USING THE POWERED F-3 B-UNIT WITH
PFA/FYS EQUIPPED MTH F3 AA OR ABA
You can utilize the PFA/FYS that came equip on previous MTH Premier F3
AA or ABA by reading the following instructions. Refer to your Premier F3
AA or ABA for operation instruction of PFA/FYS. Your MTH Premier
Powered F3 B-unit has a DCRU installed in it, which is not directly connected
to the ProtoSound of your powered A unit. Because the Powered B-unit is not
directly connected to the ProtoSound, the Powered B-unit will cycle its
directional states while the ProtoSound A unit is playing the PFA/FYS events.
To operate the Powered F-3 B-unit with your ProtoSound A unit, the only
thing to remember is not to set the voltage on the transformer too high, not
above 8-10 volts. If the voltage is set to high, the Powered B-unit will begin
vibrating on the track, as its motors will be turning. Since the directional
cycles of the DCRU are insink with the number of events played during the
PFA/FYS, the Powered B-unit will start in the same direction as the
ProtoSound A unit after the PFA/FYS has finished playing.
