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 viscous (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.
Notes on chip component replacement
•Never reuse a disconnected chip component.
•Noticethat the minus side ofa tantalumcapacitor may be damaged
by heat.

TEST MODE
FACTORY PRESET MODE
*All preset contents are reset to the default setting.
*Procedure:
While depressing the PLII and the PRESETTUNING + buttons
simultaneously, press the power ?/1 button to turn on the main
power. The message “FACTORY” appears and the present
contents are reset to the default values.
RDS AUTOBETICAL MODE
*This mode is installed in the Europe models only. When this mode
is used, the receiver scans the broadcasts that can be received by
the tuner, and sets up the broadcasts. Be sure to start scanning
after connecting the antenna.
*Procedure :
1. Check that the antenna is connected.
2. While depressing the INPUT SELECTOR button, press the
?/1 button to turn on the main power.
3. The message “AUTO-BETICAL SELECT” appears and the
receiver starts scanning.
MICRO/NORMAL SPEAKER SELECTION MODE
*Either the micro speaker mode or normal speaker mode can be
selected.
*Procedure
While depressing the MUTING button, press the power ?/1
button to turn on the main power. Either the message “MICRO
SP.” or “NORM. SP.” appears. Select the desired mode.
SOUND FIELD CLEAR MODE
*The preset sound field is cleared when this mode is activated.
Use this mode before returning the product to clients upon
completion of repair.
*Procedure:
While depressing the SOUND FIELD button, press the power
?/1 button to turn on the main power. The message
“SF. CLR” appears and initialization is performed.
ALL CLEAR MODE
*The all preset value is cleared when this mode is activated.
*Procedure :
While depressing the PLII and the PRESET TUNING - buttons
simultaneously, press the power ?/1 button to turn on the main
power. The message “CLEARED” appears and clear all preset
value.
SOFTWARE VERSION DISPLAY MODE
*The software version is displayed.
*Procedure:
Whiledepressing the SOUNDFIELD and the PRESETTUNING
- buttons simultaneously, press the power ?/1 button to turn on
the main power. The model name, destination and the software
version are displayed.
KEY CHECK MODE
*Button check
*Procedure:
While depressing the MUTING and the INPUT SELECTOR
buttons simultaneously, press the power ?/1 button to turn on
the main power.
“REST 06” appears.
Every pressing of any button other than ?/1 counts down the
buttons. The buttons which are already counted once are not
counted again. When all buttons are pressed “REST 00” appears.
FLUORESCENT INDICATORTUBETEST MODE
*All fluorescent segments are tested. When this test is activated,
all segments turn on at the same time, then each segment turns on
one after another.
*Procedure:
While depressing the MUTING and the PRESET TUNING -
buttons simultaneously, press the power ?/1 button to turn on
the main power.
1. All segments turn on.
VIDEO , DVD , TV/SAT and TUNER LED turn on.
2. Press the INPUT SELECTOR button, confirm display
VIDEO , and TUNER LED turn on.
3. Press the INPUT SELECTOR button, confirm display
DVD and TV/SAT LED turn on.
4. Press the INPUT SELECTOR button, all segments and LEDs
turn off.
5. Every pressing of the INPUT SELECTOR button turns on
each segment and LED one after another in the same order.
TUNER CHECK MODE
*Tuner check
*Procedure :
While depressing the SOUND FIELD and the INPUT
SELECTOR buttons simultaneously, press the power ?/1
button to turn on the main power. “TUN CHK” appears and the
tuner checking is performed.
DSPTEST MODE
*DSP tests are performed.
*Procedure :
There are two different methods to enter the test mode.
(1) While depressing the INPUT SELECTOR and PRESET
TUNING- buttonssimultaneously, pressthe power ?/1 button
to turn on the main power.
(2) When the set is turned on, by using the remote controller, press
the ENTER button three times, then press the MAIN MENU
button one time and thenpress the MUTING button one time.
