ENGLISH VERSION

The lightning flash with arrowhead sym­bol, within an equilateral triangle, is
interned to alert the user to the pres­ence of uninsulated "dangerous volt­age" within the product's enclosure that
may be of sufficient magnitude to con­stitute a risk of electric shock to per­sons.

Cet appareil est conforme aux prescriptions de la
directive 87/308/C.E.E. (concernant les interférences
radio).

Dit modelis onderworpen aan de EEG-richtlijn (ter
voor-koming van radio-interferentie) 87/308/EGG.

Denne model opfylder EF direktiv 87/308/EF (for for­ebyggelse af radiointerferens).

Este modelo cumple con la norma EC (para interfer­encias de radio 87/308/EEC).

La Società PANASONIC ITALIA S.p.A., importatrice di
questo prodotto, dichiara che questo apprarecchio è
conforme alle disposizioni della direttiva
C.E.E./87/308 (D.M. 13 aprile 1989).

IMPORTANT

The wires in this mains lead are coloured in accordance with the following
code.

Green-and-yellow: Earth
Blue: Neutral
Brown: Live

As the colours of the wire in the mains lead of this appliance may not
correspond with the coloured markings identifying the terminals in your
plug, proceed as follows.

The wire which is coloured green-and-yellow must be connected to
the terminal in the plug which is marked with the letter E or by the earth
symbol or coloured green or green-and-yellow.

The wire which is coloured blue must be connected to the terminal in
the plug which is marked with the letter N or coloured black.

The wire which is coloured brown must be connected to the terminal
in the plug which is marked with the letter L or coloured red.

How to replace the fuse

Open the fuse compartment with
a screwdriver and replace the fuse
and fuse cover.

THIS APPARATUS MUST BE EARTHED.

To ensure safe operation the three-pin plug supplied must be inserted
only into a standard three-pin power point which is effectively earthed
through the normal household wiring. Extension cords used with the
equipment must be three-core and be correctly wired to provide con­nection to earth. Wrongly wired extension cords are a major cause of
fatalities.
The fact that the equipment operates satisfactorily does not imply that
the power point is earthed and that the installation is completely safe.
For your safety, if in any doubt about the effective earthing of the
power point, consult a qualified electrician.

This apparatus was produced to BS 800:1987.

This model conforms of the EC directive (for radio interference)
87/308/EEC.

circuit Video Monitor especially designed for sur­veillance and studio applications.
WV-BM500 features a 5” screen (diagonal actual
visual size) and produces sharp, black-and-white
pictures with horizontal resolution of more than 700
lines at center.
Front mounted controls permit fast picture adjust­ment. Standard BNC-type input and output con­nectors enables WV-BM500 to be used with other
CCTV monitors or Panasonic Video Tape
Recorder.

FEATURES

• 5’’ screen (diagonal actual visual size).

• Horizontal resolution 700 lines at center.

• Short H. AFC time constant for VTR playback.

• Bridging input and output connectors for video
and composite sync.

• DC restoration.

• Internal and External Sync mode.

• By using the Optional Rack Angle Bracket WV­Q64, rack mounting is available.

PRECAUTIONS

• This unit is designed for indoor use. Operable
ambient temperature range must not exceed
beyond

−10°C - +50°C (14°F - 122°F), and permis­sible humidity is less than 90%. Avoid using the
monitor under direct sunIight.

• The input power source is 220 - 240V AC 50 Hz .

• Do not block the ventilation slots on the rear panel
and side cover.

• When mounting the Model WV-BM500 in an EIA

CONNECTIONS

Power Cable

1. Keep the camera Power switched OFF during
installation.

2. Connect the Power Cord (16) to a 50 Hz grounded
electrical outlet 220-240V AC .

Video Cable

1. Use the RG-59/U (3C-2V), RG-6/U (5C-2V). RG­11/U (7C-2V) or RG-15/U (10C-2V) coaxial cable.

2. Up to 10 monitors can be hooked up in this config­uration before signal loss occurs. Total cable
length should not exceed 500 feet (150m).

3. Wiring Precautions

• Do not bend coaxial cable into a curve whose
radius is smaller than 10 times of its diameter.

• Never crush or pinch the cable
All these will change the impedance of the cable
and cause poor picture quality

External Sync

When a non-composite video signal is connected to
the monitor, it will be necessary to connect an external
composite sync signal to the monitor.

1. Connect the Sync Input Connector (14) on the
video monitor to the sync signal source by means
of a 75Ω coaxial cable.

2. Set the Sync Selector Switch (13) at EXT position.

NOTE:

1. Non-composite video signal is a signal without
sync.

2. External sync should be composed of mixed H.
Sync and V. sync signals, not H. and V. drive
pulse signals. Composite Sync Level:

4.0 Vp-p (2.0 Vp-p − 5.0 Vp-p)

SYSTEM CONNECTION

1. Single Monitor Connection

2. Multiple Monitor Connection

Internal Sync Connection

• Connect the Video Input Connector (11) on the

monitor to the Video Out Terminal of cameras with
75-ohm coaxial cables.

External Sync Connection

• When a non-composite video signal is connected

to the video monitor, it must also have an external
composite SYNC signal connected to the video
monitor.

• Set the Sync Selector Switch (13) at EXT position.

• Loop through connection of sync signal is the

same as the case of Video Signal.
