SECTION 1
PRECAUTIONS
1.1 SAFETY 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 caution 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 components (transformers,
power cords, noise blocking capacitors, etc.) wrap ends of
wires securely about the terminals before soldering.
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.
Fig.1-1-2
(10) Also check areas surrounding repaired locations.
(11) Products using cathode ray tubes (CRTs)In regard to such
products, the cathode ray tubes themselves, the high
voltage circuits, and related circuits are specified for
compliance with recognized codes pertaining to X-ray
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).
Fig.1-1-3
b) Strip about 15 mm of the insulation from the ends
of the wires. If the wires are stranded, twist the
strands to avoid frayed conductors.
Fig.1-1-4
c) Align the lengths of the wires to be connected.
Insert the wires fully into the connector.
Fig.1-1-5
d) As shown in Fig.1-1-6, use the crimping tool to crimp
the metal sleeve at the center position. Be sure to
crimp fully to the complete closure of the tool.
Fig.1-1-6
e) Check the four points noted in Fig.1-1-7.

1.1.2 Safety Check after Servicing
Examine the area surrounding the repaired location for damage
or deterioration. Observe that screws, parts and wires have been
returned to original positions, Afterwards, perform the following
tests and confirm the specified values in order to verify
compliance with safety standards.
(1) Insulation resistance test
Confirm the specified insulation resistance or greater
between power cord plug prongs and externally exposed
parts of the set (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks,
earphone jacks, etc.).See table 1 below.
(2) Dielectric strength test
Confirm specified dielectric strength or greater between
power cord plug prongs and exposed accessible parts of
the set (RF terminals, antenna terminals, video and audio
input and output terminals, microphone jacks, earphone
jacks, etc.). See Fig.1-1-11 below.
(3) Clearance distance
When replacing primary circuit components, confirm
specified clearance distance (d), (d') between soldered
terminals, and between terminals and surrounding metallic
parts. See Fig.1-1-11 below.
Fig.1-1-8
(4) Leakage current test
Confirm specified or lower leakage current between earth
ground/power cord plug prongs and externally exposed
accessible parts (RF terminals, antenna terminals, video
and audio input and output terminals, microphone jacks,
earphone jacks, etc.).
Measuring Method : (Power ON)Insert load Z between
earth ground/power cord plug prongs and externally
exposed accessible parts. Use an AC voltmeter to
measure across both terminals of load Z. See Fig.1-1-9
and following Fig.1-1-12.
Fig.1-1-9
(5) Grounding (Class 1 model only)
Confirm specified or lower grounding impedance between
earth pin in AC inlet and externally exposed accessible
parts (Video in, Video out, Audio in, Audio out or Fixing
screw etc.).Measuring Method:
Connect milli ohm meter between earth pin in AC inlet and
exposed accessible parts. See Fig.1-1-10 and grounding
specifications.

SPECIFIC SERVICE INSTRUCTIONS
1.This camcorder has a built-in battery. The battery cannot be re-
placed by the user.
During disassembly/assembly, be careful not to get electrical
shock by touching and turning ON the power button, or not to
damage the circuits by short-circuiting.
2.A water damage/submersion indicator (white) is affixed in-
side.(Refer to the picture in the right.)
When the battery is damaged by the water or submerged, the in-
dicator turns to red.
3.When loading the battery to the main unit, be careful with the loading direction.
4.There is no adjustment needed after replacement of any parts.
5. Returning to the Factory Preset resets the following settings.
• File/ folder numbers
• Internal memory (image storage area) format
• Time setting
• Resolution setting
Procedure
(1) Download FN_Reset.dat from JS-NET.
Uploaded in "Special Tool" in "Service Support Software".
factory preset file for GC-FM1(31KB)
(2) Copy FN_Reset.dat to the SD card route.
(3) Insert the SD card into the slot on the main unit.
(4) Turn ON the power of the main unit.
(5) The power turns OFF automatically in about 1 second.
(6) Remove the SD card from the slot on the main unit.
NOTE
• If the remaining battery is less than half the capacity, a warning message appears and the reset cannot be performed.
• If a USB cable is connected for battery charging, the reset cannot be performed.
6. The firmware updated procedure is as follows.
(1) Download the relevant update file from JS-NET.
(2) Copy the update file to the SD card route.
(3) Insert the SD card into the slot on the main unit, then turn ON the power.
(4) An update screen appears.
(5) Selecting YES starts the update.
(6) When an update normal finish screen appears, turn OFF the power.
(7) Remove the SD card from the slot on the main unit.
7. The screw tightening torque is 0.108N*m (1.1kgf*cm) throughout the assembly procedure.
8. When the battery performance deteriorates, the following phenomena are observed.
• Abnormally long charging time
Normally, a completely empty battery finishes charging in about 3 hours. When the charging does not complete after about 6 hours
(twice the normal charging time), a battery trouble is considered.
If the charging does not complete after 12 hours, the charge LED blinks indicating an error.
• Abnormally short charging time
When a completely empty battery finishes charging in 10 to 20 minutes, battery abnormality is considered.
• Abnormally short discharge (usable) time
Although it varies according to environment, a fully charged new battery can record for about 70 minutes. If the battery becomes
empty (discharged) in several minutes, the battery capacity is considered to be extremely low.
9. Simple battery failure detection
When the voltage measures 2[V] or over between the (+) and (-) terminals, and the resistance measures 50[kΩ] to 150[kΩ] between
the (T) terminal and the GND, the battery is considered as a non defective battery.
(This does not indicate capacity decline. Use this measurement just as reference for detecting battery failure.)
