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).
