INSTALLATION

Refer to the instructions that came with your Kato F40 locomotive for

removal of the body shell, [there are one locking tabs in the rear of the

loco that must be unlocked to remove the shell. Refer to the two pictures

in figure 1]. Gently insert an Exacto Knife blade between the body shell

and chassis to unlock these tabs. Remove the original circuit board by

very carefully removing the plastic clip and sliding the PCB out. Don’t lose

the clip. There are two wheel pickup contact strips. These strips must be

wrapped with tape approx. 1/4 wide (as shown in the image below) to

prevent them from touching the motor leads. Trim off some material from

the plastic cradle under the motor lead area to compensate for the tape

thickness. After applying the tape and trimming the plastic, reinstall the

strips. Now, install the decoder in place of the original PCB and reinstall

the plastic clip you removed earlier. Apply a strip of tape over the clip &

down the chassis sides to help hold the decoder in place. Re-install the

body shell. Now your loco is ready to go to work on your railroad.

When you complete the decoder installation, we strongly recommend building a

test track with a 27 ohm resistor to limit current. Only test your installed decoder

on the test track. The test track may prevent damage from an incorrectly installed

decoder. A Program Track is not a test track.

TEST

All MRC decoders have been factory programmed with address #3, 28/128

speed steps and maximum top voltage. Never run the installed decoder on

your layout without first successfully running on test track. Otherwise,

you may damage the decoder if it is not wired correctly or if you have not

properly isolated the motor, chassis and lights.

To test, place the loco on the test track. Select the “Run” mode of your DCC

system and select or acquire address #3. Move up the throttle and the loco

should move forward. Push the light button [F0] and the front headlight should

come on. Change the direction of the loco and the loco should change direction

and the rear headlight (if equipped) should come on. The loco cannot reach full

speed, due to the resistor. If all above occurs, you passed the test. Congratula-

tions!

If your installed decoder does not pass the test, find the problem, correct it and

test it again.

OPERATION

The decoder has start up and shut down features. If the loco was previously

shut down you have to start up the engine. Press any function key to start up

the engine before operating the loco. To shut down the engine you must bring

the loco to idle and then press F8 three times.

Double click F0 will turn on/off sound (CV49). You can’t turn off horn which is

always on. The decoder has four types of diesel prime movers, plus “off”. You

can use F12 to select this feature or use CV 123. You can use F19 to select 34

different horn sounds and use F18 to select 8 different bell sounds. With MRC

Prodigy Advance

DCC which has 28 functions, you can easily setup and access

all the decoder’s functions. If your DCC System is limited in functions or can not

program CV’s you may not be able to access all the features of this decoder.

With some DCC Systems you will have to use CV programming to set up the

decoder.

The decoder default is set to automatic notch. You can program CV122 to 3 for

manual notch for realistic operation. And then use F9 to notch up and use F8 to

notch down.

There are many more program features available with this decoder. Please refer

to the CV Chart to explore other features of the decoder.

The decoder can also be operated by a regular DC power pack. This will give

you synchronized engine sounds only. If you wish to enjoy the full array of

sound functions using your DC power pack, the MRC Blackbox (item #0001050)

for DC operation will allow you to control all of the sounds in your sound

equipped locomotives. And, the MRC Blackbox is easy to setup and use.

CAUTION:

The decoder must be isolated as shown. Apply electrical tape or plastic

equiv.) tape in the areas shown in red to prevent the electrical contacts

from touching the chassis and damaging the decoder.

Note2: when CV122=3 (manual notch up/down, F8 will notch down and F9 will

notch up.

Bell, Dynamic Brake and Rail Wheel Clack cannot play at the same time. If you

activate the Bell sound [F1], while either the Dynamic Brake or Rail Wheel Clack

sounds are in use, the Bell sound will override the other 2 sounds. Rail Wheel

Clack cannot play while the loco is in idle. When you turn off Dynamic brake

and Rail Wheel Clack sound there will be one second delay.
