SVS 2000Default Procedure 1

• Use CAUTION when performing this procedure (Press ENTER after each step)– From RUN Select Function 94– DEFAULT SYSTEM– DEFAULT NVRAM?– ARE YOU SURE?– Perform normal “Quick Config” procedure.

SVS 2000Default Procedure 2

• Use CAUTION when performing this procedure– Hold the ENTER key– Cycle Power– Release the ENTER key– Perform normal “Quick Config” procedure.

SVS 2000Signal Processor

• Quick Config– Complete Table 3-1 Information– Default Unit– Use ENTER key to cycle through steps and

enter required information– Perform live load (Auto Cal) calibration when

installation constraints permit.
