8000i System Operation Manual – Addendum.
Please note that the Range Shift feature as described in the Sounder sections of
the 8000i System Operation Manual is not implemented.
The benefits of this feature are very similar to the sounder Zoom Range, and
Zoom Range Shift features, which are available.
