Precautions
Installation place
This·unit·shall·be·installed·in·a·well-ventilated·and·effectively·
heat-released·place·because·this·unit·is·an·A-class·amplifier·
and·generates·considerable·heat.·
Especially,· installation· of· this· unit· where· direct· sunlight· is·
present,·where·the·temperature·rises·excessively·high· such·
as·close·to·a·heater,·or·where·it·is·humid·or·dusty·may·cause·
a·malfunction·even·if·heat·is·efficiently·released.·Therefore,·do·
not·install·this·unit·in·such·places.·
Ventilation holes
The·ventilation· holes·on· the·top· and·bottom· boards·of· this·
product·must·not·be·blocked·because·this·unit·is·an·A-class·
amplifier·and·generates·considerable·heat.·If·the·amplifier·is·
installed·on·a·rack·or·the·like,·secure·ample·space·for·cooling·
and·leave·the·door·open.·Do·not·pile·up·other·things·on·the·
amplifier·and·never·put·articles·on·it.·Failure· to·observe·this·
may·cause·a·malfunction.·
Note:
For·heat·dispersal,·do·not·install·this·equipment·in·a·confined·
space·such·as·a·book·case·or·similar·unit.
Precautions in connecting with other
components
When· connecting· this· unit· to· input· devices· such· as· a· CD·
player,·an·SACD·player,·a·tuner,·and·a·recorder,·be·sure·to·
turn·off·the·power·of·this·unit·and·all·other·connected·devices.·
Failure·to·observe·this·may·generate·a·strong·noise·resulting·
in·speaker·damage·or·cause·a·malfunction.·
The·pin-plug·to·be·inserted·in·each·input·terminal·of·this·unit·
shall· be· pushed· in· firmly.· If· the· grounding· terminal· is· inad-
equately·connected,·noises·including·hum·may·be·generated,·
resulting·in·an·adverse·S/N·ratio.·
Cautions in connecting speakers
When· making· speaker· system· connections,· exercise· extra·
care·not·to·short-circuit·between·!·and·@·of·the·speaker·ter-
minals·and·speaker·input·terminals·of·this·unit.·If·a·large·signal·
is·applied·to·the·amplifier·with·its·circuit·left·short-circuited,·a·
large·current·may·be·passed·through·the·output·circuit· and·
cause·a·malfunction.
The sound is not generated shortly after
the power supply is turned on.
This·amplifier·is·equipped·with·a·time·muting·circuit·in·order·to·
separate·the·output·circuit.··Therefore,·no·sound·is·generated·
shortly·after·the·power·supply·is·turned·on.·
If·the·volume·control·is·moved·to·a· high· sound·level·before·
the·time·muting·circuit·is·canceled,·a·large·sound·is·suddenly·
generated.·Please·be·advised·that·the·volume·control·shall·be·
set·to·a·low·level·at·first·and·adjusted·after·sound·comes·out·
of·the·speakers.·
Protection circuit
This·product·is·equipped·with·a·protection·circuit·that·is·ac-
tivated·upon·detection· of·overcurrent,·abnormally· high·tem-
perature,·and·DC·drift·to·protect·the·amplifier·and·speakers.·
When· the· protection· circuit· is· activated,· the· output· to· the·
speaker·terminal·is·shut·off·and·the·standby·indicator·blinks·to·
show·that·this·unit·is·in·the·muting·state.·If·the·protection·cir-
cuit·is·frequently·activated·even·when·disconnecting·the·pow-
er·plug·from·the· wall·outlet· and·turning·on·the·power·again·
after·a·lapse·of·a·certain·time,·please·consult·your·dealer.·
Batteries
Caution:
Batteries·used·for·remote·controller·shall·not·be·exposed·to·
excessive·heat·such·as·sunshine,·fire·or·the·like.
Repair and adjustment
When· repairs· or· adjustments· are· needed,· please· ask· the·
dealer·where·you·bought·the·unit.·
Cleaning
For·cleaning,·use·a·piece·of·soft·cloth·to·wipe·the·unit·such·as·
cleaning·cloth·available·on·the·market.·If·the·unit·has·become·
very·dirty,·remove·the·dirt·with·soft· cloth·absorbing· a·small·
amount·of·neutral·detergent,·and·then·wipe·the·unit·with·dry·
cloth.·Do·not·use·a·solvent·like·benzine·or·thinner·because·
