The Model Seven contains an internal battery pack
that continuously biases some of the crossover compo-
nents. The battery pack is mounted on the crossover
board and has a life expectancy of 12+ years. Like all
Model Seven components, the battery pack should be
changed at the factory (remove the entire cross over).
Please do not attempt to measure the output of the
battery pack. The measurement process will drain
the batteries more than several months of normal
use.
You should contact your dealer or Vander-
steen Audio regarding changing the battery
packs. Date of Change:
If you do not feel you have the technical expertise to disassemble and reassemble the
speaker modules, you should have your Vandersteen dealer or a competent techni-
cian perform the work.
