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.

IMPORTANT PRODUCT
SAFETY INSTRUCTIONS
Electrical energy can perform many useful functions. But
improper use can result in potential electrical shock or fire
hazards. This product has been engineered and manufactured
to assure your personal safety. In order not to defeat the built-in
safeguards, observe the following basic rules for its installation,
use and servicing.
ATTENTION:
Follow and obey all warnings and instructions marked on your
product and its operating instructions. For your safety, please
read all the safety and operating instructions before you operate
this product and keep this booklet for future reference.
INSTALLATION
1. Grounding or Polarization
(A) Your product may be equipped with a polarized alternating-
current line plug (a plug having one blade wider than the
other). This plug will fit into the power outlet only one way.
This is a safety feature.
If you are unable to insert the plug fully into the outlet, try
reversing the plug. If the plug should still fail to fit, contact
your electrician to replace your obsolete outlet. Do not
defeat the safety purpose of the polarized plug.
(B) Your product may be equipped with a 3-wire grounding-type
plug, a plug having a third (grounding) pin. This plug will
only fit into a grounding-type power outlet. This is a safety
feature.
If you are unable to insert the plug into the outlet, contact
your electrician to replace your obsolete outlet. Do not
defeat the safety purpose of the grounding-type plug.
2. Power Sources
Operate your product only from the type of power source
indicated on the marking label. If you are not sure of the type of
power supply to your home, consult your product dealer or
local power company. If your product is intended to operate
from battery power, or other sources, refer to the operating
instructions.
3. Overloading
Do not overload wall outlets, extension cords, or integral
convenience receptacles as this can result in a risk of fire or
electric shock.
4. Power Cord Protection
Power supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against
them, paying particular attention to cords at plugs, convenience
receptacles, and the point where they exit from the product.
5. Ventilation
Slots and openings in the cabinet are provided for ventilation.
To ensure reliable operation of the product and to protect it
from overheating, these openings must not be blocked or
covered.
· Do not block the openings by placing the product on a bed,
sofa, rug or other similar surface.
· Do not place the product in a built-in installation such as a
bookcase or rack unless proper ventilation is provided or the
manufacturer's instructions have been adhered to.
6. Wall or Ceiling Mounting
The product should be mounted to a wall or ceiling only as
recommended by the manufacturer.

INSTRUCTIONS
1. Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the
product, be sure the antenna or cable system is grounded so as
to provide some protection against voltage surges and built-up
static charges. Article 810 of the National Electrical Code,
ANSI/NFPA 70, provides information with regard to proper
grounding of the mast and supporting structure, grounding of
the lead-in wire to an antenna discharge unit, size of grounding
connectors, location of antenna discharge unit, connection to
grounding electrodes, and requirements for the grounding
electrode.
2. Lightning
For added protection for this product during a lightning storm,
or when it is left unattended and unused for long periods of
time, unplug it from the wall outlet and disconnect the antenna
or cable system. This will prevent damage to the product due to
lightning and power-line surges.
3. Power Lines
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.

ABOUT HEAD CLEANING
After an extended period of use, the video heads can become dirty, resulting in a loss of picture or sound during
playback. If this happens, clean the video heads by using the optional cleaning tapes.
Symptoms of dirty video heads:
The picture is not clear, or does not appear.
There is no sound.
Mosaic (block) noise appears in the picture.
Black or mosaic horizontal stripes appear in the
picture.
The picture stops (as if the tape is paused).
A blank black or blue screen appears.
The picture is fuzzy. (VHS playback)
Use a cleaning tape designed specifically for D-VHS video heads (JVC D-VHS video head cleaner DFC-2) to clean the video heads.
In order to avoid misoperation, set "NAVIGATION" to "OFF" (
pg. 43).
Follow the instructions that are provided with the cleaning tape.
If you still do not get a clear picture after using a cleaning tape:
The heads may be worn. Contact your nearest JVC dealer.
During VHS playback, if there is a tracking problem, the picture may appear fuzzy. Adjust the tracking manually (
pg. 23).
