AVR146 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.

SAFETY PRECAUTIONS
The following check should be performed for the continued
protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground (water
pipe, conduit, etc.) by connecting a leakage current tester
between the earth ground and all exposed metal parts of the
appliance (input/output terminals, screwheads, metal
overlays, control shaft, etc.). Plug the AC line cord of the
appliance directly into a 120V AC 60Hz outlet and turn the
AC power switch on. Any current measured must not exceed
o.5mA.

Composite video is the basic connection most commonly available.
The jack is usually color-coded yellow, and looks like an analog audio
jack, although it is important never to confuse the two. Do not plug a
composite video cable into an analog or coaxial digital audio jack, or
vice versa. Both the chrominance (color) and luminance (intensity)
components of the video signal are transmitted using a single cable.

S-video, or "separate" video, transmits the chrominance and luminance
components using separate wires contained within a single cable. The
plug on an S-video cable contains four metal pins, plus a plastic guide
pin. Be careful to line up the plug correctly when you insert it into the
jack on the receiver, source or video display. See Figure 11.

INSTALLATION
You are now ready to connect your various components to your receiver. Step Three Connect the Antennas
Before beginning, make sure that all components, including the AVR 146,
are turned completely off and their power cords are unplugged. Don't Connect the FM and AM antennas to their terminals. See Figure 18.
plug any of the power cords back in until you have finished
making all of your connections.
Remember that your receiver generates heat while it is on. Select a
location that leaves several inches of space on all sides of the receiver.

It is preferable to avoid completely enclosing the receiver inside an
unventilated cabinet. It is also preferable to place components on
separate shelves rather than stacking them directly on top of the
receiver. Some surface finishes are delicate. Try to select a location
with a sturdy surface finish.
