System Set Up Procedure
This system was aligned at the factory and should not require additional adjustments to
achieve normal operation.
This Innovator CX Series system is of a drawer design with multiple boards inside the
drawer. If a board fails, that board needs to be changed out with a replacement board. The
failed board can then be sent back to Axcera for repair. NOTE: Contact Axcera Customer
Service Department at 1-724-873-8100 or fax to 1-724-873-8105, before sending in any
board or module.
Refer to Figure 16. Check that the Auto/Man switch S1 on the ALC Board is in the
Automatic ALC position. (NOTE: The silkscreen is incorrect on Rev. A, B & C boards.
Auto position is with the bat to the left, toward J4.) Adjust R75 the ALC pot on the ALC
Board as needed to attain 100% output power. Switch to Manual Gain (Manual ALC) and
adjust the Manual Gain pot R62 for 100% output power. Switch the ALC Board back to
Automatic ALC.
