2. CD tracking balance adjusting mode
“
Press the EDIT key from service mode entry status to enter this mode.
“ When this mode is activated, the function becomes CD. When the unit is powered off, it automatically powers on again.
“ In this mode, the unit automatically enters tracking balance adjustment status (tracking off) after the tray closes. In this
status, the tracking servo turns on when the CD PLAY key is pressed and play begins from that place. (If the location is
the lead-in area, “TNO = 00” and “E.TIME” are displayed and play starts.) Consequently, the initial position of the pickup
(the limit switch position) can be determined from the display when play starts.
“ In this mode, pressing the EDIT key during play activates tracking balance adjustment status. In this status, the tracking
servo turns on
when the CD PLAY key is pressed and play begins.
“
In this mode, play does not stop even if a servo error occurs.
. In this
mode, power to the CD circuitry is not cut off when the CD stops (to allow for focus offset adjustment).
“
The mode is released when the power is turned off.
