PREPARATIONS FOR OPERATION
Recording Time Codes in Continuation of Time Codes Recorded on Tape
The GY-HD100 also incorporates a time code reader. There-
fore, when the unit enters record mode from record-standby
mode, it can read the time code data recorded on the tape
and record time codes in continuation of the existing data.
The recorded user’s bit data are identical to the user’s bit data
recorded on tape.
* However, approximately ±1-frame variations may occur in
scene accuracy.
To enable this function, set the time code related switches as
follows before starting recording.„Setting
Set the TC GENE. switch inside the LCD door to REGEN.
MEMO
The time code framing mode automatically becomes the
mode (drop frame or non drop frame) already recorded on
the tape.
Presetting and Recording of Time Code
The time codes from the internal time code generator can be
recorded at the time of recording scenes.
• The TC/UB/CLOCK menu screen differs depending on
whether the FRAME RATE item on the VIDEO FORMAT
menu screen is “60/30” or “50/25”. 
To preset the Time Code, make the following settings.
„TC GENE. switch
Set to REC or FREE.
„TC/UB/CLOCK menu screen (FRAME RATE: 60/30)
Use the DROP/NON DROP item to select the framing
mode for the time code generator.
MEMO
Drop frame/Non-drop frame mode
In the NTSC system, the actual number of frames per 1 sec-
ond is approximately 29.97 frames, but per time code 30
frames are processed. To compensate for this difference,
the mode called “drop mode” drops frame 00 and 01 for
every minute not divisible by 10.
The “non-drop frame mode” is when no frames are dropped
and the actual time shift neglected.
„TC/UB/CLOCK menu screen (FRAME RATE: 50/25)
Whether or not user’s bit data should be recorded can be
selected with the UB REC item on the TC/UB/CLOCK
menu screen.

PREPARATIONS FOR OPERATION
White Balance Adjustment
CAUTION
• Do not adjust using any highly reflective objects, such as
metal, etc., as this may result in improper white balance
adjustment.
• The FAW (Full Auto White balance) function cannot pro-
vide optimum white balance with a subject outside the
FAW adjustment range, for example when it contains only
a single color or not enough white color.
• The accuracy of the FAW (Full Auto White balance) is
inferior to that of the Auto white balance.
• When the power is turned on with the FAW mode
selected, it takes about 10 seconds for the FAW adjust-
ment to be completed.
Do not shoot within this interval.Since the color of light (color temperature) varies depending
on the light source, it is necessary to re-adjust the white bal-
ance when the main light source illuminating the subject
changes.
„White Balance Adjustment
Two kinds of white balance adjustment results can be stored
in memories AUTO A and AUTO B.
„Adjustment procedure
1.
Set the following switches.
• Set the POWER switch to ON.
• Set the IRIS mode switch of the lens to A (Auto).
• Set the FULL AUTO switch to OFF.
2.Set the ND filter switch according to the current lighting.
3.Set the WHT.BAL switch to A or B.
4.Place a white object near the center of the screen under
the same lighting conditions as the target subject and
zoom in to fill the screen with white.
5.Press the AWB (Auto White Balance) button.
“AUTO WHITE A, B OPERATION” is displayed in the
viewfinder while the auto white balance adjustment circuit
operates.
When correct white balance is obtained, the approximate
color temperature is displayed together with “AUTO
WHITE A, B OK” for about 5 seconds.
„Error messages
If the adjustment ends abnormally, an error message, as
described below, blinks for about 5 seconds.
• NG: OBJECT (Improper object)
Displayed when there is not enough white color on an
object or the color temperature is not suitable.
Replace the color temperature conversion filter or use
another white object and re-adjust the white balance.
• ERROR: LOW LIGHT (Insufficient illumination)
Displayed when the illumination is dim. Increase the illumi-
nation and then re-adjust the white balance.
• ERROR: OVER LIGHT (Excessive illumination)
Displayed when the light is excessively bright. Decrease
the illumination and then re-adjust the white balance.
„Full Auto White Balance (FAW)
The FAW function adjusts the white balance value automati-
cally as the lighting condition changes.
This mode is convenient when you have no time to adjust the
white balance or when the camera is moved frequently in and
out of places under different lighting conditions.
„Setting procedure
The FAW function can be activated with the FAW item on
the SWITCH MODE menu screen. The FAW function can
be allocated to one of the white balance switching switches
A, B, or PRESET.
