Both my Sears garage operator and my Door King gate operators use the 315MHz
rolling codes system and the receiver manual says it has two modes: one for
15 remotes in high security mode and the other for 31 remotes in normal mode.
I don't recall which way I set the jumpers on my LiftMaster 312HM receivers.
