INSTALLATION

Repeat steps 2 and 3 for the other slave locations.

After all slaves have been aligned, remove the level meter.

This completes the alignment procedure.

NOTE:

Do not check the XMT levels at the slave location. These will be
9 dB below the system level when terminated at the slave XMT
test jacks. Using the slave XMT test points to try and set the
same level as the master will magnify and distort the signal
above a maximum level of -1 dB.
