed.
• 1 line, 10 lines or 400 lines manual jump is performed.
• C1 error rate display (pit section), ADIP error rate display (groove section)
• The temperature correction is performed only when servo start is performed, but the
posture correction is not performed during continuous playback.
• Continuous record from the specified address is performed.
• Change of record laser output(servo gain is also changed according to laser output).
• The temperature correction is performed only when servo start is performed, but the
posture correction is not performed during continuous recording.
• Determine the position where the INNER switch is turned on.(only high reflection disc).
• The temperature correction is performed only when servo start is performed, but the
posture correction is not performed.
• The mode is changed from the TEST mode to the normal mode without adjustment.
• In the normal mode the internal operation mode, memory capacity, etc. areindicated.
• In the normal mode both temperature correction and posture correction are performed.
• Digital input information is displayed.
• Error information is displayed.
• Error information is initialized.
• Factors of digital servo are changed manually. (Each servo is turned on individually.)
• Cut-off frequency of BASS1, BASS2 and BASS3 is selected manually.
• Temperature detection terminal voltage is measured, and the reference value is set.
• Defaults are selected and set.
• Setting of EEPROM protect area is updated. (In case of protect releasing)
