5.2.2 Selecting procedure example (Multi-point mode)
Four channels specification of MA900 is used in the procedure example for explanation, but
the same setting procedures also apply to MA901. However, the 8-channel specification
applies to the MA901. Therefore, refer to procedure examples by replacing the 4-channel
specification for the MA900 with the 8-channel specification for the MA901.
