It is recommended to have a maintenance
inspection carried out periodically by a qualified
service employee. The interval depends on the
usage conditions.
- When the set is used in a living room the
recommended interval is 3 to 5 years.
- When the set is used in the kitchen or garage this
interval is 1 year.
During the maintenance inspection the above mentioned
"safety instructions for repair” should be carried out.
The power supply and deflection circuitry on the
chassis, the CRT panel and the neck of the CRT should
be cleaned.
Warnings
1.When a camera or accessory is connected or
disconnected, the monitor should always be switched
off by the power switch (at the rear side of the
monitor). Only operating the stand-by knob is not
sufficient !
2.In order to prevent damage to ICs and transistors, all
high-voltage flash-overs must be avoided.
In order to prevent damage to the picture tube, the
method shown in Fig. 3.1 should be used to discharge
the picture tube. Use a high-voltage probe and a
multimeter (position DC-V). Discharge until the meter
reading is 0 V (after approx. 30s).
CL 26532098/042

3.ESD Ald
All ICs and many other semiconductors are sensitive to
electrostatic discharges (ESD).
Careless handling during repair can drastically shorten
the life. Make sure that during repair you are connected
by a pulse band with resistance to the same potential
as the earth of the unit.
Keep components and tools also at this same potential.
4. Be careful when taking measurements in the high-
voltage section and on the picture tube panel.
5.When making settings, use plastic rather than metal
tools.
This will prevent any short-circuit and the possibility of
false made adjustments
VIM6
6.Never replace modules or other components while
the unit is switched on (pull-out the mains cord to
switch-off the monitor).
7.After repair the wiring should be fastened once
more in the cable clamps for this purpose.
8.It is necessary to connect first the cameras to
the camera inputs, before switching on the
monitor. In this way you can prevent short circuit of
camera input during camera connection and
therefore prevent damaging of input transistor.
9.When no input signals are connected to the
monitor, the screen will be blanked.
Notes
1.The direct voltages and oscillograms are average
voltages. They have been measured by using a
camera with a random picture and under the
following conditions:
- Adjust brightness and contrast control for the
mechanical mid-position;
- Volume control in middle position.
2. The semiconductors indicated in the circuit
diagram(s) and in the parts lists are completely
interchangeable per position with the
semiconductors in the unit, irrespective of the type
indication on these semiconductors.
3.Diagram notes;
The circuit diagrams are prepared for different
types of system monitors. On each diagram
symbols may be add to components to identify for
which type of monitor that component is available
in the diagram.

9. Circuit Description
Differences
with
the
VM8
system
:
In
respect
to
the
field
calls
of
the
VM8
system
(See
Training
Manual
VMB8
service
code
4822
727
20401), the
VM6
system
is
improved
on
several
points like:
e The use of other components in the camera interface and the deflection part
An other transformer in the power supply
Several software improvements
For the POS monitor an extra Slave twisted pair interface
The Slave monitor has a Twisted pair input
The EHT is increased to improve picture quality
A system on/off switch at the back of the monitor.
The
deflection
part
differs
(electronically)
of
that
of
the
VM8
system.
A
new
deflection
control
IC
is
introduced
(TEA
2037A)
which
generates
not
only
the
horizontal
and
vertical
drive
but
also
the
Vertical
feedback
pulses
(VFB).
The
DC
level
of
the
input
stage
(pin
15,
7405)
is
determined
by
3402.
The
value
of
3402
is
chosen
in
such
a
way
that
only
the
synchronisation
pulses
of
the
video
signal
is
fed
into
the
input
stage
of
7405.
After
the
input
stage
these
pulses
are
fed
in
the
phase
detector
and
the
frame
sync.
separator.
The
line
oscillator
(which
is
free
running
at
approx.
14,6
kHz)
will
lock
itself
(PLL)
to
the
line
pulses
originating
from
the
incoming
video.
The
line
output
stage
is
capable
of
driving
the
line
output
transistor
7530
directly.
Via
3425
the
phase
of
the
line
output
stage
is
monitored.
When
the
line
output
is
getting
out
of
phase,
the
phase
detector
will
adjust
its
output,
so
the
line
output
will
get
in
phase
again.
As
the
VCC1
voltage
(9,8
Volt)
used
for
the
horizontal
and
vertical
oscillators
as
a
reference,
(is
precise
and
stable)
(using
2423
and
3423
as
1%
components)
it
is
not
necessary
to
have
a
line
oscillator
adjustment.
The
line
output
stage
of
7405
has
an
open
collector
therefore
3440,
3411
and
3409
are
added.
3431,
6430
and
6431
are
used
to
discharge
2490
during
the
down
going flank
of
pin
14
of 7405.
The
frame
oscillator
is
locked
to
the
vertical
pulses.
These
pulses
are
fed
into
the
vertical
power
stage,
which
is
capable
to
drive
the
vertical
deflection
coil
directly.
Via
feedback
3414,
3417
and
3413
the
amplitude
of
the
vertical
drive
is
obtained.
To
prevent
seeing
vertical
fly-back
lines,
the
VFB
is
generated
to
suppress
the
video
output
when
fly-back
lines
are
present.
Therefor
VFB
is
no
feedback
but
an
outgoing
signal
!!
The
fly-back
generator
is
essentially
a
switch
which
is
closed
when
a
Vertical
Feed-Back
pulse
(VFB)
is
needed.
e
During
the
scan
the
fly-back
generator
switch
is
open
so
2410
is
charged
to
approx.
+14V
via
6432.
e
During
the
fly-back
the
fly-back
generator
switch
is
closed
so
pin
3
of
7406
is
+14V.
As
2410
is
still
charged
to
+14V,
pin
7
of
7406
becomes
approx.
+28V
at the
beginning
of
the
fly-back.
e
During
the
fly-back
the
current
through
the
deflection
coil
must
quickly
come
to
“0”.
Due
to
the
inductive
reaction
of
the
deflection
coil
more
energy
is
needed
(therefor
the
+28V
is
used)

