PRECAUTIONS

1.1 SAFTY PRECAUTIONS

Prior to shipment from the factory, JVC products are strictly inspected to conform with the recognized product safety and electrical codes of the countries in which they are to be sold.However,in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced.
1.1.1 Precautions during Servicing
(1) Locations requiring special cauti on are denoted by labels
and inscriptions on the cabinet, chassis and certain parts of the product.When performing service, be sure to read and comply with these and other cautionary notices appearing in the operation and service manuals.
(2) Parts identified by the symbol and shaded ( ) parts
are critical for safety. Replace only with specified part numbers.
NOTE :
Parts in this category also include those specified to comply with X-ray emission standards for products using cathode ray tubes and those specified for compliance with various regulations regarding spurious radiation emission.
(3) Fuse replacement caution notice.
Caution for continued protection against fire hazard. Replace only with same type and rated fuse(s) as specified.
(4) Use specified internal wiring. Note especially:
• Wires covered with PVC tubing
• Double insulated wires
• High voltage leads
(5) Use specified insulating materials for hazardous live parts.
Note especially:
• Insulation Tape
• PVC tubing
•Spacers
• Insulation sheets for transistors
•Barrier
(6) When replacing AC primary side compon ents (transformers,
power cords, noise blocking capacitors, etc.) wrap ends of wires securely about the terminals before soldering.
emission. Consequently, when servicing these products, replace the cathode ray tubes and other parts with only the specified parts. Under no circumstances attempt to modify these circuits.Unauthorized modification can increase the high voltage value and cause X-ray emission from the cathode ray tube.
(12) Crimp type wire connectorIn such cases as when replacing
the power transformer in sets where the connections between the power cord and power trans former primary lead wires are performed using crimp type connectors, if replacing the connectors is unavoidable, in order to prevent safety hazards, perform carefully and precisely according to the following steps.
Connector part number :E03830-001
Required tool : Connector crimping tool of the proper type which will not damage insulated parts.
Replacement procedure
a) Remove the old connector by cutting the wires at a
point close to the connector.Important : Do not reuse a connector (discard it).
cut close to connector
Fig.1-1-3
b) Strip about 15 mm of the insulati on from the ends
of the wires. If the wires are stranded, twist the strands to avoid frayed conductors.
15 mm
Fig.1-1-4
c) Align the lengths of the wires to be connected.
Insert the wires fully into the connector.
Metal sleeve
Fig.1-1-1
(7) Observe that wires do not contact heat producing parts
(heatsinks, oxide metal film resistors, fusible resistors, etc.)
(8) Check that replaced wires do not contact sharp edged or
pointed parts.
(9) When a power cord has been replaced, check that 10-15
kg of force in any direction will not loosen it.

3.1 BEFORE ASSEMBLY AND DISASSEMBLY

3.1.1 Precautions
• Be sure to disconnect the power supply unit prior to mounting and soldering of parts.
• Prior to removing a component part that needs to disconnect its connector(s) and its screw(s), first disconnect the wire(s) from the connector(s), and then remove the screw(s).
• When connecting/disconnecting wires, pay enough attention not to damage the connectors.
• When inserting the flat wire to the connector, pay attention to the direction of the flat wire.
• Be careful in removing the parts to which some spacer or shield is attached for reinforcement or insulation.
• When replacing chip parts (especially IC parts), first remove the solder completely to prevent peeling of the pattern.
• Tighten screws properly during the procedures. Unless specified otherwise, tighten screws at a torque of 0.118N
·cm). However, 0.118N·m (1.2kgf·cm) is a value at the

