When used with the RailKing Remote Lock-on (sold separately), Loco-Sound-equipped
engines gain Proto-Cast
™
and Proto-Dispatch
™
features.
Proto-Cast:
This feature allows you to play audio recordings through your engine’s
speakers. You must supply the audio source (a small portable is sufficient) and a
male-to-male mini cable (1/8” plug, like that used for the headset with a portable CD/tape
player) to connect your audio source to the remote lock-on. To use Proto-Cast, simply
plug the mini-cable into your audio source (usually into the headphone jack) and into the
“Audio” port on the right side of the remote lock-on and adjust the volume.
Proto-Dispatch:
This feature allows you to broadcast your own voice through your
engine’s speakers. You must supply the microphone and a mini cable (1/8” plug, like
that used for the headset with a portable CD/tape player) to connect your microphone to
the remote lock-on. To use Proto-Dispatch, simply plug the mini-cable into the
microphone and into the “Mic” port on the left side of the remote lock-on and speak into
the microphone.
When these features are in use, the locomotive’s own sounds (engine sounds and bells,
whistles, and horns) will be muted so that only the sounds you broadcast will be heard.
Because these two features are voice activated, there will be a 10-15 second delay after
you stop speaking into the microphone or turn off the audio source before the engine
sounds resume. To stop using the feature and return to normal operation, unplug the cable
from the lock-on jack.
If using parallel tracks with multiple Loco-Sound-equipped engines, Proto-Cast and
Proto-Dispatch transmissions from one track may be picked up by the other nearby
engines.
If you experience popping and interference, try cleaning the track with denatured alcohol
as described in the “Cleaning the Wheels, Tires and Track” section of this booklet.
Using Proto-Cast and Proto-Dispatch Features
not change direction (including going into neutral) until you repeat the 1 horn, 3 bells
code to return the engine to its normal condition, even if the engine is kept without power
for extended periods of time.
