The SFX004 can be used in a

stand alone configuration as well.

In these situations just connect

pins 9 and 10 to the track and

address the device normally.

If the sound does not start in the decoder

1. Make sure you have selected the locomotive on a throttle. The sound will

not run unless the locomotive is addressed in the system.

2. Check your installation to make sure the decoders are installed properly.

If the sound output sounds distorted

1. Check the speaker cone for magnetic debris that may have collected there.

Debris on the speaker will cause a loss of sound quality and must be removed.

2. Be sure that the CV58 volume is not set at a level that is too high for the

speaker. For impedances below 32ohms (e.g. 8 to 30 ohms) set the volume set-

ting lower to ensure the 1 watt output rating is not exceeded.

If the sound in your decoder shuts down after you stop it and you are not

using a Digitrax system for control. On some DCC systems decoders are not

addressed by DCC packets after the locomotive is set to 0 speed. In this case

after the CV11 timeout elapses (6 second default), sound will "shutdown.". To

defeat this feature, set CV11=00 to remove the timeout and shutdown. To make

sounds, the decoder must have a command addressed to it at least once.

If you have trouble reading back CV's on the programming track, this may

be due to insufficient current draw by the SFX004 for the programmer you are

using. Of course you can always just re-program the CV value into a CV to

get the desired results, even though reading CV's does not work. OPs mode is

recommended for programming all CVs except CV01, CV17 & CV18 (2 digit

and 4 digit addresses). If a second DCC decoder is present that is not Sound

FX compatible, then correct readback of CV data is not possible, since the

NMRA CV readback method was not originally designed for multiple decoder

readback.

The SFX004 plays a Diesel scheme, but I want the default steam scheme. If
