Precautions
THE FOLLOWING APPLIES ONLY IN THE 
U.S.A. AND CANADA
This device complies with Part 15 of FCC Rules and RSS-
Gen of IC Rules.
Operation is subject to the following two conditions: 
(1) This device may not cause interference, and  (2) this 
device must accept any interference, including 
interference that may cause undesired operation of this 
device.
This transmitter must not be co-located or operated in 
conjunction with any other antenna or transmitter.
This product is restricted to indoor use due to its operation 
in the 5.150 GHz to 5.250 GHz and 5.725 GHz to 
5.850 GHz frequency range.
FCC and IC require this product to be used indoors for the 
frequency range 5.150 GHz to 5.250 GHz and 5.725 GHz 
to 5.850 GHz to reduce the potential for harmful 
interference to co-channel Mobile Satellite systems. High 
power radars are allocated as primary users of the 
5.25 GHz to 5.35 GHz and 5.65 GHz to 5.85 GHz bands. 
These radar stations can cause interference with and/or 
damage this product.
This equipment complies with FCC/IC radiation exposure 
limits set forth for an uncontrolled environment and meets 
the FCC radio frequency (RF) Exposure Guidelines in 
Supplement C to OET65 and RSS-102 of the IC radio 
frequency (RF) Exposure rules. This equipment has very 
low levels of RF energy that is deemed to comply without 
maximum permissive exposure evaluation (MPE). But it is 
desirable that it should be installed and operated keeping 
the radiator at least 20 cm (7 7/
8q) or more away from 
person’s body (excluding extremities: hands, wrists, feet 
and ankles).
The lightning flash with arrowhead 
symbol, within an equilateral triangle, 
is intended to alert the user to the 
presence of uninsulated “dangerous 
voltage” within the product’s 
enclosure that may be of sufficient 
magnitude to constitute a risk of 
electric shock to persons.
The exclamation point within an 
equilateral triangle is intended to alert 
the user to the presence of important 
operating and maintenance 
(servicing) instructions in the literature 
accompanying the appliance.
CAUTION: TO REDUCE THE RISK OF ELECTRIC 
SHOCK, DO NOT REMOVE SCREWS.
NO USER-SERVICEABLE PARTS 
INSIDE.
REFER SERVICING TO QUALIFIED 
SERVICE PERSONNEL.
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
THE FOLLOWING APPLIES ONLY IN THE 
U.S.A.
FCC Note:
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.
Any unauthorized changes or modifications to this 
equipment would void the user’s authority to operate this 
device.
This device complies with Part 15 of the FCC Rules.
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.

≥Use a screwdriver (i) for assembling the speakers.
≥Do not hold the speakers in one hand to avoid injury, you may drop the speakers when carrying them.
When carrying the active subwoofer
To avoid interference, maintain the following distances between the main unit/active subwoofer 
and other electronic devices that use the same radio frequency (2.4 GHz and 5 GHz band).
≥Place the active subwoofer within a few meters of the main unit and in a horizontal position with the top panel faced upward.
≥Do not use the main unit or active subwoofer in a metal cabinet.
≥Placing the active subwoofer and the speakers too close to the walls and corners can result in excessive bass. Cover walls 
and windows with thick curtains.
≥If irregular coloring occurs on your TV, turn the TV off for about 30 minutes. If it persists, move the speakers further away from 
the TV.
≥Keep magnetized items away. Magnetized cards, watches, etc., can be damaged if placed too close to the active subwoofer 
and the speakers.
Caution
≥This system is to be used only as indicated in these instructions. Failure to do so may lead to damage to the 
amplifier and/or the speakers, and may result in the risk of fire. Consult a qualified service person if damage 
has occurred or if you experience a sudden change in performance.
≥Do not attempt to attach these speakers to a wall using methods other than those described in this manual.
Speaker system
∫When attaching the speakers to a wall
The wall or pillar on which the speakers are to be attached should be capable of supporting 33 kg (72.8 lbs) per screw. 
Consultation with a qualified building contractor is recommended when attaching the speakers to a wall. Improper attachment 
may result in damage to the wall and speakers, and personal injury.
∫When placing the speakers in front of the TV
The speakers may block or interfere with the TV’s various sensors (C.A.T.S. (Contrast Automatic Tracking System) sensor, 
remote control sensor, etc.) and the 3D Eyewear transmitters on a 3D compatible TV.
≥If the stands are being used
Move the speakers further away from the TV. If the TV still does not function properly, try removing the stands.
≥If the stands are not used
Move the speakers further away from the TV. If the TV still does not function properly, try placing them beside the TV (>8).
Active subwoofer
Do not hold the active subwoofer from this 
opening.
The parts inside (speaker unit) may be damaged.
Always hold the bottom of the active subwoofer when 
moving it.

Getting started
RQT9660 17
Connect the speaker cables. 
≥Insert the wire fully, taking care not to insert beyond the wire insulation.
≥Place the speaker that is connected with the speaker cable with a red connector on the observers’ right, and connect with 
the speaker cable with a white connector on the observers’ left.
To prevent the speakers from falling, it is recommended, as an additional 
protection measure, to attach the speakers to the wall or table with a fall 
prevention cord (hereafter “cord”).
≥Consultation with a qualified housing contractor concerning the appropriate procedure when attaching to a concrete wall or a 
surface that may not have strong enough support is recommended (>11, 13). Improper attachment may result in damage to 
the wall and speakers, and personal injury.
≥Use a cord of less than ‰2.0 mm (5/64q), which is capable of supporting over 10 kg (22.05 lbs).
≥Keep the screws out of reach of children to prevent swallowing.
≥Make sure that the slack of the cord is minimal.
