Main Remote Control Functions

Preset Up/Down: When the tuner is in use, press these buttons to scroll through the sta- tions programmed into the AVR’s memory. When CD or DVD is selected using the Input Selector button 4, these buttons may function as Slow Fwd/Rev (DVD) or ”+10” (CD, CDR).

Clear Button: Press this button to clear incorrect entries when using the remote to directly enter a radio station’s frequency.

Memory Button: Press this button to enter a radio station into the AVR’s preset memory. Two underline indicators will flash at the right side of the Main Information Display ˜, you then have five seconds to enter a preset memory location using the Numeric Keys H. (See page 51 for more information.)

Delay Select Button: This button selects adjustments to the A/V Sync Delay and the indi- vidual channel displays. The first press of the but- ton displays an A/V SYNC DELAY message in the Lower Display Line ˜ and in the on- screen display, which means that you may change the amount of time that all channels are delayed together behind the video. This enables you to compensate for the loss of lip sync that may be caused by digital video processing in your display or by television stations. To change the A/V Sync Delay, press the Set Button F while the A/V SYNC DELAY message is visible and then use the ⁄/¤ Navigation Button E to change the setting so that the sound and the video image are in sync. To change the delay for an individual output channel, press the ⁄/¤ Navigation Button E until the desired chan- nel name is shown, and then press the Set Button F. Use the ⁄/¤ Navigation Buttons E to change the delay amount. (See page 35 for more information on delay options.)

Program Button: This button is used to begin the process of programming the remote. Press and hold this button for three seconds to place the remote in the programming mode.

Once the red LED under the Set Button F lights, release the button. You may then select from the desired option. (See pages 53-61 for more information on configuring the remote.)

Speaker Select: Press this button to begin the process of configuring the AVR’s Bass Management System for use with the type of speakers used in your system. Once the button has been pressed, use the ⁄/¤ buttons E to select the channel you wish to set up. Press the Set Button F and then select the speaker type (Large, Small or None) appropriate with the speaker in use. (See page 21 for more informa- tion.)

Volume Up/Down: Press these buttons to raise or lower the system volume.

EzSet/EQ Button: Press this button to turn the filters used by EzSet/EQ on or off. This allows you to hear the difference in system performance when EzSet/EQ is engaged or out of the signal path.

Channel Up/Down Selector: This button has no function when the AVR is being con- trolled, but when programmed for use with a VCR, TV, cable box, satellite receiver or other sim- ilar product it will change the channel up or down. See pages 53-61 for more information on programming the remote.

Mute: Press this button to momentarily silence the AVR or TV set being controlled, depending on which device has been selected. When the AVR remote is being programmed to operate another device, this button is pressed with the Input Selector button 4 to begin the pro- gramming process. (See page 53 for more infor- mation on programming the remote.)

Tone Control Button: This button controls the tone mode settings, enabling adjustment of the bass and treble boost/cut. You may also use it to take the tone controls out of the signal path completely for “flat” response. The first press of the button displays a TONE IN message in the Lower Display Line ˜ and in the on-screen display. To take the controls out of the signal path press either of the ⁄/¤ Navigation Buttons E until the display reads TONE OUT. To change the bass or treble settings, press the button again until the desired option appears in the Lower Display Line ˜ and in the on-screen display and then press either of the ⁄/¤ Navigation Buttons E to enter the desired boost or cut setting.
