USING YOUR SE THE FIRST TIME
Turn it on and select a sound
Press the
POWER
button and the SE will initialize and
start playing in about two seconds. The SE may be
turned off with the POWER button, or the
TIMER
button
(see
Sleep Timer
).
The SE will retain the last settings used when you last
powered it off using the POWER button. If you power it
off by unplugging the SE power adapter from the wall
outlet, the settings may not be saved.
Next, use the dial to select a sound category, and
then press the
SELECTION
button to choose between
the four sound environments in that category.
See the included
Sound Environments Guide,
or the
sound listings on pages 5–6, for a complete list of
sound environments.
Use the
VOLUME
buttons to adjust the volume to
your liking.
Not all the sound environments are designed for sleep.
Some environments are designed for relaxation, speech
privacy, meditation, or studying and reading.
Adaptive Mode
The SE can adapt to noise in your environment. It uses
its built-in microphone on the front panel to listen for
disruptive noises, and raises the volume and/or adds
enhancing sounds to the sound environment to
compensate. Press the
ADAPTIVE
button to turn it
on or off . The lamp next to the ADAPTIVE button will
indicate when it’s active.
When Adaptive Mode is not active, your SE will maintain
a steady volume level.
Adaptive Mode allows the SE to be customized to suit
your personal preferences and situation. You might
prefer a quiet, steady sound, especially if there is little
noise, or steady noise, in your environment. Or, you might
need the additional noise masking that Adaptive Mode
provides. Experiment to fi nd the setting you like best for
diff erent situations.
Note:
When setting the volume in Adaptive Mode you
are actually setting the maximum volume it can reach
when it detects a loud noise. If the sound seems too
low when it is quiet in your room, turn the volume up
to a higher base level.
MORE USEFUL FEATURES
Sleep Timer
The Sleep Timer can be used to set the SE to play for
a number of minutes and then shut off gradually and
automatically. The time interval can be set to 30, 60,
90, or 120 minutes by pressing the
TIMER
button.
Turning off the SE clears the Sleep Timer. Pressing the
TIMER button when the SE is off will turn it on and set
the Sleep Timer to 30 minutes. Pressing the TIMER
button again will advance the timer to the next interval.
After 120 minutes has been selected, pressing the TIMER
button again turns the timer off .
Headphone Jack
A standard 3.5mm stereo headphone jack is located on
the bottom of the connector panel. Any ordinary set
of headphones or earbuds with a 3.5mm connector may
be used. Connecting headphones or earbuds disables
the SE’s built-in speaker, so it’s a great way to use your
SE for private relaxation.
As with any product, use common sense when using
headphones. Avoid using them at high volume levels.
Prolonged exposure to loud volume levels may impair
your hearing.
External Audio Input
You may use the external audio input to listen to an
audio source from any device with a standard 3.5mm
headphone or line-out connector. An audio cable is
included, or you may use your own.
Some phones and other devices may generate noise
if they are simultaneously being charged and used as
an external audio source.
Caution:
It is best to connect the audio source
with care:
1. Turn the volume down on your SE
2. Connect one end of the audio cable to your
sound source
3. Connect the other end of the audio cable to the
audio input jack on the SE
4. Adjust the SE volume to the desired listening level
USB Charging Ports
The SE connector panel has two USB-A charging ports.
Please note that these may be used for charging
a smartphone or similar device. The charging ports are
not used for data or audio.
Turning Off the Display
You may use the
DISPLAY
button to turn off the front
panel lamps if they’re a distraction. If you adjust any
settings while the display lamps are off , they will turn on
for 15 seconds and then dim again.
