In a monitoring system, when there is an evaluation that a product is defective, in a solder print inspecting device that is subject to monitoring, that information is sent to a mobile terminal possessed by an operator. The operator who views the notification performs, through the mobile terminal, a checking task for evaluating whether or not the evaluation result regarding the printed substrate that has been evaluated as a defective product is correct. Depending on the evaluation result, an operating instruction is sent to the solder print inspecting device, which has temporarily stopped the printed substrate. If correction information instructing that the defective-product evaluation be corrected to a non-defective-product evaluation is sent from a mobile terminal to the solder print inspecting device, the solder print inspecting device corrects the defective-product evaluation to a non-defective-product evaluation, and releases the temporary stop of the printed substrate.
