Basic Operation
Balance Control
The
BALANCE
control lets you adjust the sound balance between the left and
right speakers. If you properly position the speakers and your listening area is
centered between them, the center control setting is usually best (see “Position-
ing Speakers” on Page 5).
For an unusual speaker placement, adjust
BALANCE
as follows:
1. Select
TUNER
. Then press
FM/AM
to select the FM band.
2. Press
FM MONO
so MONO appears. The sound is monaural instead of ste-
reo, so each speaker delivers the same output.
3. Turn
BALANCE
until you hear the sound coming equally from each speaker
when you are in the listening area.
4. Press
FM MONO
so MONO disappears from the display.
Loudness Control To increase the high and low ranges of sounds for improved audio at a low lis-
tening level, press

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 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.
