PRECAUTIONS use)
When operation is incorrect or a malfunction is
observed:
While operation, if any abnormal condition (strange sound,
smell or smoke) or a malfunction (no picture, etc.) is observed,
stop using the camera immediately, turn the power off, then
call your local deater.
Cleaning
Turn the power off and wipe off the dirt with a dry soft cloth. If it
is extremely dirty, use furniture cleaner to wipe it off.
To clean the lens, use a blower of lens cleaning tissue (avail-
able from any camera dealer).
e
Do not point the camera at the sun. This could damage
the camera whether it is operating or not.
Do not shoot any source of bright light. {f the object con-
tains very bright areas, bright vertical or horizontal lines may
appear on the screen. This is called “smear”, a phenomenon
which often occurs with solid-state pickups, and is not a mal-
function.
Do not disassemble the camera and never touch parts in-
side the camera as you could damage the camera.
Do not allow anything to get inside the camera. If a metal
or flammable object gets inside the camera, it may cause a
malfunction.
Handle with care. Do not drop the camera or subject it to
shocks and vibrations to avoid possible damage.

#« : For shooting under the artificial light such as halo-
gen lamps (colour temperature approx. 3200 K).
Notes:
@ When using the camera under a fluorescence light with
high shutter speed, the white balance may change peri-
odically.
The automatic tracing system may not function proper-
ly when shooting with non-standard lighting or lighting
with a colour temperature that exceeds the range of the
camera. Because it uses a TTL system, if a coloured
object is shot (especially one with a single colour) that
fills most of the camera’s field of view, the colour tem-
perature may be judged incorrectly and the correct
white baiance adjustment may not be possible. In such
a case, set to the “MANU” position.

@ Be careful not to turn the IRIS LEVEL contro! beyond its
limits as this could cause a malfunction in the camera's
auto-iris control.
@ SHUTTER mode select switch
This varies the shutter speed (the time the change is
stored). Normally, when a fast-moving object is being shot,
still or slow-motion played back pictures will be blurred. In
this case, switching the shutter speed from the normal
speed of 1/50 second to a faster speed allows each frame
to be recorded with greater detail, at the higher speed.
When using a manual iris lens, the brightness of the pic-
ture image will be fixed by setting this switch in AUTO
(Automatic electronic shutter) position, as the shutter
speed is automatically varied according to the light inci-
dent.

Caution:
¢ The automatic electronic shutter function is not acti-
vated for a light object to be shot, such as in outdoor
condition. In such a case, use the camera with the
auto-iris or manual-iris.
Notes:
e Faster shutter speeds require more light than the nor-
mal speed. (In the 1000 mode, the sensitivity is approx.
1/20 that at normal speed; in the 10000 mode, approx.
1/200.)
@ When shooting with the faster shutter speed, or when a
light object is being shot by setting in AUTO position
(the shutter speed becomes faster), the brightness and
white balance may change periodically. Shooting with
artificial lighting (especially fluorescent lights) will cause
the pictures to flicker. Smear (bright horizontal or verti-
cal lines) which can often be seen with solid-state pick-
ups may appear in the picture.

e@ Faster shutter speeds require more light than the nor-
mal speed. (in the 1000 mode, the sensitivity is approx.
1/20 that at norma! speed; in the 10000 mode, approx.
1/200.)
e When shooting with the faster shutter speed, or when a
light object is being shot by setting in AUTO position
(the shutter speed becomes faster), the brightness and
white balance may change periodically. Shooting with
artificial lighting (especially fluorescent lights) will cause
the pictures to flicker. Smear (bright horizontal or verti-
cal lines) which can often be seen with solid-state pick-
ups may appear in the picture.

@ Sync mode switch
The internai/external sync mode (automatic) or line-lock
syne mode (or H/V lock mode) is available with the TK-
1281EG. Set the sync mode switch correctly.
LL position:
In the line-lock setting, the camera’s vertical synchroniza-
tion can be driven by the 50 Hz AC signal in the power
lines. To select power lines phase-locked sync, set the
switch to the LL position.
Furthermore, when an external H/V sync signal is input, the
camera automatically switches to the H/V lock mode.
Notes:
e Do not supply an external sync reference signal when
using the camera in line-lock mode.
e In the line-lock sync mode, synchronization may not be
correct for a few seconds after the power is turned on;
this is not a malfunction.
VE (internal/external) position:
Select internal/external sync by setting the sync mode
switch to the I/E position. with this setting, when the exter-
nal sync reference signal is input, the camera switches to
the external sync mode, and when no signal is input, rhe
camera switches to the internal sync mode automatically.

