Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called
Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and
semiconductor "chip" components.
The following techniques should be used to help reduce the incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on
your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,
which should be removed for potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to
prevent electrostatic charge build-up or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges
sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement
ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)
7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the
chassis or circuit assembly into which the device will be installed.
CAUTION :
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together
or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.
Each precaution in this manual should be followed during servicing.
Components identified with the IEC symbol in the parts list are special significance to safety. When replacing a component identified with
, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably
insulated from the supply circuit before retuming the product to the customer.
-4-
Before returning the unit to the user, perform the following safety checks :
1. Inspect all lead dress to make certain that
leads are not pinched or that hardware is not
lodged between the chassis and other metal
parts in the unit.
2. Be sure that any protective devices such as
nonmetallic control knobs, insulating fish-
papers, cabinet backs, adjustment and
compartment covers or shields, isolation
resistor-capacity networks, mechanical
insulators, etc. Which were removed for the
servicing are properly re-installed.
3. Be sure that no shock hazard exists ; check for leakage
current usingSimpson Model 229 Leakage Tester, standard
equipment item No. 21641, RCA Model WT540A or use
alternate method as follows : Plug the power cord directly
Into a 120 volt AC receptacle (do not use an Isolation
Transformer for this test). Using two clip leads, connect a
1500 ohms,10watt Resistor paralleledbya 0.15uF capacitor, in serieswith all exposed metalcabinet parts andaknown earth ground,such
as a water pipe or conduit. Use a VTVM or VOM with 1000 ohms per volt, or higher sensitivity to measure the AC voltage drop across the
resistor. (See diagram) Move the resistor connection to each exposed metal part having a return path to the chassis (antenna, metal,
cabinet, screwheads,knobsandcontrolshafts,escutcheon,etc.)and measure the AC voltage drop acrosstheresistor. (This test should be
performed withthe 0.35 voltRMS or moreis excessive andindicates a potentialshock hazard whichmust be correctedbefore returning the
unit to the owner.

to show that a standard PCM(SP/DIF) digital
audio signal is being decoded by the digital-toanalog converter.
Surround Mode Indicators :
indicators illuminate when one of the DSP
generated analog surround modes is in use
with an analog input source.
Night Indicator :
the AVR-35 is in the Night mode, which
prevents the AVR-35 from loud playback when
digital sources are in use.
Preset Number :
indicates the station preset number that is
currently in use, or of that is being entered.
Preset Indicator :
when one of the stations entered into the
preset memory is tuned. The number that
appears below the indicator is the preset
station's memory.
Memory :
entering presets and other information into the
tuner's memory.

Stereo Indicator :
when an FM station is being tuned in stereo.
Mono Indicator :
when the tuner has been placed in the
monaural mode by pressing the
18
button . Set the tuner for mono listening to
cut noise and improve the quality of distant
stereo signals.
Tuned Indicator :
when a station is being received with sufficient
signal strength to allow for acceptable listening
quality.
Main Information Display :
shows messages relating to the status, input
source, surround mode, tuner, volume level or
other aspects of unit's operation.
Sleep Indicator :
illuminated when the Sleep function is in use.

2. VFD segment illumination & text
This service procedure will illuminate all segments by the following steps
(1) Press the Power ON buttn(Push Knob) while you are holding the TEST TONE (dts) button.
(2) Then "TEST MODE" character will be shown on VFD Display.
(3) This set do not have Auto VFD segement check function. So For your checking the VFD
states according to each function, Please press any function button which you want to test.
(4) for example : Tape monitor & CD
1) Press the POWER ON button(push knob) while you are holding the TEST TONE (dts) button.
2) Then "TEST MODE" character will be shown on VFD Display.
3) Press the t.MON button on Front, then you are able to see " TAPE MONITOR" Character on VFD Display.
4) Press the CD button on FRont, then you are able to see "CD" Character on VFD Display.
