Power Indicator: This LED has three possible modes: 
Main Power Off
 
: When the AVR is unplugged or the Main Power 
Switch is off, this LED is off. 
Standby
 
: Amber indicates that the AVR is ready to be turned on.
On
 
: When the AVR is turned on, this LED turns white.
NOTE: If the PROTECT message ever appears, turn off the AVR and unplug 
it. Check all speaker wires for a possible short. If none is found, bring the 
unit to an authorized Harman Kardon service center for inspection and 
repair before using it again.
Standby/On Switch: This electrical switch turns the receiver on, or places 
it in Standby mode for quick turn-on.
RDS: Activates RDS functions for FM Radio
Channel Level Control: Press this button to adjust the output level for 
any amplifier channel. It may be necessary to raise or lower the level of a 
specific channel to compensate for the placement of the relevant speaker in 
the room in relation to the listening position; e.g., the center channel speaker 
is further away from the listening position than the front left and right 
speakers, so that the dialogue is too soft to hear clearly.
To adjust the level of a channel, press this button once. If the desired channel 
is not displayed on screen and in the front-panel Message Display, use the 
Tuning Buttons to scroll to it. When the desired channel appears, use the 
M N
 
Navigation Buttons to change the level.
It is recommended that you avoid changing the channel levels after you have 
run the EzSet/EQ setup procedure described in the Initial Setup section, which 
properly adjusts all channel levels. See the Advanced Functions section for 
more information on manual speaker setup, including level adjustment.
Remote IR Sensor: This sensor receives infrared (IR) commands from the 
remote control. It is important to ensure that it is not blocked. If covering 
the sensor is unavoidable, use an optional Harman Kardon HE 1000, or other 
infrared receiver, connecting it to the Remote IR Input on the AVR 160’s rear 
panel.
Digital Input: To change the audio input for the current source to one 
of the six digital audio inputs or the analog input for the source, press this 
button and use the 
M N
 Navigation Buttons to change the input. Although 
any digital audio input may be assigned to any source, the analog audio 
inputs are all permanently dedicated to the source with which they are 
labeled.
M N
 Navigation: These buttons are used to navigate the AVR’s menus.
Set: Press this button to select the currently highlighted item.
Message Display: Various messages appear in this two-line display 
in response to commands and changes in the incoming signal. In normal 
operation, the current 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.
Tuning: Press these buttons to tune a radio station.
