6. Synchronization Setting (SYNC)

You can select internal sync (INT) mode, line-lock (LL) mode or the VD2 signal (multiplexed
vertical drive signal) mode.

Important Notices:

1. The priority for the sync modes is as follows:

(1) Multiplexed Vertical Drive (VD2) (Highest priority)
(2) Line-lock (LL)
(3) Internal Sync (INT) (Lowest priority)

2. The line-lock mode has a submenu for line-lock vertical phase adjustment. If the cam-

era installation is relocated, check the vertical phase adjustment again since the AC
line phase may be different.

6-1. Line-lock Sync Mode (LL)

1. Move the cursor to SYNC and select

LL.

Note:

The settings in this menu can be

made only when the multiplexed
vertical drive signal (VD2) is not
supplied to the camera.

2. After confirming that the cursor is on

LL, press

I(S). The vertical phase

adjustment menu appears on the moni-
tor screen.

3. Supply the video output signal of the camera to be adjusted and the reference camera

video output signal to a dual-trace oscilloscope.

4. Set the oscilloscope to the vertical rate and expand the vertical sync portion on the

oscilloscope.

5. Move the cursor to COARSE. The cur-

sor is highlighted.

6. Press

I(L) or I(R) to match the

vertical phase for both video output
signals as closely as possible.
(COARSE adjustment can be incre-
mented in 16 steps by 22.5 degrees by
pressing

I(L) or I(R).)

Note:

After the sixteenth step, the

adjustment returns to the first step.

7. Move the cursor to FINE.
8. Press

I(L) or I(R) to match the vertical phase for both video output signals as

closely as possible.
(FINE adjustment can be made by up to 22.5 degrees by pressing

I(L) or I(R).)

Notes:

• When the “I” cursor reaches the “+” end, it jumps back to “–”. At the same time,

COARSE is incremented by one step to enable a continuous adjustment. The
reverse takes place when the “I” cursor reaches the “–” end.

• When

I(L) or I(R) is kept pressed for a second or more, the “I” cursor moves

faster.

• To reset COARSE and FINE to the values preset at the factory, press

I(L) and

I(R) simultaneously. COARSE and FINE adjustments are preset at the factory to
zero-crossing of the AC line phase.

• If the AC line contains noise (spike noise, etc.), the stability of the vertical phase of

the camera video output signal may be disturbed.

7. White Balance Setting (WHITE BAL)

7-1. Auto-Tracing White Balance Mode (ATW)

You can select one of three modes for white balance adjustment as follows:
The factory default setting is ATW1.

• ATW1 (Auto-Tracing White Balance 1)

Move the cursor to WHITE BAL and select ATW1.
In this mode, the color temperature is monitored continuously and thereby white bal-
ance is automatically set. The color temperature range for the proper white balance is
approximately 2 600 - 6 000K. Proper
white balance may not be obtained
under the following conditions:

1. The color temperature is out of

the 2 600 - 6 000K range.

2. When the scene contains mostly

high color temperature objects,
such as a blue sky or sunset.

3. When the scene is dim.

In these cases, select the AWC
mode.

• ATW2 (Auto-Tracing White Balance 2)

Auto-tracing white balance in sodium light mode (ATW2)
When that you select ATW2 for sodium light, white balance is set automatically (no
operation needed).

Note:

ATW1 and ATW2 do not appear for WHITE BAL on the system controller setup

menu.

• Automatic White Balance Control Mode (AWC)

In this mode, accurate white balance is obtained within a color temperature range of
approximately 2 300-10 000K.

1. Move the cursor to WHITE BAL and

select AWC

PUSH SW.

2. Press

I(S) to start the white balance

setup. The PUSH SW is highlighted to
indicate that the white balance is being
set.

3. When the white balance setting is completed, the PUSH SW returns to normal display.

Note:

If white balance is not set, the PUSH SW is being highlighted.

4. When you want to adjust the white bal-

ance manually, press

I(R) to select

AWC and press

I(S). The AWC

menu appears on the monitor screen.
(When ATW is selected, pressing
I(S) displays the ATW menu.)

1 (1 - - 16): 0 degrees
2 (1 - - 16): 22.5 degrees
