Description of Change: 108-2398 Grade Control Boxes now carry two additional setup screens on the latest version box 3.8. These changes are to accommodate the use of a SAS (Sonic Averaging System) system not available through Caterpillar. This system utilizes multiple sonic sensors with the use of an averaging leveler

The added setup screens are as follows:

1. SS; This option is found in the Performance Menu and is used when a number of trackers are selected for use over a leveler. The setting for Caterpillar/Barber-Greene paver application in the setup screen is set in the OFF position.

2. OIN; This option is found in the technician's Menu and is either ON or OFF. This function allows the current to be reversed to the valve. The setting for Caterpillar/Barber-Greene Paver application in the setup screen is in the OFF position.
