Precautions for using lead-free solder
1 Employing lead-free solder
"Operation (R) PWB, Operation (L) PWB, Power PWB and Tuner 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:
2 Using lead-free wire 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 wire solder or soldening 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 about 220
°
C which is higher than the conventional lead solder
by 40
°
C, and as it has poor solder wettabillty, 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 excoeded, remove the bit from the PWB as soon as you conurm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to tum 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.
Becareful when replacing parts with polarity indication on the PWB silk.

Comprehensive editing functions
(Only titles recorded on the hard disc or in VR mode on
DVD-RW can be edited.)
 1
Play list edit
This lets you gather only the needed parts (i.e. a "Play List")
from a recorded original video (title).
You can rearrange scenes and combine them with other
scenes, or rearrange titles. This is convenient when you want
to dub and save only the necessary scenes and titles.
 2
Chapter edit
This lets you divide a title into chapter units during recording/
playback or using the edit screen. After dividing, a list of
recordings (thumbnails) can be displayed in chapter units,
so you can copy, erase or dub to the play list in chapter units.
 3
Erase Scene
This lets you erase unnecessary scenes. This is convenient
when you want to cut out the commercials in a recorded
program before dubbing.
 4
Batch erasing of titles/chapters
Titles and chapters which become unnecessary after editing
can be batch erased by selecting them from the list of
recordings (thumbnails).
 5
Edit undo function
*2
If you mistakenly erase data during editing, this function lets
you restore it to its immediately preceding state, just like
"Undo" on a PC, so you can edit worry-free.
     
*2
Edit undo can only be used once. It only works when "UNDO"
is assigned to a coloured button (green) displayed on the
screen.
