HK3490 harman/kardon
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 : Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
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
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.

HK3490 harman/kardon
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 using Simpson 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 paralleled by a 0.15uF capacitor, in series with all exposed metal cabinet parts and a known 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, screw heads, knobs and control shafts, escutcheon, etc.) and measure the AC voltage drop across the resistor. (This test should be
performed with the 0.35 volt RMS or more is excessive and indicates a potential shock hazard which must be corrected before returning the
unit to the owner.

your turntable is equipped with its own onboard phono preamp, you
may connect it to any of the HK 3490's other audio inputs.
Main Power Switch: This mechanical switch turns the power supply
on or off. It is usually left turned on (push the rocker in at the top), and
cannot be turned on using the remote control. Turn this switch off when
connecting or disconnecting source devices or loudspeakers to prevent
any possibility of damage to components resulting from an unexpected

There are different types of audio and video connections used to
connect the receiver to the speakers and video display, and to connect
the source devices to the receiver. To make it easier to keep them all
straight, the Consumer Electronics Association has established a CEA®

Analog connections require two cables, one for the left channel (white)
and one for the right channel (red). These two cables are often attached
to each other for most of their length. See Figure 6. Most sources that
have digital audio jacks also have analog audio jacks, although some
