Installation instructions
Warranty card
Tools also needed for the installation procedure include: regular
and cross-point screwdrivers, tweezers, and soldering station
with a maximum soldering temperature of up to 30 watts /
300˚Celsius / 572˚Fahrenheit with a fi ne tip, soldering fl ux for
electronics (0.5 - 1 mm / 0.02" – 0.04" diameter), de-soldering
braid or a de-soldering pump.
Safety Notes
• WARNING! Sharp edges and points required for operation.
• Do wiring and assembly work only on a voltage-free or
grounded work mat. Failure to do this can lead to dangerous
static charge from your body and to damage to the compo-
nents.

• Operate the decoder only with the authorized voltage (see
technical data).
There is a danger of burning yourself when working with a
soldering station.

Functions
The mSD SoundDecoder is a sound decoder with very extensive
setting and adaptation possibilities. Additional sound functions
are available. This decoder can be updated. The requirement for
this is an appropriate controller Central Station (60213 – 60215),
software Version 4.0 or higher and/or Programmer 60971).
The settings and digital functions can only be used in digital
operation. However, the same possibilities are not available in
all protocols.
