For example, to change the line build-out to 399 to 533 feet, while in Switchpack
Mode, set position 6 OFF and positions 4 and 5 ON.
NOTE:
The switch combinations for –7.5, –15, and –22.5 dB line build-out are not for
use with this product. Use of these settings will cause a weak signal and
degrade performance.
