This is a simple matter of taking hold of the jumper and sliding it straight upward,
then centering it over pins 2 and 3 and sliding is straight
downward. If you intend to use BIG BOOST™ only with a
rechargeable 9-volt nickel-cadmium battery (as it is packaged),
you do not need to do anything with the jumper.
Our BIG BOOST™ can be used with both model 96 and
our new model 97 kits. Although BIG BOOST™ is not a required
component for our standard kits, it is especially useful if you run
your trains consistently at low speeds. As the battery falls below its optimal point, BIG
BOOST™ pushes the voltage to charging level to keep your system operating a peak
performance. Even if you run your trains "all the time," BIG BOOST™ lets you forget
about the battery and still have great sound each time you start up. If you decide to
store your BIG SOUND™ for awhile, we recommend that you store it fully charged.
There is no need to disconnect the battery. It's a good idea to charge your battery
every six months for 6–8 hours and avoid letting the charge fall to zero.
A dedicated BIG BOOST™ can be wired into a five-volt LGB smoke unit, if you
wish to have smoke at lower voltage. (The smoke unit in your Spectrum™ Shay is
not a five-volt unit; you would have to retrofit the LGB smoke unit into your Shay.)
BIG BOOST™ can also be wired into your lighting system to activate it at lower
voltage and help keep the lights constant. One dedicated BIG BOOST™ can be used
for both smoke and lighting systems. DO NOT USE YOUR SOUND SYSTEM'S BIG
BOOST™ WITH OTHER ACCESSORIES. If a smoke unit is wired into the dedicated
sound system booster, the system's battery will keep the smoke unit ON and HOT
with the chance of ruining your engine or causing more serious hazards. And your
system's battery would eventually drain completely, defeating the primary function of
the booster.
BIG BOOST™ can be purchased separately—with complete wiring instructions—
from your favorite hobby shop or directly from Phoenix Sound. Your kit contains a
copy of the wiring instructions to provide more detail about BIG BOOST.™
