Setting equalization for input sources
High and low EQ levels for each input can be selected via
the Input EQ DIP switches on the front panel. Setting these
switches to High (up) compensates for a degraded/poor quality
signal, reducing the need for additional signal conditioning
equipment.
If the input signal is strong, set the switches to Low (down).
Resetting
To reset the switcher to its factory default settings,
1. Press and hold the Input 1 button while power is being
applied to the unit.
2. Continue holding the Input 1 button until the power-up
sequence completes.

Resetting restores the EDID to a resolution of 1024x768
@ 60 Hz.
