							REC SAME function
This function is used to record the same time code and user bit values on VTR1 and VTR2 when both machines are in the
record (NORMAL REC) mode. The values from the time code generator (TCG) and user bit generator (UBG) are recorded on
both VTR1 and VTR2.
Turning on the REC SAME function
!Set the VTR to the stop mode.
@Switch to the set-up menu.
#Set VTR2 item No. 507 to VTR1TC (0004). 
$Set the OPERATION MODE switch on the front keyboard to SEP.

The REC SAME function causes the time codes and user bits recorded on VTR1 and VTR2 to match only while both are in the
record (NORMAL REC) mode. Therefore, if VTR1 is not in the record (NORMAL REC) mode, the time codes recorded on the
VTR2 may lack continuity. The same user bit values continue to be recorded. Also, VTR2 always uses the TCG and UBG of
VTR1 for regeneration, regardless of the setting for item No. 507 (TC MODE). 
REC THROUGH function
When a multiple number of VTRs have been connected in a daisy-chain configuration using TC IN/OUT (LTC), this function
enables recording by using TC IN/OUT (LTC) so that the master VTRÕs time code generator value will serve as the reference
TC for all the VTRs.

In the case of the master VTR, set the TC OUT output timing to TCOUT1 irrespective of the TC MODE.
In the case of the slave VTRs, set the TC OUT output timing to TCOUT1 when E-LTC is selected as the TC MODE.

The video signals (ENCODER OUT) must be adjusted upon completion of the system connections before any signals are trans-
mitted in order to conduct accurate error-free editing.
(This adjustment may have to be repeated whenever a connecting cable is replaced or the connections changed.)
To adjust the encoder using the laptop:
!Connect the units as shown below.
If a waveform monitor and vectorscope are unavailable, observe the images on a monitor and adjust to eliminate any
color shifting.

							@Set the REMOTE/LOCAL switch to the position (LOCAL) where the adjustment is to be made.
#Conduct the adjustments using a discrete source unit.
Any deviation in the set-up level, video level, chroma level or hue will cause color shifting in the recorder. Adjust them using
a discrete player.
1) Play back a cassette tape on which standard color bars have been recorded.
2) Adjust the controls in such a way that the waveform monitor (WFM) and vectorscope (VSC) achieve the following.
Video level: Adjust this to 100IRE.
õChroma level, hue: Adjust the two controls, and place the trace of the vector waveforms at the mark          .
‚Set-up level: Adjust so that there is no deviation.
3) Conduct the same adjustments for the connected source unit.
$Adjust the SYSTEM PHASE controls.
1) Play back the standard color bars on VTR1.
2) Adjust the SYSTEM PHASE controls of VTR1.
Adjust so that the waveform monitor (WFM) achieves the following.
1. In the INT mode, expand the waveform on the WFM to 0.1ms.
2. Check the H SYNC position.
3. Now set the WFM to the EXT mode.
4. In the EXT mode, adjust the SYSTEM PHASE (H SC FINE, SC COARSE) controls in such a way that the H SYNC sig-
nal is aligned with the position in 2.

							Adjustment in display section
The brightness can be adjusted in the display section.
To adjustment the brightness:
Turn the BRIGHTNESS control or set the LCD switch to LIGHT or DARK.
The screen brightens at the LIGHT setting and is dimmed at the DARK setting.
Adjustments in set-up menu mode
The contrast, color and hue can be adjusted on the set-up menu. Use menu item No.802 (LCD CONT) for adjusting the con-
trast, item No.803 (COLOR) for the color, and item No.804 (LCD HUE) for the hue.

							The superimposed displays can be changed using the set-up menus.
What is displayed:
One of four different displays can be selected using set-up menu item No.000 (DISPLAY SEL): 1) counter value only, 2) counter
value and operation mode, 3) counter value and shooting date, and 4) counter value and shooting time.  However, the shooting
date and time are displayed only when playing back a tape which was shot using a DV or DVCAM camera recorder.
Setting whether the superimposed display is to appear on the liquid-crystal monitor:
Whether the superimposed display is to appear or not is selected in set-up menu item No.001 (LCD SUPER).
Characters displayed:
The background for the characters displayed can be changed in set-up menu No.002 (CHARA TYPE).
CTL counter display:
Either the 12-hour or 24-hour system can be set in set-up menu item No.003 (TAPE TIMER).
Besides these selections which are made using the set-up menus, the position where the superimposed characters are dis-
played can be switched to the top or bottom by pressing the COUNTER/REMAIN switch.
For details on the set-up menus, refer to pages 23 to 35.