| Installation
When the configuration is altered, the system
must be scanned again. Therefore always
switch off the system by means of the rear
power switch when a camera or accessory is
added or removed. Only operating the power
save button is not sufficient.
Remark: Only the inputs to which cameras are connected
can be selected or used by the monitor. It is therefore
useless to connect an accessory to an input to which no
camera is connected.
Monitor
On the back of the monitor the following can be
connected:
Cameras
Connect the camera to one of the camera inputs at the
back of the monitor (fig. A-2).
Correctly directing the camera at the object will be
easier when the monitor is temporarily installed at the
camera site.
VCR
For the recording and reproducing of pictures and
sound a video recorder has to be connected to the
input and output (VCR-audio/video in/out) on the
back of the monitor (fig. A-2).
The VCR output can also be used to connect other
peripheral equipment. For example, a video printer for
hard copies.
Extra monitor
You can connect an extra monitor to the slave-output
(fig. A-2), by using the same twisted pair system
cable. The extra monitor gives exactly the same
picture and sound as the basic monitor.
In VCR mode, the slave monitor shows the image of
the last selected camera.
Alarm contact
The alarm contact (make (N.O.) and break (N.C.)) of
the monitor (fig. A-2) can, for instance, be used to
start up a video recorder, siren or telephone selector.
Cable
A 4-wire system cable (see specifications) is supplied
as standard.
For optimum picture and sound quality, a standard
dual 'twisted-pair' (telephone) cable should be used.
There is an extensive range of plugs and tools
available in the hobby and professional trade to extend
the cable. Always ensure that the connection is made
as shown in figure D (Page 19).
Caution: The plugs used for the observation system have
the same dimensions as standard telephone
plugs. Never connect a telephone to the camera
or system monitor.
The maximum distance that can be bridged (without a
cable extension adapter) between the monitor and the
cameras is 300 meters.

activate an (optional) action box. This can, for instance, be
used to open a door remotely. The action box remains
active for as long as the button is pressed.
Auto Sequence
The monitor switches slowly between the pictures (image +
sound) of the connected cameras.
Remark: The auto button is only functional when:
- camera mode is selected;
- the observation system is enlarged to at least two
cameras.
By pushing the auto button (fig. A-1) the automatic
sequence function is started. The automatic interval
sequence time (auto sequence time) can be adjusted
between 4 and 60 seconds on the back of the monitor
(fig. A-2).

A maximum of four cameras can be connected to the
monitor. Choosing a camera is done with the camera
selection keys 1, 2, 3 and 4 (fig. A-1), the appropriate LED
lights up.
VCR
With
this
button
(fig.
A-1)
the
monitor
is
switched
to
VCR
mode.
The
VCR-LED
will
light
up.
The

Next camera input
When closing the contacts of the next camera input
(fig. A-2), the system switches to the next available
camera (for future use).
Doorbell
When the doorbell button on the optional intercom box
is pushed, a buzzer will sound at the monitor, after which
the picture will be switched to the corresponding
camera. tf the automatic camera sequence is active, it
will be stopped. If the system operator does not react
within 1 minute to the warning signal by pushing any
button, the monitor will return to its previous status, or
the automatic camera sequence will continue.
Alarm
An alarm will sound if:
e there is a break in the camera line.
e this is detected by a camera alarm input or by an
alarm box (optional).
When an alarm sounds:
1) The system automatically switches to the
corresponding camera input.
2) The corresponding camera LED will start to blink.
3) The built-in alarm buzzer will be audible for 15
seconds.
4) The alarm contact (fig. A-2) is changed over for 3
minutes. The alarm contact can activate a video
recorder, siren or telephone selector. :
Alarm programming
If required, an alarm box in a particular camera line can
be disabled. This may be necessary to disconnect the
alarms of a door contact or movement detector during
the daytime. However, the cable detection remains
active at all times.
Push and hold the auto button together with the VCR
button.
The camera LED's on the monitor, the alarm function of
which is active, will light up. The auto LED will blink fast.
Push the corresponding camera selection button, the
alarm of which has to be switched on or off (LED on =
alarm on; LED off = alarm off).
If all camera lines are set, programming can be ended
by pushing the auto button. The monitor will return to
the status it had before programming.
Automatic alarm termination
After 3 minutes the monitor returns to the status it was in
before the alarm was sounding.
If the automatic camera sequence was active, it will be
continued. However, the corresponding camera LED
remains flashing for as long as the alarm line is active
(alarm detector is still active) or the camera line is still
cut.
Premature (within 3 minutes) alarm
termination
The alarm output (fig. A-2) will be de-activated by
switching off the aiarm. See alarm programming above.
Pressing any key on the control panel of the monitor
within 15 seconds will end the alarm sound only.
Alarm priority
A new alarm always gets priority. The monitor will
always switch to the camera of the last-received alarm
but the LED(s) of each previously received alarm blink
faster.
| Tips for maintenance
Ventilation
Avoid overheating the system monitor by ensuring to it
that the ventilation openings on the top of the monitor
remain uncovered. Do not place the monitor in the
immediate vicinity of a source of heating.
Cleaning
You can clean the system monitor with a moist, fluff-free
cloth or chamois leather cloth.
The outside of the camera can be cleaned with a moist,
fluff-free cloth or chamois leather cloth.
When cleaning the objective a special lens cleaning cloth
should be used. Do NOT use cleaning fluids that contain
alcohol, methylated spirit, ammonia, etc..
