Place the Stereo Receiver

• Place the Stereo receiver on a firm and level surface. Be certain that the surface and any mounting hardware can support the
Stereo receiver’s weight.

• Provide proper space above, below, behind and to the sides of the Stereo receiver for ventilation. Maintain a clearance of at least 12"
(30cm) on each side of, above and behind the unit.

• If you install the Stereo receiver in a cabinet or other enclosed area, provide cooling air within the cabinet. Under some circumstances,
a fan may be required.

• Do not obstruct the ventilation slots on the top of the Stereo receiver or place objects directly over them.

• Do not place the Stereo receiver directly on a carpeted surface.

• Do not place the Stereo receiver in moist or humid locations, in extremely hot or cold locations, in areas near heaters or heat registers,
or in direct sunlight.

How to use the Stereo receiver speaker terminals:

1. Unscrew Cap 2. Insert Bare Wire 3. Tighten Cap

Wire with black
stripe is ‘_’ terminal

Always connect the colored (+) terminal on the Stereo
receiver to the (+) terminal on the speaker (usually
red), and the black (–) terminal on the Stereo receiver
to the (–) terminal on the speaker (usually black).

IMPORTANT: Make sure the ( + ) and ( – ) bare wires do
not touch each other or the other terminal. Touching
wires can cause a short circuit that can damage your
Stereo receiver. Connect the speakers as shown in the
illustration.

A source device is a component where an audio playback signal originates
from, like a CD player, DVD player, Cable, Satellite or HDTV boxes, Tuner,
etc. Your Stereo receiver has several different types of input connectors to
accommodate to those different components: Phono input, analog audio
inputs, optical digital audio inputs (HK3770 only) and coaxial digital audio
input (HK3770 only). The Analog audio input are not labeled for specific
types of source devices but they are labeled numerically from A1 to A5
(AUX inputs)

Your Stereo receiver's various auxiliary (AUX) analog inputs can be selected
by the remote control using the AUX button. Simply press the AUX button
to cycle between the various inputs:

AUX 1 --> AUX 2 --> AUX3 ... AUX5 --> AUX1

KH 3770 only: Your Stereo receiver's digital audio inputs label on the
back panel of the stereo receiver COAXIAL, OPTICAL 1 and OPTICAL 2 can
be selected by the remote control using the DIGITAL button. Simply press
the Digital button to cycle between the various inputs:

COAXIAL --> OPTICAL 1 --> OPTICAL 2 --> COAXIAL

Note: the other sources of the Stereo receiver like Phono input, FM/AM
tuner, Internet radio Vtuner, USB audio play back, Bluetooth and Network
DLNA have direct access buttons on the remote control.

Federal Communication Commis­sion Interference Statement

This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to pro­vide reasonable protection against harmful interference
in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not

occur in a particular installation. If this equipment does
cause harmful interference to radio or television recep­tion, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and

receiver.

• Connect the equipment into an outlet on a circuit differ­ent from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV techni­cian for help.

Caution: Changes or modifications not expressly ap­proved by HARMAN could void the user’s authority to op­erate the equipment.

FCC AND IC INFORMATION FOR USERS

This device complies with Part 15 of the FCC rules and
Industry Canada license-exempt RSS 210. Operation is
subject to the following two conditions: (1) This device
may not cause harmful interference; and (2) this device
must accept any interference received, including interfer­ence that may cause undesired operation.

FCC/IC Radiation Exposure Statement

For Products with Radio Re­ceivers That Can Use an Ex­ternal Antenna (USA ONLY):

CATV (Cable TV) or Antenna Grounding

If an outside antenna or cable system is connected to
this product, be certain that it is grounded so as to pro­vide some protection against voltage surges and static
charges. Section 810 of the National Electrical Code
(NEC), ANSI/NFPA No. 70-1984, provides information with
respect to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna dis­charge unit, size of grounding conductors, location of an­tenna discharge unit, connection to grounding electrodes
and requirements of the grounding electrode.

Note to CATV System Installer:

This reminder is provided to call the CATV (cable TV)
system installer’s attention to article 820-40 of the NEC,
which provides guidelines for proper grounding and, in
particular, specifies that the cable ground shall be con­nected to the grounding system of the building, as close
to the point of cable entry as possible.
