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 LEDs do not respond to F0:
1. Be sure the locomotive address you are using to send the command is actu-
ally the address programmed into the decoder.
2. Make sure you have good electrical connections between the FN04K1 to the
SDH104K1A. We recommend soldering these connections for best reliability.
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 on the programming track, this may be
due to your system using Direct Bit mode for Service Mode readback. This cre-
ates difficulty reading two decoders in a locomotive that may have different
data or responses. Since the SDH104K1A and FN04 are actually two decoders,
you'll need to use standard direct mode for reading back CV values on the pro-
gramming track. Of course you can always just re-program the CV value into a
CV to get the desired results. OPs mode is recommended for programming all
CVs except CV01, CV17 & CV18 (2 digit and 4 digit addresses).
