IMPORTANT SAFEGUARDS
CAUTION:
Please read and retain for your safety.
Electrical energy can perform many useful functions. This TV
set has been engineered and manufactured to assure your
personal safety. But improper use can result in potential
electrical shock or fire hazards. In order not to defeat the
safeguards incorporated in this TV set, observe the following
basic rules for its installation, use and servicing.
And also follow all warnings and instructions marked on your
TV set.
INSTALLATION
1 Your TV set is equipped with a polarized AC line plug (one
blade of the plug is wider than the other).
This safety feature allows the plug to fit into the power
outlet only one way. Should you be unable to insert the
plug fully into the outlet, try reversing the plug.
Should it still fail to fit, contact your electrician.
2 Operate the TV set only from a power source as indicated
on the TV set or refer to the operating instructions for this
information. If you are not sure of the type of power supply
to your home, consult your TV set dealer or local power
company. For battery operation, refer to the operating
instructions.
3 Overloaded AC outlets and extension cords are danger-
ous, and so are frayed power cords and broken plugs.
They may result in a shock or fire hazard. Call your service
technician for replacement.
4 Do not allow anything to rest on or roll over the power
cord, and do not place the TV set where power cord is
subject to traffic or abuse. This may result in a shock or
fire hazard.
5 Do not use this TV set near water — for example, near a
bathtub, washbowl, kitchen sink, or laundry tub, in a wet
basement, or near swimming pool, etc.

20 Note to CATV system installer.
This reminder is provided to call the CATV system installer’s
attention to Article 820-40 of the NEC that provides
guidelines for proper grounding and, in particular, specifies
that the cable ground shall be connected to the grounding
system of the building, as close to the point of cable entry
as practical.
antenna system is grounded so as to provide some pro t e c t i o n
against voltage surges and built-up static charges. Section 810
of the National Electrical Code provides information with re s p e c t
to proper grounding of the mast and supporting stru c t u re ,
g rounding of the lead-in wire to an antenna discharge unit, size
of grounding conductors, location of antenna discharge unit,
connection re q u i rements for the grounding electro d e .
7 An outside antenna system should not be located in the
vicinity of overhead power lines or other electric light or
power circuits, or where it can fall into such power lines or
circuits. When installing an outside antenna system, extreme
care should be taken to keep from touching such power
lines or circuits as contact with them might be fatal.
EXAMPLE OF ANTENNA GROUNDING
AS PER NATIONAL ELECTRICAL CODE

PRECAUTIONS ABOUT VIDEO
Before operating the video unit, please read the precautions on this page.
Precautions for Recording TV
Programs
About Copyright
The recordings you make from TV programs or prerecorded tapes cannot be used without permission
from the copyright holders, except when they are
used solely for personal enjoyment.
Trial Recording Before Making Important
Recordings
Make a trial recording before an important program
to be sure that you can record and playback audio
and video properly.
Disclaimer:
JVC assumes no liability for failure to record or
playback audio and video properly with this unit.
Precautions About Video Cassettes
Keep these points in mind while working with video
cassettes.
Recording
• If you record on a previously recorded tape, the
original content will be automatically erased.
• Video cassettes cannot be reversed or “flipped
over” like audio cassettes.
Handling Cassettes Properly
• To store cassettes, place them inside their cases.
The cases should then be stored vertically.
• Do not drop cassettes, or give them any other
hard shock.
• Rewind cassettes before storing.
• Do not repeatedly load and unload tapes without
running them in between.
Do Not Store in the Following Places
• Exposed to direct sunlight or near a heating
device.
• Exposed to excessive humidity, smoke, or dust.
• Near a strong magnet (including speakers).
Prevent Accidental Erasur e
Remove the small plastic tab at the rear of the
cassette. Without this tab, the cassette cannot be
used for recording. It is recommended that you
remove the tabs from important cassettes to prevent
accidental erasure. To record on a cassette whose
tabs have ben removed, cover the tab hole with two
layers of adhesive tape.
Precautions About Moistur e
Condensation
What is Moisture Condensation?
When you put cold water into a glass, water droplets
form on its surface. This phenomenon is called
moisture condensation.
If Moisture Condensation Occurs
The video unit may fail to operate, or may operate
erratically potentially damaging the unit and video
cassettes.
When Does Condensation Occur?
• When equipment is moved from a colder to a
warmer place.
• Immediately after a room heater is started.
• When the unit is exposed to a cold air flow (like
from an air conditioner)
• In high humidity or when steam is present.
To Prevent Condensation
• Wait about an hour before operating the unit so
that it can become accustomed to the room
conditions.
• Provide proper ventilation.
If the unit fails to operate or operates poorly and you
think condensation may be the cause, turn the unit’s
power off and wait a few hours before trying to
operate the unit again.
Enjoying Clear Video
Cleaning the Video Heads
After a long, or frequent use, the video heads inside
the unit may become dirty, possibly resulting in poor
picture quality. To prevent this from happening, it is
recommended you clean the unit frequently with a
head cleaning cassette (TCL-2 or 3, sold
separately).
If Video Quality is Still Poor After Cleaning
Try cleaning the unit two or three times instead of
just once. If the repeated cleaning still fails to
produce better picture quality, an internal
malfunction may be the cause. Call your local dealer
for servicing.

CONNECTIONS CHECKLIST — READ ME FIRST!
The Connections Checklist — Read Me First! section of this guide is a list of ideas to keep in mind
when you set out to perform your connections. It is designed to help us not-so-technicallyadvanced individuals. If you read this section, and can’t identify the plugs, connectors, and
components you have, do not be afraid to seek help.
1) Always refer to the connection instructions in the user’s
guide for your components first! The manufacturer will
provide the most detailed information about their products.
2) Know your jacks and plugs — most are color coded:
• Yellow plugs are Video connections

A/V input plug
• White or black plugs are Left Audio (Mono) connections (if your camcorder is a stereo model, use a
stereo-to-monaural conversion cable to connect to the
Combo unit. Conversion cables may be purchased
separately.)
3) Perform one hookup at a time. If you have many
accessories to connect, make sure each connection is
correct by checking to see that it works properly before
attempting the next connection.
4) Unplug the power cord between each connection.
