Safety Information and Place the AVR

for more than fifty years, the harman kardon mission has been to share a passion for music 

and entertainment, using leading-edge technology to achieve premium performance. 

Sidney harman and bernard kardon invented the receiver, a single component designed 

to simplify home entertainment without compromising performance. over the years, 

harman kardon products have become easier to use while offering more features and 

sounding better than ever.
the AVr 1700, AVr 170 and AVr 170/230c 5.1-channel digital audio/video receivers 

(AVrs) continue this tradition with some of the most advanced audio and video processing 

capabilities yet and a wealth of listening and viewing options.

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 of the grounding electrode.
NOTE TO CATV SYSTEM INSTALLER: this reminder is provided to call the cAtV (cable 

tV) system installer’s attention to article 820-40 of the nec, which provides guidelines 

for proper grounding and, in particular, specifies that the cable ground shall be connected 

to the grounding system of the building, as close to the point of cable entry as possible.

•  Place the AVR on a firm and level surface. Be certain that the surface and any mounting 

hardware can support the AVr’s weight.

•  Provide  proper  space  above  and  below  the  AVR  for  ventilation.  Recommended 

clearance distances are 30cm above the unit, 30cm behind the unit and 30cm on each 

side of the unit.

•  If you install the AVR in a cabinet or other enclosed area, provide cooling air within the 

cabinet. under some circumstances, a fan may be required.

•  Do not obstruct the ventilation slots on the top of the AVR or place objects directly 

over them.

•  Do not place the AVR directly on a carpeted surface.
•  Do not place the AVR in moist or humid locations, in extremely hot or cold locations, in 

areas near heaters or heat registers, or in direct sunlight.

Front-Panel Controls, continued

Power indicator/Power button: the AVr has four different power modes:
•  

Off (Power indicator not illuminated): when the rear-panel main power switch is 

in the off position or the power cord is unplugged the AVr is off and will not respond 

to any commands. plugging the power cord into a live Ac outlet and setting the main 

power switch in the on position will put the AVr into the eco Standby mode.

•  

Eco Standby (Power indicator glows solid amber): The Eco Standby mode minimizes 

energy consumption when you're not using the AVr. when the AVr is in eco Standby, 

it will not automatically turn on or play audio in response to an Airplay signal from a 

networked device. when the AVr is in eco Standby, pressing the power button turns it 

on. to put the AVr into eco Standby when it is on, press the power button for more than 

three seconds. 

•  

Standby (Power indicator glows solid amber): the Standby mode mutes the AVr 

and shuts off its front-panel display, but allows the AVr to automatically turn on and 

play audio in response to an Airplay signal from a networked device. See Listening 

to Media via AirPlay, on page 22, for more information. when the AVr is in Standby, 

pressing the power button turns it on. to put the AVr into Standby when it is on, press 

the power button for less than three seconds. 

•

Tuning Mode button (AVR 1700 only): this button toggles between manual (one 

frequency step at a time) and automatic (seeks frequencies with acceptable signal 

strength) tuning mode. It also toggles between stereo and mono modes when an fm 

station is tuned in.
RDS button (AVR 170 only): when listening to an fm radio station that broadcasts rdS 

information, this button activates the various rdS functions. note: rdS service may not 

be available in all areas.
Channel Level Control button: press this button to activate the channel-level adjustment 

feature. After pressing this button, use the up/down buttons to select the channel for 

adjustment and use the left/right buttons to adjust the channel’s level.
Digital Input button: press this button to change the audio input for the current source. 

use the left/right buttons to cycle through the available input connections, and press the 

Set button to assign the currently-displayed connection to the source.

name appears on the upper line, while the surround mode is displayed on the lower line. 

when the on-screen display menu system (oSd) is in use, the current menu settings 

appear.
Up/Down buttons/Tuning buttons: use these buttons to navigate the AVr’s menus. 

when the radio is the active source, use these buttons to tune stations according to the 

setting of the tuning mode button (see above).
Surround-Mode Category button: press this button to select a surround-sound 

category. each press changes the surround-mode category: Auto Select, Virtual, Stereo, 

movie, music and Video game. to change the specific surround-sound mode within the 

category, use the Surround mode Select buttons. See Audio Processing and Surround 

Sound, on page 23, for more information on surround modes.
Surround-Mode Select buttons: After you have selected the desired surround-mode 

category, press these buttons to select a specific mode within the category, such as to 

change from dolby

®

 pro logic

®

 II movie mode to logic 7

®

page 17.
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. HDD is not supported.
Volume knob: turn this knob to raise or lower the volume.
