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 close the disc lid or to connect the power supply).

(3)Test Mode STOP [ T E S T _ ]

2.Setting by special button operation (in standby state)

Test mode: Perform it with the remote control.

(1)Press and hold the "PLAY MODE" button on the remote control and press the "PLAY" button.

(2)Release only the "PLAY MODE" button.

(3)Press and hold only the "PLAY" button and press the "VOL- UME–" button.

(4)Normal mode setting initialization (BASS setting, VOLUME setting, etc.)

(5)Test Mode STOP [ T E S T _ ]

(6)Press "VOLUME+" to check the microcomputer version.

(7)Press "VOLUME–" to light up all the LCDs.

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.

(3)Change to standby state

Shipping setting method

(1)Insert the rechargeable battery. Do not close the compartment.

Test Mode

1. AUTO 1 Mode

• Perform preliminary automatic adjustment.

 

• If the combination of mechanism and pickup

 

PWB has been changed, be sure to start from

 

AUTO1.

 

 

2. AUTO 2 Mode

• Perform ATT (attenuator) automatic adjustment.

 

• Perform continuous playback (error rate display,

 

jump test)

3. TEST-PLAY Mode

• Continuous playback from the specified address

 

is performed.

 

• 1 line, 10 lines or 100 steps 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.

4. TEST-REC Mode

• 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.

5. MANUAL 1 Mode

• Temperature is displayed.

 

• Seeing the displayed adjustment value, perform

 

preliminary manual adjustment.

 

(Error rate indication, jump test)

 

 

6. MANUAL 2 Mode

• Temperature is displayed.

 

• Seeing the displayed adjustment value, perform

 

ATT (attenuator) manual adjustment.

 

• Continuous playback is performed

 

(error rate display, jump test).

7. ERROR INFORMATION

• Error information is displayed.

Mode

• Error information is initialized

8. NORMAL Mode

• 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.

9. EEPROM Mode

• Factors of digital servo are changed manually.

 

• 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.
