Premier GP-7/9 Operating Manual

Operating & Programming Proto-Sound®

Programmable Features

As mentioned in the Basic Operating section, the engine is controlled by an

electronic DCRU® reverse unit that contains the standard

forward-neutral-reverse states found on most reverse units. However, when

power is first applied to the track, the reverse unit begins in RESET, similar

to a neutral state. Power must be interrupted again to get the locomotive to

enter the forward state. It is this first RESET state that gives Proto-Sound®

its unique, remote controlled functions.

Proto-Sound® is equipped with a microprocessor that allows the user to

utilize several remotely activated functions. In the simplest terms,

Proto-Sound® has its own “Computer" controlling these functions.

In order to access many of these remotely controlled functions, the unit

must be in the RESET state. RESET is entered anytime power to the

locomotive has been off for more than 3 seconds. When the engine first

enters RESET, the microprocessor initiates a system check to determine if

the system, transformer and engine are operating correctly. This takes

approximately 5 seconds during which you will hear the engine’s startup

sounds begin. In order for Proto-Sound® to properly initiate the system

check, do not advance the transformer throttle past 10 volts when you first

enter RESET, wait for the startup sounds to play, then slowly turn the

transformer throttle to the off position and back on again to enter forward.

Interrupting the power too quickly may cause the system to re-enter RESET

(signaled by two dings of the bell). Should this happen, wait longer before

interrupting the power to enter the forward phase.

Proto-Sound® comes with several programmable functions, including

remote Steam Chuff Volume Adjustment, Whistle In Neutral Operation,

ProtoCoupler® On/Off Control, Squeaking Brakes and Freight Yard Sound

Proto-Effects™. Each of these features is described in more detail in the

following sections. When in RESET, your engine will not respond as

normal to the horn/whistle or bell button. In fact, when in RESET only one

single bell chime will be heard each time the horn/whistle button is

pressed. If you don’t want to change your locomotives settings using any of

the programmable features, simply leave RESET (waiting 5 seconds before

interrupting the power) and put the engine into forward. Remember though,

that once power is turned off for more than 3 seconds, the next time power

is applied to the track, your engine will be back in RESET.
