OPERATION

Now that you have installed your system components and completed

a basic configuration of your receiver, you are ready to begin enjoying

your home theater system.

Turning On the AVR 254

Gently press the Master Power Switch until the word OFF is no longer visi-

ble. The Power Indicator above the two power switches should light up in

amber. This indicates that the AVR is in Standby mode and is ready to be

turned on. Normally, you may leave the Master Power Switch in the ON

position, even when the receiver is not being used. See Figure 41.

There are several ways in which the AVR 254 may be turned on:

a) Press the Standby/On Switch on the front panel. See Figure 41.

b) Using the remote, press the AVR Power On Button or any of the

Source Selectors. See Figure 42.

To turn the receiver off, press either the Standby/On Switch on the front

panel, or press the AVR Power Off Button on the remote. Unless the

receiver will not be used for an extended period of time (for example,

when are on vacation), it is not necessary to turn off the Master Power

Switch. When the Master Power Switch is turned off, any settings you

have programmed, including system configuration and preset radio

stations, will be preserved for up to four weeks.

IMPORTANT NOTE: If the PROTECT message ever appears

in the Message Display, 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.

Volume Control

The volume may be adjusted either by turning the knob on the front

panel (clockwise to increase volume or counterclockwise to decrease

volume), or by pressing the Volume Control on the remote. See Figure 52.

The volume is displayed as a negative number of decibels (dB) below

the 0dB reference point.

Unlike the volume controls on some other products, 0dB is the maximum

volume for the AVR 254. Although it’s physically possible to turn the

volume to a higher level, doing so may damage your hearing and your

speakers. For certain more dynamic audio materials, even 0dB may be

too high, allowing for damage to equipment. We urge caution with

regard to volume levels.

You may change the volume level display from the default decibel scale

to a 0-to-100 scale by adjusting the Volume Units setting in the System

Settings menu, as described on page 52.

Mute Function

To temporarily mute all speakers and the headphones, press the Mute

Button on the remote. See Figure 52. Any recording in progress will

not be affected. The MUTE message will appear in the display as a

reminder. To restore normal audio, either press the Mute Button again,

or adjust the volume. Turning off the AVR will also end muting.

Sleep Timer

You may program the AVR to play for up to 90 minutes and then turn

off automatically using the sleep timer.

Press the Sleep Settings Button on the remote, and the time until

turn-off will be displayed. See Figure 53. Each additional press of the

Sleep Button will increase the time until turn-off by 10 minutes, up

to a maximum of 90 minutes, then the SLEEP OFF setting appears,

which disables the sleep timer.

Figure 53 – Sleep Settings Button

When the sleep timer has been set, the front-panel display will automati-

cally dim to half-brightness. If you press any button on the remote or

front panel, the display will return to full-brightness. The display will dim

again several seconds after your last command.

If you press the Sleep Button after the timer has been set, the remaining

time until turn-off will be displayed. You may press the Sleep Button to

change the time until turn-off.

Audio Effects

Depending on your preferences or the specific characteristics of your

listening room, you may wish to adjust some of the audio settings, such

as tone controls, to improve performance. Access these settings from

the Audio Effects submenu, as described in the Advanced Functions

section.

It is not necessary to adjust the Audio Effects settings to enjoy your

new AVR. We recommend leaving the settings at their default values

until you are more familiar with your system.

Video Modes

The settings in the Video Modes menu are used to fine-tune the

picture if necessary after making all adjustments on the video display.

It is recommended that you leave the settings at their defaults. See the

Advanced Functions section for detailed information.

Headphones

Plug the 1/4" plug on a pair of headphones into the headphone

jack on the front of the receiver for private listening. See Figure 54.
