SAFETY PRECAUTIONS
GENERAL GUIDELINES
1. When servicing, observe the original lead dress. If a
short circult Is found, replace all parts which have been
overheated or damaged by the short circuit.
2. After servicing, see to Kt that all the protective devices
such as insulation barriers, insulation papers shields are
propery Installed.
3. After servicing, make the following leakage current
checks to prevent the customer from being exposed to
shock hazards.
LEAKAGE CURRENT COLD CHECK
1. Unplug the AC cord and connect a jumper between the
two prongs on the plug.
2. Measure the resistance value, with an ohm meter, be-
tween the Jumpered AC plug and each exposed metallic
cabinet part on the equipment such as screwheads con-
nectors, control shalts,etc. Whon the exposed metallic
part has a return path to the chassis, the roading should
be betwoon 1M ohm and 5.2 M ohm.
When the exposed metal does not have a return path to
the chassis, the reading must be 00,
LEAKAGE CURRENT HOT CHECK
(See Figure 1)
1. Plug the AC cord directly Into the AC outlet. Do not use
an isolation transformer for this check.
2. Connect a 1.5k ohm, 10 waits resistor, In parallel with a
0.15uF capacitor, between each exposed metallic part
on the set and a good earth ground such as a water pipe,
as shown in Figure 1.
3. Use an AC voltmeter, with 1000 ohms/volt or more sen-
sitivity, to measure the potential across the resistor.
4. Check each exposed metallic pan, and measure the
voltage at each point.
5. Reverse the AC plug in the AC outlet repeat each of the
above measurements.
6. The potential at any point should not exceed 0.75 volts
RMS. A leakage current tester (Simpson Model 229
equivalent) may be used to make the hot checks, leak-
age current must not exceed 1/2 milliamp. In case a
measurement is outside of the limits specified, there is a
possibllity of a shock hazard, and the equipment should
be repaired and rechecked before it is returned to the
customer.

(EARTH GROUND)
ELECTROSTATICALLY
SENSITIVE (ES) DEVICES
Some semiconductor (solid state) devices can be dam-
aged easily by static electricity. Such components com-
monly are called Electrostatically Sensitive (ES) Devices.
Examples of typical ES devices are integrated circults and
some field-effect transistors and semiconductor chip
components. The following techniques should be used to
help reduce the incidence of component damage caused
by static electricity.
1. Immediately before handling any semiconductor com-
ponent or semiconductor-equipped assembly, drain off
any electrostatic charge on your body by touching a
known earth ground,
Alternatively, obtain and wear a commercially avaliable
discharging wrist strap device, which should be re-
moved for potential shock reasons prior to applying
power to the unit under test.
2. After removing an electrical assembly equipped with ES
devices, place the assembly on a conductive surface
such as aluminum foil, to prevent electrostatic charge
buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or un-
solder ES devices.
4, Use only an anti-static solder removal device classified
as anti-static can generate electrical charges sufficient
to damage ES devices,
5. Do not use freon-propelled chemicals. These can gener-
ate electrical charges sufficlent to damage ES devices.
6. Do not remove a replacement ES device from its protec-
live package untillmmediately before you are teady to
Install tt. (Most replacementES devices are packaged
with leads eletcrically shorted together by conductive
foam, aluminum foil or comparable conductive mate-
rial).
7. immediately before removing the protective material
from the leads of replacement ES device, touch the
protective material to the chassis or circuit assembly into
which the device will be installed.
CAUTION : Be sure no power Is applied to the chassis or
circult, and observe all otner asfety precautions.
8. Minimize bodily motions when handling unpackaged
replacement ES devices. (Otherwise harmless motion
such as the brushing together of your clothes fatoric or
the lifting of your foot from a carpeted floor can generate
Static electricity sufficlent to damage an ES device).

OPERATING INSTRUCTIONS ied
Caution for AC Mains Lead
FOR YOUR SAFETY PLEASE READ THE FOLLOWING TEXT CAREFULLY.
FOR U.K. ONLY
Tims appliance is supplied with a moulded three pin
mains plug for your safety and convenience.
A 5 amp fuse is fitted in this plug.
Should the fuse need to be replaced please ensure
that the replacement fuse has a rating of 5 amps and
that it ls approved by ASTA or 8S! to BS1362. Check
for the ASTA @ mark or the BSI mark &@ on the
body of the fuse.
if the plug contains a removable fuse cover you must
ensure that it is refitted when the fuse is replaced.
if you lose the tuse cover the plug must not be used
until a reptacement cover is obtained.
A replacement fuse cover can be purchased from your
local Panasonic Dealer.
1F THE FITTED MOULDED PLUG IS UNSUITABLE FOR
THE SOCKET OUTLET IN YOUR HOME THEN THE
FUSE SHOULD BE REMOVED AND THE PLUG CUT
OFF AND DISPOSED OF SAFELY.
THERE IS A DANGER OF SEVERE ELECTRICAL
SHOCK IF THE CUT OFF PLUG IS INSERTED INTO
ANY 13 AMP SOCKET.
if a new plug ts to be fitted please observe the wiring
code as shown below.
it in any doubt please consult a qualified electrician.
IMPORTANT: The wires in this mains lead are coloured
in accordance with the following code:
Blue: Neutral
Brown: Live
As the colours of the wires in the mains lead of this
appliance may not correspond with the coloured mark-
ings identifying the terminals in your plug, proceed as
follows:
¢ The wire which is coloured BLUE must be connected
to the terminal in the plug which is marked with the
fetter N or coloured BLACK.
e The wire which is coloured BROWN must be con-
nected to the terminal in the piug which is marked
with the letter L or coloured RED.
e Under no circumstances should either of these wires
be connected to the terminal in the plug which is marked
with the letter E or by the Earth symbol | .
How to replace the fuse
1. Open the fuse compartment with a screwdriver.
Lithium Battery
Warning
The lithium battery in this equipment must only be
replaced by qualified personnel. When necessary,
contact your local Panasonic supplier.
“The lithium battery is a critical component (type num-
ber VL2330/1HF manufactured by Panasonic.)
it must never be subjected to excessive heat or dis-
charge. It must therefore only be fitted in equipment
designed specifically for its use.
Replacement batteries must be of the same type and
manufacturer. They must be fitted in the same manner
and location as the original battery, with the correct
polarity connections observed.
Do not attempt to re-charge the old battery or re-use
it for any other purpose. It should be disposed of in
waste products destined for burial rather than incin-
eration.”

Notes on operation
¢ This unit is designed with the NV-E180 cassette tape as a reference.
Depending on the type of video cassette used, the recordable time will differ.
Sound can be recorded in all time modes.
The 12- and 24-hour modes are time lapse modes. Pictures are recorded with frames skipped to enable lengthy
recording and playback.
A tape recorded in a time lapse (12-/24-hour) mode can be played back in quick motion in the 3-hour mode.
A tape recorded in the 3-hour mode can be played back in slow motion using the time lapse (12-/24-hour)
mode.
A tape recorded in the 6-hour (or 3-hour) mode cannot be played back in the 3-hour (or 6-hour) mode.
When a tape recorded on the 6-hour mode is played back in another mode, colour programme is played back
in black and white, but this is not a malfunction.
Selecting the cassette tape
The unit is designed as a product required to exhibit high reliability in surveillance, security, monitoring, etc. In
order to maintain its recording reliability, it is recommended that the Panasonic video tapes listed below be used.
