Can handpieces be used on all ports of the FX-973 simultaneously?

The FX-973 can use nine types of handpieces, including a desoldering tool, and they can be connected to any of its three ports. However, if two or more handpieces from [Group A] are connected, one of them will enter standby mode and cannot be used at the same time.
If only one or less handpiece from [Group A] is connected, all handpieces can be used simultaneously across all ports.
