RailKing Doodlebug Electric Engine
PSA
Remedy
Once in PSA, the engine doesn’t go
into reverse.
When the PSA enters its last
sequence the bell automatically
comes on.
When PSA is enabled, pressing the
whistle and bell buttons has no effect.
I push the direction button but the next
sound clip in the sequence does not
play or the engine does not come out
of PSA after fourth press of the
direction button.
So that PSA effects can be as realistic
as possible,
Proto-Sound 2.0
disables the reversing unit
whenever PSA is enabled. This
way the engine remains still at its
stop as the operator cycles
through the PSA sequences.
PSA is programmed to start ringing
the bell at that point. After
approximately 12 rings of the bell, it
will automatically turn off.
Because PSA must control various
effects in each sequence, Proto-
Sound 2.0 takes control of these
sound effects until you exit PSA.
Each PSA clip must play for approx.
30 seconds before PSA will advance
to the next step in the PSA cycle. Wait
at least 30 seconds in each PSA
sound clip before pressing the
direction button.
Compatibility
This engine will operate on any traditional O-31 or larger O Gauge track
system, including M.T.H.’s RealTrax® or ScaleTrax™ or traditional tubular
track. It is also compatible with virtually most standard AC transformers.
(See page 17 for a complete list of compatible transformers and wiring
instructions.)
