Precautions
On safety
Should any solid object or liquid fall into the cabinet, unplug the receiver
and have it checked by qualified personnel before operating it any
further.
On power sources
Before operating the receiver, check that the operating voltage is

identical with your local power supply.
The operating voltage is indicated on the nameplate on the back of the
receiver.
If you are not going to use the receiver for a long time, be sure to

disconnect the receiver from the wall outlet. To disconnect the AC power
cord (mains lead), grasp the plug itself; never pull the cord.
One blade of the plug is wider than the other for the purpose of safety

and will fit into the wall outlet only one way. If you are unable to insert
the plug fully into the outlet, contact your dealer.
AC power cord (mains lead) must be changed only at a qualified service

shop.
To reduce the risk of electric shock, the speaker cable should be

connected to the apparatus and the speakers in accordance with the
following instructions.
1) Disconnect the AC power cord from the MAINS.
2) Strip 10 to 15 mm (13/32 to 19/32 in) of the wire insulation of the
speaker cable.
3) Connect the speaker cable to the apparatus and the speakers
carefully so as not to touch the core of speaker cable by hand. Also
disconnect the AC power cord from the MAINS before disconnecting
the speaker cable from the apparatus and the speakers.
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.
* The top of the cabinet may become too hot to touch.

On updating
This receiver allows you to update the software automatically when
connected to the Internet via a wired or wireless network.
You can add new features and use the receiver with more convenience

If you do not want to update automatically, set [Auto Update] to [Off].
However, the receiver may update the software automatically for reasons
such as safety, even if this function is disabled. You can also update the

On Internet connection
When connecting the receiver to the Internet, use the router (ADSL
modem or optical line termination device with the router function
supplied with the Internet provider, or Wi-Fi access point). If you connect
to the Internet without using the router, a security problem may occur. If
you are not sure that the wall outlet for the network line has the router
function, ask your manager of the apartment house or Internet provider.
