Modify the parameters as necessary, and then select OK once
complete.
 DAC Gain Choose the method for managing the
amplification of the analog signal that returns to the sensor:
− Auto Select this option to allow the monitor to
automatically optimize the amplification of the signal.
− Manual Select this option to enter a fixed value
between -12db (lower amplification) and +12db (high
amplification) at which to amplify the signal.
 Surcharge Detection Select the Disable checkbox to
prevent the monitor from implementing the Surcharge
Detection function when processing smart depth data. For
locations that typically do not experience surcharges,
disabling Surcharge Detection eliminates the processing
time required for this function and, as a result, conserves
monitor power.
