IMPORTANT SAFETY NOTICE
Proper service and repair is important to the safe, reliable operation of all
Funai Equipment. The service procedures recommended by Funai and de-
scribed in this service manual are effective methods of performing service
operations. Some of these service special tools should be used when and
as recommended.
It is important to note that this service manual contains various CAUTIONS
and NOTICES which should be carefully read in order to minimize the risk of
personal injury to service personnel. The possibility exists that improper
service methods may damage the equipment. It also is important to under-
stand that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. Funai
could not possibly know, evaluate and advice the service trade of all con-
ceivable ways in which service might be done or of the possible hazardous
consequences of each way. Consequently, Funai has not undertaken any
such broad evaluation. Accordingly, a servicer who uses a service proce-
dure or tool which is not recommended by Funai must first use all precau-
tions thoroughly so that neither his safety nor the safe operation of the
equipment will be jeopardized by the service method selected.

SCHEMATIC DIAGRAMS / CBA’S AND TEST POINTS
Standard Notes
WARNING
Many electrical and mechanical parts in this chassis
have special characteristics. These characteristics
often pass unnoticed and the protection afforded by
them cannot necessarily be obtained by using
replacement components rated for higher voltage,
wattage, etc. Replacement parts that have these
special safety characteristics are identified in this
manual and its supplements; electrical components
having such features are identified by the mark “#” in
the schematic diagram and the parts list. Before
replacing any of these components, read the parts list
in this manual carefully. The use of substitute
replacement parts that do not have the same safety
characteristics as specified in the parts list may create
shock, fire, or other hazards.
Notes:
1. Do not use the part number shown on these
drawings for ordering. The correct part number is
shown in the parts list, and may be slightly
different or amended since these drawings were
prepared.
2. All resistance values are indicated in ohms
(K = 103, M = 106).
3. Resistor wattages are 1/4W or 1/6W unless
otherwise specified.
4. All capacitance values are indicated in µF
(P = 10-6 µF).
5. All voltages are DC voltages unless otherwise
specified.

LIST OF CAUTION, NOTES, AND SYMBOLS USED IN THE SCHEMATIC DIAGRAMS ON
THE FOLLOWING PAGES:
1. CAUTION:
FOR CONTINUED PROTECTION AGAINST FIRE HAZARD, REPLACE ONLY WITH THE
SAME TYPE FUSE.
ATTENTION: POUR UNE PROTECTION CONTINUE LES RISQES D'INCELE N'UTILISER
QUE DES FUSIBLE DE MÊME TYPE.
RISK OF FIRE-REPLACE FUSE AS MARKED.
2. CAUTION:
Fixed Voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F1001) is blown, first check to see that all components in the power supply circuit are not
defective before you connect the AC plug to the AC power supply. Otherwise it may cause some components
in the power supply circuit to fail.
3. Note:
1. Do not use the part number shown on the drawings for ordering. The correct part number is shown in the
parts list, and may be slightly different or amended since the drawings were prepared.
2. To maintain original function and reliability of repaired units, use only original replacement parts which are
listed with their part numbers in the parts list section of the service manual.
4. Mode: SP/REC
5. Voltage indications for PLAY and REC modes on the schematics are as shown below:

SPECIFICATIONS
< VCR Section >
Note: Nominal specs represent the design specs. All units should be able to approximate these – some will exceed
and some may drop slightly below these specs. Limit specs represent the absolute worst condition that still might
be considered acceptable; In no case should a unit fail to meet limit specs.
