DSC / Direct Servo Control
The acronym "DSC" is a carryover which stands for
the original "Direct Servo Control" function. However,
in HoTT systems the "direct servo control" function
is no longer available via a diagnose cable due to
technical reasons.

Charger jack
The
mc-20
HoTT transmitter's charger jack becomes
accessible after turning the left face-side cover away.
The transmitter's rechargeable LiIo battery can be
charged by way of the charger socket located behind
a cover on the left, front side of the transmitter – as
viewed from the front – with the included plug-in
charger (order no. 32032.4).
Maximum permissible charging current with Graupner
automatic chargers: 1.5 A.
Never use plug-in chargers from other manufacturers
or chargers intended for other battery types. Charger
output voltage which is too high or possibly even
different plug polarity, see further below, can cause
immense damage.
More information about charging the transmitter's
battery can be found on page 16. Observe the
safety notices on pages 7 … 9 when handling lithium
batteries.
