different lengths of cable (in 80ft {25m} increments calibrated from 0 to
1250ft {375m}). Each time you enter Command Mode and start adjusting
Assisted EQ, the unit resets LF and HF values.
After finding the best setting, you will probably want to fine-tune the LF and
HF equalization settings (see steps 8&9). This is best done after adjusting for
any color skew as described below.
