18. Power lines – An outside antenna system should not
belocatedinthevicinityofoverheadpowerlinesorother
electric light or power circuits, or where it can fall into
such power lines or circuits. When installing an outside
antenna system, extreme care should be taken to keep
from touching such power lines or circuits as contact
with them might be fatal.
15. Damage requiring service – The appliance should
be serviced by qualified service personnel when:
A. The power-supply cord or the plug has been
damaged.
B. Objects have fallen, or liquid has been spilled
into the appliance.
C. The appliance has been exposed to rain or
water.
D. The appliance does not appear to operate
normally by following the instruction manual. Adjust
only those controls that are covered by the instruction
manualasanimproperadjustmentofothercontrolsmay
result in damage and will often require extensive work
by a qualified technician to restore the appliance to its
normal operation.
19. AC outlets – Do not connect other audio equipment
with a power consumption larger than that
specified to the AC outlet on the rear panel. Never
connect other electrical appliances, such as an
iron or toaster, to it to prevent fire or electric
shock.
E. The appliance has been dropped, or the
enclosure damaged.
F. The appliance exhibits a marked change in
performance.
20. Overloading – Do not overload wall outlets, extension
cords, or integral convenience receptacles as this can
result in a risk of fire or electric shock.
16. Servicing
–
The user should not attempt to
service the appliance beyond that described in the
instruction manual. All other servicing should be
referred to qualified service personnel.
21. Attachment – Do not use attachments not
recommended by the appliance manufacturer as they
may cause hazards.
17. Outdoor antenna grounding – If an outside
antenna is connected to the appliance, be sure the
antenna system is grounded so as to provide some
protection against voltage surges and built up
static charges. Article 810 of the National Electrical
Code ANSI/NFPA 70, 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 for the grounding electrode. See
Figure.
22. Replacement parts – When replacement parts are
required, be sure the service technician has used
replacement parts specified by the manufacturer or
have the same characteristics as the original parts.
Unauthorized substitutions may result in fire, electric
shock, or other hazards.
23. Safety check – Upon completion of any service or
repairs to this appliance, ask the service technician to

2 Connect theWireless Receiver (RFU-R6100) power cord to your power supply.
• The Wireless Receiver (RFU-R6100) power indicator lights up green.
3 Connect the AC adapter to theWirelessTransmitter (RFU-T6100) and power supply.
Use the enclosed AC adaptor
(AC-150015A) for this product.
4 Make sure you position both theWirelessTransmitter (RFU-T6100) andWireless Receiver (RFU-R6100) at least 2 meters
(6.6 ft.) apart.
• The control distance of the RF signal is about 30m (100 ft.) provided there is no obstacle.
5 Connect and carefully match the colors of the wires on the WirelessTransmitter (RFU-T6100) to the corresponding sur-
round speaker terminals on your Receiver.

7 On your Receiver, play an audio source and activate the surround sound mode option. Adjust the volume to reproduce
surround sound in the rear speakers.
8 Extend the antenna vertically on both the Wireless Receiver (RFU-R6100) and Wireless Transmitter (RFU-T6100) to im-
prove reception. Check the antennas are safely positioned without obstruction.
To ensure quality sound production and transmission
• Place both the Wireless Receiver (RFU-R6100) and Wireless Transmitter (RFU-T6100) off the ground (recommended minimum
height of 30cm (1 ft.)).
• Avoid placing the WirelessTransmitter (RFU-T6100) too close to your Receiver, AC adapter,TV or other electrical equipment as it
may cause electrical interference.
• In case of sound distortion, please select another channel for both the Wireless Receiver (RFU-R6100) and WirelessTransmitter
(RFU-T6100).The distortion could be the result of interference caused by other equipment using same frequency channel in your
house or neighbourhood.

Notes:
• After you switch off your Receiver, the Wireless Transmitter (RFU-T6100) automatically enters standby mode. On receiving an
incoming audio signal from your Receiver again, the WirelessTransmitter (RFU-T6100) automatically operate.
• When the Wireless Receiver (RFU-R6100) enters the standby mode, the power indicator lights up red.
• Do not position theWireless Receiver (RFU-R6100) andWirelessTransmitter (RFU-T6100) near metal (such as heat ducts). Metal
can absorb RF signals.
• When there is an obstruction around other equipments that send signal from theWirelessTransmitter (RFU-T6100), the reception
distance by the Wireless Receiver (RFU-R6100) will be short.
• The tests for range limits of theWireless Receiver (RFU-R6100) and theWirelessTransmitter (RFU-T6100) are conducted in open-
air distance test. Actual distance of the signal will be based on the construction of the building the unit is being used in as well as
other factors such as outside interference.
• As for the Wireless Transmitter (RFU-T6100) input of this Wireless Unit, it is optimal to use it with the receiver of Output Power
100 W.
Caution: Sound will be distorted if it is above 120 W of Output Power.
• It may be greatly audible by test tone reproduction with the standup of sound for a moment for a level setup of a Surround
Speaker.
• A noise may be heard if the WirelessTransmitter (RFU-T6100) is carried on your receiver. Please put on somewhere else.
Standby mode
While the standby indicator is lit, a small amount
of power is supplied to the system.This is called
standby mode.
