PREROLL button
This is used for feeding and cueing the tape for manual editing.
When it is pressed, the tape travels to the preroll point where it stops.
The preroll time can be set on-screen.
When this button is pressed together with the IN or OUT button, the tape can be cued to
the IN or OUT point entered.
When the AUDIO ENTRY on the setup menu No.311 is set to 1, IN point has been
entered at the point where the PREROLL button is pressed even if the IN point has not
been entered.
AUTO EDIT button
Automatic editing is executed when this is pressed after an edit point has been entered.
When the AUTO EDIT button is pressed though the IN point has not been entered,
automatic editing is executed using the point at which the button was pressed as the IN
point.
PREVIEW/REVIEW buttons
PREVIEW: 
When this is pressed after an edit point has been entered, the tape travels,
editing is not performed, and the rehearsal can be activated on the screen
connected to the recorder.
If it is pressed when the IN point has not been entered, the point at which the
button was pressed is entered as the IN point, and preview is executed
accordingly.
REVIEW:If this is pressed after a block has been edited, the now edited block can be
played back and monitored on the screen connected to the recorder.
IN/SET/OUT buttons
When IN or OUT button is pressed together with the SET button, the IN or OUT point is
entered.
While an IN or OUT point is being entered, the lamp in the IN or OUT button correspond-
ing to the point being entered lights.
When this button is pressed after a point has been entered, the IN or OUT point value
appears on the counter display. When the IN or OUT button is pressed together with the
RESET button, the IN or OUT point entry is cleared.
TRIM buttons
These buttons are used to trim IN or OUT point finely.
When the “+” or “–” button is pressed while the IN or OUT button is held down, the

SHIFT:When setting the TC or UB value, first press this button to stop the data
running.
Change the digit now flashing on the display.
Each time the button is pressed, the flashing moves to the right by one digit,
and when it reaches the right-most digit, it returns to the left-most digit.
When it is kept depressed, the flashing moves consecutively.
ADJ:This is used to change the numeral of the digit now flashing on the display.
When the button is pressed once, the number is incremented by 1, and when it
is kept depressed, the number is incremented consecutively.

Also, Pressing this button when the TC or UB value are not set enables the
TCG or UBG setting values to be confirmed.

Level meters
These indicate the PCM audio signal CH1/CH2, CUE track signal and video signal levels.
The audio signal indicates the input signal levels during recording and EE selection, and
the output signal levels during playback.
The video signal indicates only the input signal levels.
Input/output level controls
These are used to adjust the recording and playback levels of the PCM audio signal
CH1/CH2 and CUE track signals and the recording level of the composite video signals.
Each control located on the upper level is for adjusting the recording level, and each
control located on the lower level is for adjusting the playback level.
These are “pull for variable” controls which means that they enable adjustment only when
they have been pulled up. The signals levels are set to the unity value (preset value)
when the controls have been pushed down.
Headphones jack
The sound being recorded, played back or edited can be monitored on stereo
headphones when they are connected to this jack.

Volume control
This is used to adjust the headphones volume and the monitor output volume.
Whether the headphones output and monitor output volumes are to be linked or kept
separate can be set on-screen menu. (Note that the headphones output volume is
normally linked.)
When the volumes are kept separate, the monitor output is set to the unity value (preset
value).
MONITOR SELECT switches
These are used to select the audio signals output to the monitor L/R channels.
Each time the “L” button is pressed, the signals output to the monitor L channel are
selected in turn in the following order: CH1, CH2, CUE and back to CH1.
Each time the “R” button is pressed, the signals output to the monitor R channel are
selected in turn in the following order: CH1, CH2, CUE and back to CH1.
The L or R lamp on the level meter display lights to indicate which signal is now being
selected. (When MONI CH SEL is set to AUTO at the on-screen menu No. 713, the
display may not match the monitor output.)
MONITOR SET button
This is used when outputting the MIX signal to the monitor L/R channels.
When the MONITOR SET and L or R buttons are pressed together, the CH1 and CH2
MIX signal can be output to the monitor L or R. When these buttons are pressed  together
again, MIX is released.
