1. Introduction
The LokSound 5 DCC decoder by ESU is a versatile digital decoder
integrating a full-featured, 10 channel sound system, various
lighting outputs and a 1.5A motor controller. This key component
of your newly acquired “DD-1” is responsible for all functions,
such as motor control, control of all lighting functions and all
sound and special sound functions.
The decoder supports DCC with RailComPlus. It can also be used
on analogue DC systems.
The “DD-1” is preset at the factory for immediate operation. Nev-
ertheless, we kindly ask you to first read these instructions before
you set this locomotive onto a powered track.
Important warnings:
• This LokSound decoder is designed for use in GHB “DD-1”only.
• Do not expose to wet and humid conditions.
• Do not remove the heat shrink sleeve on the decoder.
• Always disconnect the circuit when installing the decoder.
Please install the body shell before applying voltage.
• To avoid risk of short circuit, ensure that opens ends of wires do
not come into contact with any metal parts of the Locomotive!
• Make sure that no wires are squeezed or cut by the model’s
transmission parts when reassembling the locomotive.
• Handle the speaker with extreme care: Do not touch the mem-
brane or apply pressure!
