When this is displayed, it is called "Test Mode Stop status."
In "Test Mode Stop status" and "EJECT status":
Operation will switch to the mechanism forced EJECT direction while
¡
button is pressed.
Operation will switch to the mechanism forced LOAD direction while
1
button is pressed.
In each Menu status:
The mechanism slide outer track feed will operate while the S.M. JOG key is turned clockwise.
The mechanism slide inner track feed will operate while the S.M. JOG key is turned counterclockwise.
To move according to the adjusted value set in Test Mode, Press the PRESET key in Test Mode Stop status. The adjusted value will be written
to EEPROM and the AUTO Adjustment Disabled Mode will be engaged.
Notes)
Canceling the AUTO Adjustment Disabled Mode will stop the power supply. (If a receiver is connected, disconnect the receiver power
cord.)
When a setting is changed in Test Mode and the unit is moved according to that setting, the mechanism may not operate if the set value
is faulty. When changing a set value, therefore, make a note of the original value.
In Test Mode the companion may be not only the SX-R9 but also the power jig. When the TEST2 terminal has been shorted without a bus
being received even once after RESET, the bus data will be ignored and POWER ON status determined, and the unit will operate
independently.
When the TEST2 terminal is shorted again under these conditions, the normal operation will be restored.
