Function
Jitter check
Jitter rate is measured and displayed. Measurement is
repeatedly done in the cycle of one second. Read error
counter starts from zero upon mode setting. When target
block data failed to be readout, the counter advances by one
increment. When the failure is caused by minor error, it
may be corrected when retried to enable successful reading.
In this case, the counter advances by one. When the error
persists even after retry, the counter may jumpby two or
more.
Error code check
The latest error code stored in EEPROM is displayed.
Initial setting of laser drive current
Initial current value for each of DVD and CD laser is
separately saved in EEPROM.
DVD laser drive current measurement
DVD laser drive current is measured and the result is
displayed together with the initial value stored in
EEPROM. After the measurement, DVD laser emission is
kept on. Itis turned off when Standby/on key is switched
off. (It is also turned off when the primary power is
switched off.)
ADSC internal RAM data check
ADSC internal RAM data is read out and displayed.
Change the address with "CANCEL" key operation to
show the data for 11 addresses.
CD laser drive current measurement
CD laser drive current is measured and the result is
displayed together with the initial value stored in
EEPROM. After the measurement, CD laser emission is
kept on. It isturned off when Standby/on key is switched
off. (It is also turned off when the primary power is
switched off.)

Display
J*1_xxx*2_yyy*3_zz*4
*1: Jitter check display mode
*2: Jitter rate
*3: Readerror counter
*4: Focus drive value
Jitter rate is shown in decimal
notation to one place of decimal.
Focus drive value is shown in
hexadecimal notation.
Error code (play_err) is expressed
in the following convention.
Error code=0xDAXX is
expressed→DVD nn UXX
Error code=0xDBXX is
expressed→DVD nn HXX
Error code=0xDXXXis
expressed→DVD nn FXXX
Error code=0x0000 is expressed→
DVD nn F---
Error code except above→DVD nn
XXXX
*nn denotes the serial number of
history.
LD0*1_034*2_028*3
*1: Laser current measurement
mode
*2: DVD laser current
measurement
*3:CD laser current measurement
The value denotes the current in
decimal notation. The above
example shows the initial current is
34 mA and 28 mA for DVD and
CD laser.
LDD*1_034*2_032*3
*1: DVD laser current
measurement mode
*2: Initial current stored in
EEPROM
*3:Measured current
The value denotes the current in
decimal notation.
The above example shows the
initial current is 34 mA and the
measured value is 32 mA.
A*1_0FA*2_6901*3
*1: ADSC internal RAM data
check mode
*2: Address
*3: RAM data for specifiedaddress
The value is shown in hexadecimal
notation. The above example shows
the data in ADSC address 0FAh is

*1: CD laser current measurement
mode
*2: Initial current stored in
EEPROM
*3:Measured current
The value denotes the current in
decimal notation.
The above example shows the
initial current is 28 mA and the
measured value is 26 mA.
