The SRM 66 and SR 1L have been discontinued. Some accessories are still available.
The MRS 4 provides a simple solution to recalling Memories from a remote location for products having an MRP (Memory Recall Port) or a VIP (Versatile Input Port).
The MRS 4 is intended for use in Normal mode, allowing up to 4 Memories to be recalled by contact closure. These are radio buttons: engaging one button (in, changing to green) causes any of the other three to disengage (out, changing to black). Space is provided next to each button for labelling.
