q Power Switch (POWER ON / OFF)

This switch turns the power of the video multiplexer on
or off. The LED lights up when the power is turned on.

Note: To prevent that the power of the video multiplexer

is turned off accidentally, install the supplied switch
protector as shown below.

SWITCH

PROTECTOR

wAlarm Reset Button (ALARM RESET)

This button resets the active Alarm mode. Pressing this
button turns off the Alarm indicator and replaces the
“Alarm” indication on the monitor screen with the camera
title.

e Alarm Indicator (ALARM)

This indicator (Red) blinks when an alarm is activated. It
changes to steady light when the auto-reset time has
elapsed or the alarm recovery signal is received from the
VTR. To turn the indicator off, press the ALARM RESET
button.

r Multiscreen Selection Button (MULTISCREEN

SELECT)

This button selects the multiscreen pattern for the moni­tor. Multiscreen is available only while the VTR is in
playback mode. Pressing this button repeatedly switches
patterns as follows:

VTR Playback Picture:

4→9→16→4 screen segments (WJ-FS116)
4→9→4 screen segments (WJ-FS109)

Notes:

• This button does not function in recording mode.

• When ON is selected for QUAD SHIFT on the MON­ITOR OUTPUT SETUP menu, the screen changes
by pressing this button as follows:
4A→4B→4C→4D→9→16 screen segments
(WJ-FS116)
4A→4B→9 screen segments (WJ-FS109)
The 4A screen is a compressed picture of channels
1 through 4, the 4B of channels 5 through 8, the 4C
of channels 9 through 12, and the 4D of channels 13
through 16. The 9-segment screen shows the pic­tures of channels 1 through 9 in a 3x3 pattern.

y Sequence Button (SEQ)

This button activates the sequence mode. In this mode,
a series of camera pictures is displayed in succession
on the monitor screen for the specified duration.

– 2 –

u Camera Selection Buttons (CAMERA SELECT)

These buttons select the camera for live picture or pic­ture recorded on the tape. When the VTR is in playback
mode and the LED on the VTR/CAM Selection button is
on, these buttons select the specified camera picture
from the tape for display on the monitor. When the LED
is off, the buttons select the live picture of the specified
camera.

i Cursor Buttons (C, D, A, B)

These buttons move the cursor in the SETUP MENU of
the Video Multiplexer, or select an area for Electronic
Zooming.

C: Downward
D: Upward
A: Left
B: Right

o Increment/Decrement Buttons (–, +)

Electronic Zooming is operated with these buttons,
Zoom In with the + button and Zoom Out with the – but-
ton. During the setup, these buttons are used to select
parameters.

!0 Set Button (SET)

This button executes the selected parameter in the
setup menu, and opens a submenu for more detailed
settings. Menu items having a submenu are identified by
a return symbol at the end of the line.

!1 Still Button (STILL)

This button selects either still or moving mode for display
of the VTR playback on the monitor. Pressing a Camera
Selection button will display the corresponding picture
either in still or moving mode. When a still picture is dis­played, the LED (Green) lights. Pressing the button
again restores the moving picture and turns off the LED.
Note: Please note that the tape continues running while

the picture is stilled. You may sometimes have to
rewind the tape to the desired position.

!2 Electric Zoom Button (EL-ZOOM)

This button specifies the zooming area in the playback
picture. Pressing this button displays the “+” sign repre­senting the centre of the area to be enlarged. While the
“+” sign is displayed for 5 seconds, move the “+” sign
with the cursor buttons to the desired position and press
the Increment (+) button. The designated area is
enlarged.
To return to the normal picture press the Decrement (–)
or the EL-ZOOM button.

!3 MENU/ESC Button (MENU/ESC)

Pressing this button for 2 seconds or more opens the
Setup Menu of the Video Multiplexer. If pressed for less
than 1 second, it functions as the Escape button and
returns you to the previous menu.
To close the Setup menu when the setup is completed,
press the button for 2 seconds.

Notes:

• Make sure to distinguish between 1-second and 2­second operation of this button.

• Opening the Setup menu does not affect the record­ing signal (REC OUT) output from the rear panel.

!4 VTR/Camera Selection Button (VTR/CAM)

This button selects either VTR playback or the camera
picture for display on the monitor. At the same time, it
disables or enables recording on the VTR, since the
connected VTR performs only playback or recording at a
time. The playback picture is displayed on the monitor if
you start playing back the VTR while the LED (Green) is
on. The camera picture is displayed on the monitor while
the LED is off. The camera picture is recorded on the
tape if you start the VTR recording.

Notes:

• If PLAYBACK AUTO is set to ON in the setup,
pressing this button is ignored, instead this button
follows the VTR status automatically. VTR is select­ed while playing back, and CAMERA is selected dur­ing non-playback mode of the VTR.

• There may be a delay of few seconds after switching
this button between VTR and CAMERA when PLAY­BACK AUTO is ON.

• Blinking of the LED is a warning that the ID code is
missing in the playback signal. This may happen
when using certain VTR types. In this case, the play­back picture goes straight to the monitor instead of
through the Video Multiplexer. As a result, the play­back picture will not be recognizable unless only a
single channel is recorded throughout the tape.

q Video Input Connectors (VIDEO IN)

These connectors accept a composite video signal from
a camera.
Note: If the input signals have a high jitter content, as in

the case of a VTR playback picture, it may not be
possible to synchronize this unit.

w Video Output Connectors (VIDEO OUT)

The video signals connected to the Video Input
Connectors (VIDEO IN) are looped through to these
connectors with an automatic 75 Ω termination.

e Alarm / Remote Control Connector (ALARM /

REMOTE)

This connector accepts the alarm signals from the asso­ciated alarm sensor units and the control signals from
the external system.

r Playback Input Connector (PLAY IN)

The playback signal from the time lapse VTR is supplied
to this connector.

t Record Output Connector (REC OUT)

The recording signal for the time lapse VTR is provided
via this connector.

y Monitor Output Connector (MONITOR OUT)

The video output signal for the monitor is provided via
this connector.

u Camera Switching Input Connector
