Allocation for Adjustment
Mode For adjustment mode, set the operation mode switch on the rear panel of the
Unit as shown in the following diagram. When the Unit is set for adjustment
mode, the ADJ indicator on the front panel of the Unit will flash.
The allocation of CIO words and bits is shown in the following table.
