3.Select the video channel you want to configure using one of the following keys on the numeric keypad:

Channel Command	Key
Select Channel 1 For Adjustment	<1>
Select Channel 2 For Adjustment	<2>
Select BOTH Video Channels	<0> (Channel 0)

Use Channel 0 to tune both video channels simultaneously. This simplifies the procedure for setting up large dual-head installations where a consistent cable type is used and the adjustments required should be almost the same.

4.Reset the selected channel(s) by pressing:

<Left Control> + <Home>

5.Step through the Assisted EQ settings to find the level that gives the best image.

Assisted EQ Command	Key Sequence
Next Assisted EQ Setting	<Left Control> + <PgUp>
Previous Assisted EQ Setting	<Left Control> + <PgDn>

Assisted EQ steps through a table of preset LF & HF EQ values for 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.
