Replacing QD75 system is recommended.
When replacing the existing AD71 (S1/S2/S7) with "QD75P/QD75D", refer to
Technical Bulletin "FA-A-0060: Procedures for Replacing Positioning Module
AD71 with QD75".
Mount AD70D to the QA6B-type extension base unit.
Otherwise, replacing with the QD75M system is recommended.
Replacing with two QD73A1 modules or QD75 system is recommended.
