On heat buildup
Although the receiver heats up during 
operation, this is not a malfunction. If you 
continuously use this receiver at a large 
volume, the cabinet temperature of the top, 
side and bottom rises considerably. To 
avoid burning yourself, do not touch the 
cabinet.
On placement
• Place the receiver in a location with 
adequate ventilation to prevent heat 
buildup and prolong the life of the 
receiver.
• Do not place the receiver near heat 
sources, or in a place subject to direct 
sunlight, excessive dust, or mechanical 
shock.
• Do not place anything on top of the 
cabinet that might block the ventilation 
holes and cause malfunctions.
• Do not place the receiver near equipment 
such as a TV, VCR, or tape deck. (If the 
receiver is being used in combination 
with a TV, VCR, or tape deck, and is 
placed too close to that equipment, noise 
may result, and picture quality may 
suffer. This is especially likely when 
using an indoor antenna (aerial). 
Therefore, we recommend using an 
outdoor antenna (aerial).)
• Use caution when placing the receiver on 
surfaces that have been specially treated 
(with wax, oil, polish, etc.) as staining or 
discoloration of the surface may result.
On operation
Before connecting other equipment, be sure 
to turn off and unplug the receiver.
On cleaning
Clean the cabinet, panel, and controls with 
a soft cloth slightly moistened with a mild 
detergent solution. Do not use any type of 
abrasive pad, scouring powder, or solvent, 
such as alcohol or benzine.
On Bluetooth 
communication
•Bluetooth devices should be used within 
approximately 10 meters (33 feet) 
(unobstructed distance) of each other. 
The effective communication range may 
become shorter under the following 
conditions.
– When a person, metal object, wall or 
other obstruction is between the 
devices with a Bluetooth connection
– Locations where a wireless LAN is 
installed
– Around microwave ovens that are in 
use
– Locations where other electromagnetic 
waves occur
•Bluetooth devices and wireless LAN 
(IEEE 802.11b/g) use the same frequency 
band (2.4 GHz). When using your 
Bluetooth device near a device with 
wireless LAN capability, electromagnetic 
interference may occur. This could result 
in lower data transfer rates, noise, or 
inability to connect. If this happens, try 
the following remedies:
– Use this receiver at least 10 meters 
(33 feet) away from the wireless LAN 
device.
– Turn off the power to the wireless LAN 
equipment when using your Bluetooth 
device within 10 meters (33 feet).
– Install this receiver and Bluetooth 
device as closer to each other as 
possible.
• The radio waves broadcast by this 
receiver may interfere with the operation 
of some medical devices. Since this 
interference may result in malfunction, 
always turn off the power on this receiver 
and Bluetooth device in the following 
locations:
– In hospitals, on trains, in airplanes, at 
gas stations, and any place where 
flammable gasses may be present
– Near automatic doors or fire alarms
