Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 ˚C
during repairing.
•Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
•Be careful not to apply force on the conductor when soldering
or unsoldering.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
•Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
•Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
•Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

Setting the Clock
The clock system varies depending on the model you
own.
12-hour system: “AM 12:00” = midnight
24-hour system: “0:00” = midnight
The time display of this clock is a 24-hour system.
1Press POWER to turn off the power.
2Press and hold down the jog lever for more
than 2 seconds until “the hour” starts
flashing.
3Slide or keep sliding the jog lever up or
down to adjust the hour and press the jog
lever.
If you keep sliding the jog lever up or down, the
number changes rapidly.
4Slide the jog lever up or down to adjust the
minutes and press the jog lever.
“:” starts flashing and the clock starts
operating.
To set the current time exactly to the second,
adjust the minute and then press the jog lever in
time with a time signal (such as a radio station).
To cancel the setting, press MODE.
Note
Once you start setting the clock, you must perform
each step within about 65 seconds, or the clock setting
mode will be cancelled.
