Optimus 31-3042 Using Headphones, Muting the Receiver, Loudness Control, Listening Safely

Basic Operation

Using Headphones

To listen with headphones (not supplied), insert the headphones’ 1/4-inch plug into the receiver’s front panel PHONES jack. To silence the speakers and listen with headphones without disturbing others, press SPEAKER so only SP appears on the display.

Listening Safely

To protect your hearing, note the following when using headphones.

•Set the volume to its lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level.

•Do not listen at extremely high volume levels. Extended high- volume listening can lead to permanent hearing loss.

•Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.

Muting the Receiver

To temporarily mute the sound, press MUTING on the remote control. --MUT- ING --appears. Press MUTING again to restore the audio level.

Loudness Control

To increase the high and low ranges of sounds for improved audio at a low lis- tening level, press LOUDNESS (or LOUD on the remote control) so LOUDNESS appears. Press LOUDNESS (or LOUD) again to turn off this feature.

Bypassing the Sound

Controls (Remote Control

Only)

To bypass your receiver’s sound controls (BASS, TREBLE, BALANCE, or any spe- cial sound options) so you can hear the audio at its original tonal quality (for example), press DIRECT on the remote control so DIRECT appears. Press DIRECT again to turn off this feature.

Note: When you turn off the bypass feature, you will have to reselect any desired special sound options (see “Using Advanced Sound Options” on Page 21).