@ BLC (Back Light Compensation) switch
This function makes the iris focus on an object to be shot
and is located near the center position of the screen.
Brightness area
Set this switch to “ON” at the time of back-light.
ON (upper side): Back-light compensation is activated.
The iris will be opened when the circum-
ference is lighter than the center of the
screen.
The iris will be closed when the circumfer-
ence is darker than the center of the
screen.
OFF (lower side): Back-light compensation is not activated.
Notes:
e This function is activated when the camera SHUTTER
mode select switch is set to AUTO position and when
using the galvanometric auto-iris lens or the video-
level-sensing auto-iris lens.
® This function is not effective when the difference of the
brightness of the center of the screen and its circumfer-
ence is smail.
@ AGC (Automatic Gain Control) switch
This automatically increases the camera’s sensitivity when
the level of ambient light drops.
ON (upper side): AGC is activated.
OFF (lower side): AGC is not activated.

© V phase adjustment
If the camera is to be used in the line-iock sync mode, the
vertical phase may require adjustment to synchronize the
vertical phase of the camera with other camera in the sys-
tem. (Vertical phase is adjustable over the range of +90°.)
Make this adjustment when the vertical phase of the
camera does not match with other cameras (or systems).
For correct adjustment, use a multichannel! oscilloscope.
This vertical phase adjustment can only be made when the
camera is operating in the line-lock sync mode
Notes:
@ When AC power line frequency is of 60 Hz, the line-lock
sync operation is not possible.
@ This adjustment is necessary only when the fine-lock
sync operation is. performed.
Ou phase adjustment
For adjusting the horizontal phase when gen-lock (or H/V
lock) operation is performed. Adjust with reference to other
camera(s) in the system.
Notes:
@ Gen-lock (or H/V lock) operation may become unstable
using a signal containing severe jitter (vertical or hori-
zontal picture vibrations) such as a video recorder play-
back signal.
e@ This adjustment is not necessary unless gen-lock (or
H/V lock) operations are performed.
@ Sync mode switch
The internal/external sync mode (automatic) or line-lock
sync mode (or H/V lock mode) is availabie with the TK-
1180E. Set the sync mode switch correctly.
LL position:
in the line-lock setting, the camera’s vertical synchroniza-
tion can be driven by the 50 Hz AC signal in the power
lines. To select power lines phase-locked sync, set the
switch to the LL position.
Furthermore, when an external H/V sync signal is input, the
camera automaticaily switches to the H/V lock mode.
Notes:
e Do not supply an external sync reference signal when
using the camera in line-lock mode.
@ In the fine-lock sync mode, synchronization may not be
correct for a few seconds after the power is turned on;
this is not a malfunction.
Line-lock sync operation is possible only when used
with an AC power source (AC 24V, 50 Hz)
1/E (internal/external) position:
Select internal/external sync by setting the sync mode
switch to the VE position. with this setting, when the exter-
nal sync reference signal is input, the camera switches to
the external sync mode, and when no signal is input, the
camera switches to the internal sync mode automatically.
@ SC phase fine adjustment control
@ SC phase coarse adjustment switch
For adjusting the colour sub-carrier phase when gen-lock
operation is performed. Adjust by changing the setting of
the SC phase coarse adjustment switch (A/B) in conjunc-
tion with the SC phase fine adjustment control with refer-
ence to other camera(s) in the system.
Notes:
e Gen-lock operation may become unstable using a sig-
nal containing severe jitter (vertical or horizontal picture
vibrations) such as a video recorder playback signal.
@ This adjustment is not necessary unless gen-lock oper-
ations are performed.

© V phase adjustment
if the camera is to be used in the line-lock sync mode, the
vertical phase may require adjustment to synchronize the
vertical phase of the camera with other camera in the sys-
tem. (Vertical phase is adjustabie over the range of +90°.}
Make this adjustment when the vertical phase of the
camera does not match with other cameras (or systems).
For correct adjustment, use a multichannel oscilloscope.
This vertical phase adjustment can only be made when the
camera is operating in the line-lock sync mode
Notes:
@ When AC power line frequency is of 60 Hz, the line-lock
sync operation is not possible.
When adjusting the V phase control to observe the AC
24 V waveform, connect the positive pin of a probe to
either of the power input connector.
This adjustment is necessary only when the line-lock
sync operation is performed.
