What is Special About this Machine?
Adaptive Mode and Manual Mode
In Internal Audio Mode (when no Audio Cable is attached) the Adaptive
Button switches between Adaptive Mode and Manual Mode. The light next to
the Adaptive Button is on in Adaptive Mode and off when in Manual Mode.
In Adaptive Mode, nomad adapts to noise in your room. It listens for
disruptive noises and raises the volume and/or adds enhancing sounds
(richness) to the SoundStory when it detects intrusive noises.
In Manual Mode the unit still listens but does not significantly change its
volume in response to noise. Instead, it maintains a relatively constant
volume level determined by the Volume Up/Down Buttons.
Richness
Richness adds character to each SoundStory by dynamically mixing sounds
to avoid repetition. The Richness Level controls how the sounds are mixed.
(See Page 7 for usage of the Richness and Adaptive Buttons in External Audio mode)
Richness may be set to one of four levels in Internal Audio Mode:
High: These SoundStories are the most complex. For example, in the
OCEAN setting, the sound of a fog horn or barking sea lion is occasionally
heard. In the RAIN setting, a thunderclap is often heard and wind is more
prevalent. In the BROOK setting, frogs croak.
Medium: Moderate sounds are incorporated into the SoundStory. For
example, in the OCEAN setting additional sounds such as bird song are
played but they occur less often than in the High Richness Level.
Low: Designed for sleep, the SoundStory will play at a steady, continuous
level. OCEAN: mostly wave sounds with a few soft birds, BROOK: no frogs
Off: Designed for the most sensitive sleepers, the SoundStory will play at its
most consistent level. Few, if any, additional sounds are included.
Note: The NOISES SoundStory settings operate with Richness off. Accordingly, for
the NOISES SoundStory only, the Richness Level selects the SoundStory variant to
be played: Off: BROWN NOISE, Low: PINK NOISE, Medium: WHITE NOISE, High:
ELECTRIC FAN.

Using Richness and Adaptive Features
The Richness and Adaptive Buttons allow the unit to be customized to suit
personal preference and each situation. You might prefer a quiet, steady
sound and use Manual Mode, especially if there is little noise, or steady
noise, in your environment. However, you might need the additional masking
that Adaptive Mode provides or prefer a more lively sound mix created by
the higher levels of Richness. Experiment to find the settings you like best.
Note: When setting the volume in Adaptive Mode you are setting the
maximum volume it can reach when it detects a loud noise. Turn it up!

Useful Features
Sleep Timer
Turning On nomad with the Power Button results in continuous play, until
the Sleep Timer is turned on. In Internal Audio mode the Sleep Timer sets
nomad to play for some number of minutes and then gradually shut Off.
In External Audio mode the Sleep Timer becomes a “two-stage” timer. The
Sleep Timer can shut Off nomad gradually or switch to Internal Audio Mode
when it expires. nomad can play music for a while, then automatically switch
to your favorite SoundStory; either all night or for 30 or 60 minutes. The
Richness Button in External Audio Mode sets the Timer Mode (see page 7).
For example, if you are listening to music in External Audio Mode and set
the Timer to 90 minutes, with the Timer Mode set to “01” (right Richness light
is on), nomad will play your music for 90 minutes. It will then slowly ramp
down the music and switch to Internal Mode, slowly ramping up and playing
whatever SoundStory you have selected, for 30 minutes. After that, nomad
will gradually go Off. See Table (“nomad
Behavior When Timer Expires “) at
the top of page 7 for a listing of the various two-stage Sleep Timer options.

External Audio Mode
When no Audio Cable is plugged in to nomad it is in Internal Audio Mode.
When an Audio Cable is plugged in, the unit automatically switches to External
Audio Mode and nomad can be used to listen to an external audio source. This
allows you to listen to an MP3 player, PC audio, movie soundtrack, or any other
audio source from any device with a standard headphone or line-out connector.
A standard 3.5 mm stereo Audio Input Jack is located on the upper
right side of the nomad unit (Audio Cable supplied). Simply
connect the headphone jack, or line-out jack, of the audio source to
the Audio Input Jack on the nomad with the supplied Audio Cable
and adjust the volume to your liking. When you remove the Audio
Cable, nomad switches back to Internal Audio Mode and plays the
selected SoundStory. Please note that volume and other settings
are maintained and saved separately for External Audio Mode and
the two Internal Audio Modes (Adaptive Mode and Manual Mode).
In External Audio Mode the Adaptive Button can be used to increase the audio
input level 6 dB. If you turn the Boost on (Adaptive light on), and the audio
material sounds distorted, you should turn the Boost off. The Boost may be
automatically disabled if operating nomad with weak batteries.
In External Audio Mode press the Richness Button to set the desired Timer
Mode. This controls the behavior of nomad after the Sleep Timer expires.
CAUTION: It is best to connect the audio source with care: 1) Turn nomad
volume down 2) Connect one end of Audio Cable to sound source 3) Connect
other end of the Audio Cable to the nomad Audio Input Jack 4) Turn on 6 dB
Boost if desired 5) Adjust the nomad volume to the desired listening level.
Display Lights
When any button is pressed or the Audio Cable is inserted or removed, the
lights on the front panel will come on and then automatically go off after 30
seconds in Internal Audio Mode or 5 seconds in External Audio Mode. In
Internal Audio Mode you can choose to have the lights on all the time. To do so,
when you turn the nomad unit On, press and hold the Power Button down for
about 2 seconds until the Timer lights go on then release the Power Button.

Power Options
The nomad unit contains a sophisticated power management system. This
convenient and unique system allows you to power nomad in a variety of
ways, provides for battery only operation, has battery backup capability, and
extends the life of batteries used to power the device. The four options are:
1. Use two (2) “AA” batteries (install in bottom of nomad unit)
2. Use the supplied Power Adapter and Power Cable
3. Use both 1 and 2 above (battery backed up AC power)
4. Use the supplied Power Cable only (connect to laptop, etc.)
When you plug in the Power Cable and have the batteries installed, the
system will only draw power from the Power Cable unless the power is
interrupted. At that time the nomad power automatically switches to the
batteries providing true battery back up. The audio from the nomad unit will
not pop or click during the switchover. If the batteries become too weak to
operate the device at the current volume level, the volume level is
automatically and gradually reduced. This extends the useful life of the
batteries, and eliminates jarring sounds from being produced when the
batteries die under all but the most extreme cases. In general, nomad will
automatically and quietly shutoff when the batteries are exhausted (Battery
Shutdown) and the Battery Level will not be displayed (see Table below).
Note: User Settings will not be saved during a Battery Shutdown.
Battery Backup
The nomad power management system uses the AA batteries if there is an
AC power failure. When used for this purpose battery life is up to four years;
however, ASTI recommends you change the batteries every year or two to
minimize the possibility of battery leakage damaging your nomad unit.
Note: When you operate the nomad unit from batteries only, perhaps
because an AC outlet is not available, the batteries are supplying power to
the nomad system and will last for a time determined by many factors
including mode of operation, volume settings you use, and battery quality.
Battery Level Codes
The SoundStory lights indicate the battery status for approximately 3 seconds
when nomad is turned Off (only if nomad has been On 10 seconds or longer).
