SAFETY PRECAUTIONS
The following items should be checked for continued protection of the customer and the service technician.
leakage current check
Beforereturningthesettothecustomer,besuretocarryouteither(1)aleakagecurrentcheckor(2)alinetochassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the
power cord is less than 460 kohms, the set is defective.
Be sure to test for leakage current with the AC plug in both polarities, in addition, when the set's power is in each state
(on,offandstandbymode),ifapplicable.
CAUTION Please heed the following cautions and instructions during servicing and
inspection.
◎Heed the cautions!
Cautions which are delicate in particular for servicing
are labeled on the cabinets, the parts and the chassis,
etc. Be sure to heed these cautions and the cautions
described in the handling instructions.
◎Cautions concerning electric shock!
(1) AnACvoltageisimpressedonthisset,soifyou
touch internal metal parts when the set is energized,
youmaygetanelectricshock.Avoidgettingan
electricshock,byusinganisolatingtransformer
and wearing gloves when servicing while the set is
energized,orbyunpluggingthepowercordwhen
replacing parts, for example.
(2) Therearehighvoltagepartsinside.Handlewith
extra care when the set is energized.
◎Caution concerning disassembly and
assembly!
Through great care is taken when parts were
manufacturedfromsheetmetal,theremaybeburrson
theedgesofparts.Theburrscouldcauseinjuryifngers
are moved across them in some rare cases. Wear gloves
toprotectyourhands.
◎Use only designated parts!
Theset'spartshavespecicsafetyproperties(re
resistance,voltageresistance,etc.).Besuretouseparts
which have the same properties for replacement. The
burrs have the same properties. In particular, for the
importantsafetypartsthatareindicatedbythezmark
on schematic diagrams and parts lists, be sure to use
the designated parts.
◎Be sure to mount parts and arrange the wires
as they were originally placed!
Forsafetyseasons,somepartsusetapes,tubesorother
insulatingmaterials,andsomepartsaremountedaway
from the surface of printed circuit boards. Care is also
takenwiththepositionsofthewiresbyarrangingthem
andusingclampstokeepthemawayfromheatingand
highvoltageparts,sobesuretoseteverythingbackas
itwasoriginallyplaced.
◎Make a safety check after servicing!
Check that all screws, parts and wires removed or
disconnected when servicing have been put back in their
original positions, check that no serviced parts have
deteriorate the area around. Then make an insulation
check on the external metal connectors and between
the blades of the power plug, and otherwise check that
safetyisensured.
(Insulationcheckprocedure)
Unplug the power cord from the power outlet, disconnect
the antenna, plugs, etc., and on the power. Using a 500V
insulation resistance tester, check that the insulation
resistancevaluebetweentheinplugandtheexternally
exposedmetalparts(antennaterminal,headphones
terminal,inputterminal,etc.)is1MΩorgreater.Ifitis
less, the set must be inspected and repaired.
Manyoftheelectricandthestructuralpartsusedinthe
sethavespecialsafetyproperties.Inmostcasesthese
propertiesaredifculttodistinguishbysight,andtheuse
ofreplacementpartswithhigherratings(ratedpower
andwithstandvoltage)doesnotnecessarilyguarantee
thatsafetyperformancewillbepreserved.Partswith
safetypropertiesareindicatedasshownbelowonthe
wiring diagrams and the parts list in this service manual.
Be sure to replace them with the parts which have the
designated part number.
(1) Schematicdiagrams.......Indicatedbythez mark.
(2) Partslists.......Indicatedbythezmark.
The use of parts other than the
designated parts could cause electric
shocks,resorotherdangerous
situations.
CAUTION Concerning important
safety parts

PRECAUTIONS DURING SERVICE
Initializing This Unit
Initialize this unit if you have replaced the microcomputer, one of the parts around the microcomputer, or the digital PCB.
1. Press the power button to turn off the power.
2. Hold down buttons "TUNER PRESET -" and "TUNER PRESET +" at the same time and press the power button to turn
on the power.
3. Release the buttons after conrming that the display ashes in intervals of approximately 1 second.
＊The unit is initialized.
NOTE：• If the status in step 3 does not occur, start again from step 1.
• Initializing the device restores settings congured by the user to the factory settings. Take note of your settings beforehand
and recongure them after initialization.
Service Jigs
The following jigs (extension cable kit) are used when repairing the PCBs.
Order the jigs from your dealer if necessary.