5.2 TAKE OUT CASSETTE TAPE

(1) Remove the Power Unit (battery or DC code) from the set. (2) Remove one screw, and remove a plate (ADJ).
NOTE:
For more efficient operation, loosen and move the grip belt prior to the procedure (2).
(3) Open the CASSETTE COVER till it is completely opened
and fixed. (4) Attach a PVC tape as shown in the figure.
NOTE:
Be careful of cassette tape damage caused because the CASSETTE HOUSING ASSEMBLY is moved upward at the unloading end (EJECT mode).
(5) To set the SLIDE DECK ASSEMBLY to the unloading end,
apply DC 3V to the electrode (terminal) on the top surface
of the LOADING MOTOR ASSEMBLY that is seen through
a hole under the plate removed in the procedure (2).
NOTE:
Be careful not to attach grease or a similar substance to the surface of the cassette tape on the tape transport system.
(6) Wind the cassette tape by directly turning the REEL DISK
ASSEMBLY (SUP) from the backside of the SLIDE DECK
ASSEMBLY by using a sharp tool (Chip IC replacement
tool). (7) Confirm that the cassette tape is completely woun d, and
then peel off the PVC tape from the CASSETTE HOUSING
ASSEMBLY and take out the cassette tape.
NOTE:
To confirm that the cassette tape is completely wound, confirm that one REEL DISK ASSEMBLY (TU) rotates as you rotate the other REEL DISK ASSEMBLY (SUP).
(8) Make sure that grease or a similar substance is not
attached to the surface of the tape taken out in the
procedure (7). Similarly, also make sure that grease or a
similar substance is not attached on the MECHANISM
ASSEMBLY, especially the tape transport system.

5.3 EMERGENCY DISPLAY

Example (in case of the error number E01):
Whenever some abnormal signal is input to the syscon CPU, an error number (E01, as an example) is displayed on the LCD monitor or (in the electronic view finder).In every error status, such the message as shown below alter nately appear over and
E01 UNIT IN SAFEGUARD MODE
over.
• In an emergency mode, all operations except turning on/off the POWER switch are ineffectual.
LCD display Emergencymode Details Possible cause
E01 LOADING In the case the encoder position is
not shifted to the next point though the loading motor has rotated in the loading direction for 4 seconds or more. This error is defined as [E01].
E02 UNLOADING In the case the encoder position is
not shifted to the next point though the loading motor has rotated in the unloading direction for 4 seconds or
1. The mechanism is locked during mode shift.
2. The mechanism is locked at the mechanism loading end, because the encoder position is skipped during mechanism mode shift.
3. No power is supplied to the loading MDA.
1. The mechanism is locked during mode shift.
2. The mechanism is locked at the mechanism loading end, because the encoder position is skipped during mechanism mode shift.
more. This error is defined as [E02].
E03 TU & SUP REEL FG In the case no REEL FG is
produced for 4 seconds or more in the capstan rotation mode after loading was complete, the mechanism mode is shifted to STOP with the pinch roller set off. This error is defined as [E03].However, no REEL EMG is detected in the SLW/STILL mode.
1. The idler gear does not engage with the reel disk well.
2. Though the idler gear and reel disk are engaged with each other, the tape is not wound because of overload to the mechanism.
3. No FG pulse is output from the reel sensor.
4. No power is supplied to the reel sensor.
5. Tape transport operation takes place with a cassette having no tape inside.
6. The tape slackens and no pulse is produced until the slack is taken up and the tape comes into the normal status.
E04 DRUM FG In the case there is no DRUM FG
input in the drum rotation mode for 4 seconds or more. This error is defined as [E04], and the mechanism mode is shifted to STOP with the pinch roller set off.
1. The drum cannot be started or drum rotation is stopped because tape transport load is too high.
1) Tape tension is extremely high.
2) The tape is damaged or soiled with grease, etc.
2. The DRUM FG signal is not received by the syscon CPU.
1) Disconnection in the middle of the signal line.
2) Failure of the DRUM FG pulse generator (hall
element).
3. No drum control voltage is supplied to the MDA.
4. No power is supplied to the DRUM MDA.
E05 - - ­E06 CAPSTAN FG In the case no CAPSTAN FG is
produced in the capstan rotation mode for 2 seconds or more. This error is defined as [E06], and the mechanism mode is shifted to STOP with the pinch roller set off.However, no CAPSTAN EMG is detected in the STILL/FF/REW mode.
1. The CAPSTAN FG signal is not received by the syscon CPU.
1) Disconnection in the middle of the signal line.
2) Failure of the CAPSTAN FG pulse generator (MR
element).
2. No capstan control voltage is supplied to the MDA.
3. The capstan cannot be started or capstan rotation is stopped because tape transport load is too high.
1) Tape tension is extremely high. (Mechanical locking)
2) The tape is damaged or soiled with grease, etc. (Tape
tangling occurs, etc.)
