1. IMPORTANT SERVICE NOTES
BEFORE RETURNING THE VIDEO CAMERA
RECORDER
Before returning the video camera recorder to the user,
perform the following safety checks.
1. Inspect all lead dress to make certain that leads are
not pinched or that hardware is not lodged between
the chassis and other metal parts in the video camera
recorder.
2. Inspect all protective devices such as non-metallic
control knobs, insulating materials, cabinet backs,
adjustment and compartment covers or shields, isola-
tion resistor/capacitor networks, mechanical insula-
tors etc.
3. To be sure that no shock hazard exists, check for
leakage current in the following manner.
· Plug the AC line cord directly into a 120 volt AC outlet
(Do not use an isolation transformer for this test).
· Using two clip leads, connect a l.5k ohm, 10 watt resistor
paralleled by a 0.15µF capacitor in series with all
exposed metal cabinet parts and a known ground,
such as a water pipe or conduit.
· Use a VTVM or VOM with 1000 ohm per volt, or higher
sensitivity or measure the AC voltage drop across the
resistor (See Diagram).
· Move the resistor connection to all exposed metal
parts having a return path to the chassis (antenna
connections, metal cabinet, screw heads, knobs and
control shafts, etc.) and measure the AC voltage drop
across the resistor. Reverse the AC plug (a non
polarized adaptor plug must be used but only for the
purpose of completing these checks) on the set and
repeat the AC voltage measurements for each ex-
posed metallic part. Any reading of 0.45V rms (this
corresponds to 0.3mA rms AC.) or more is excessive
and indicates a potential shock hazard which must be
corrected before returning the video camera recorder
to the user.

■ PRECAUTIONS FOR USING LEAD-FREE SOLDER
1) Employing lead-free solder
"Main PWB", "Camera head PWB", "Audio I/O PWB", "Card PWB", "Inverter PWB", "Operation PWB", "DC Jack
PWB", "CCD PWB" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached
on the PWBs and service manuals. The alphabetical character following LF shows the type of lead-free solder.
Example:
Indicates lead-free solder of tin, silver and copper
2) Using lead-free solder
When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional
lead wire solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40°C, we recommend you
to use a dedicated soldering bit. If you are not familiar with how to obtain lead-free solder or soldering bit, contact
our service station or service ranch in your area.
3) Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is 220°C which is higher than the conventional lead solder by
40°C, and as it has poor solderability, you may be apt to keep the soldering bit in contact with the PWB for extended
period of time. However, since the land may be peeled off or the maximum heat-resistance temperature of parts may
be exceeded, remove the bit from the PWB as soon as you confirm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on
and off the power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after
every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.

4-2. REPLACEMENT OF CCD SENSOR
4-2-1. BEFORE REPLACEMENT
1) The CCD image sensor is more sensitive to electrostatic breakage than C-MOS LSI.Therefore sufficient means
to prevent electrostatic damage must be taken when it is replaced.
• Ground the soldering iron.
• Ground also the human body, using the wrist strap(through an 1 M ohm resistor).
• Until the CCD sensor is mounted on the PWB, fit it to the conductive sponge, and short-circuit the foot lead.
2) Take utmost care so that the surface glass of CCD sensor and optical filter are not contaminated and damaged.
If any contamination is found, for example fingerprint, wipe it off with silicon paper or clean chamois skin.
3) When replacing the CCD sensor, use the static electricity prevention grounded soldering-iron, and perform
quickly soldering.

4-2-2. REMOVAL OF CCD
1) Unsolder the CCD sensor leads from the MAIN PWB.
2) Take out the MAIN PWB.
3) Remove the three screws (LX-HZ0013TAFF), and remove the sensor holder and CCD sensor.
4-2-3. MOUNTING OF CCD
1) Place the lens unit upright (since the CCD sensor mount ID faces upward, care must be taken so as not to
damage the front lens of unit), put the crystal filter first and then the dust protection rubber into the CCD holder
of lens unit.
Set the crystal unit with its thin side toward the lens unit.
2) Place the CCD sensor so that the its No. 1 pin is at the right lower (Positioning hole to be at right), and put the
CCD sensor into the CCD holder. For smooth and tight fitting, press the right lower part of back of CCD sensor,
and then press the left upper part.
Note: Pay attention to the direction of CCD sensor.
3) Place the sensor holder so that its two round markings be visible, and fix the sensor holder with the theree screws
(LX-HZ0013TAFF).
4) Mount the MAIN PWB so that the CCD sensor leads go thorough the PWB holes.
5) Solder the CCD sensor lead to the sensor PWB.
Note: Take care not to apply excessive heat.
