Power indicator/Power button: the AVr has three different power modes:
off (power indicator glows solid amber): the off mode minimizes energy consumption •
when you’re not using the AVr. when the AVr is off, it will not automatically turn on
or play audio in response to an Airplay stream from a networked device (AVr 1710/
AVr 171 only). when the AVr is off, pressing the power button turns it on. to turn
the AVr off when it is on, press the power button for more than three seconds. the
Front-panel display will indicate “Your device is switched off” for two seconds, then
will switch off.
note: You can use the System Setup menu to set the AVr to automatically enter
the off mode after it has been in the Sleep mode for a certain period of time. See
System Settings, on page 34.
Sleep
• (power indicator glows solid amber and front-panel display indicates “device
sleep”): the Sleep mode powers-down some of the AVr’s circuitry, but allows the
AVr to automatically turn on and play audio in response to an Airplay or dlnA
dMr stream from a networked device (AVr 1710/AVr 171 only). when the AVr is
in Sleep, pressing the power button turns it on. to put the AVr into Sleep when it is
on, press the power button for less than three seconds. the front-panel display will
indicate “device sleep” while the AVr is in the Sleep mode.
note: the AVr will automatically enter the Sleep mode after 30 minutes of no audio
signal or user control input , unless uSb, ipod, home network, vtuner, Airplay, or
dlnA dMr is active. In these cases, the AVr will automatically enter the Sleep mode
after the number of hours set in the Auto power off system setting. See System
Settings, on page 34.
On • (power indicator glows solid white): when the AVr is on it is fully operational.
Headphone jack/EzSet/EQ Mic input: connect a 1/4” stereo headphone plug to this
jack for private listening. this jack is also used to connect the supplied microphone for
the ezSet/eq setup procedure described in Configure the AVR For Your Speakers, on
page 22.
Tuning Mode button (AVR 1710/AVR 1610 only): press this button to toggle the radio
between the manual (one frequency step at a time) and automatic (seeks frequencies
with acceptable signal strength) FM tuning mode. the button also toggles the radio
between stereo and mono modes when an FM station is tuned in.
RDS button (AVR 171/AVR 161 only): when listening to an FM radio station that
broadcasts rdS information, this button activates the various rdS functions.
USB port:
the uSb port can be used to play audio files from an Apple ioS ® device
connected to the port, and can also be used to play Mp3 and wMA audio files from a uSb
device inserted into the port. Insert the connector or device into the uSb port oriented so
it fits all the way into the port. You may insert or remove the connector or device at any
time – there is no installation or ejection procedure.
You can also use the uSb port to perform firmware upgrades. If an upgrade for the AVr’s
operating system is released in the future, you will be able to download it to the AVr
using this port. complete instructions will be provided at that time.
IMPORTANT: Do not connect a PC or other USB host/controller to this port, or you
may damage both the AVR and the other device.
