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
described 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
understand that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE.
Funai could not possibly know, evaluate and advice the service trade of all
conceivable 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 procedure or tool which is not recommended by Funai must first use
all precautions thoroughly so that neither his safety nor the safe operation
of the equipment will be jeopardized by the service method selected.

CAUTION !
Fixed voltage ( or Auto voltage selectable ) power supply circuit is used in this unit.
If Main Fuse (F1001) is blown, 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.

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
3
(K=10
3. Resistor wattages are 1/4W or 1/6W unless otherwise specified.
4. All capacitance values are indicated in µF

specified.

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

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. Wire Connectors
(1) Prefix symbol "CN" means "connector" (can disconnect and reconnect).
(2) Prefix symbol "CL" means "wire-solder holes of the PCB" (wire is soldered directly).
