Firmware Update - GRAUPNER mx-20 Hott Programming Manual

capable of operating up to 12 servos.
In order to achieve the greatest possible
fl exibility but still preclude unnecessary
inadvertent operator errors, control channels 5 ...
12 have not been assigned to any controls. This
means that servos connected by way of these
channels will remain in their middle positions
until an operator element has been assigned.
Practically all mixers are initially inactive for
this same reason. More about this can be found
on page 96 (winged aircraft) or 100 (helicopter
models).
• The fundamental procedure for initial
programming of a new model memory location
can be found on page 60 and the programming
examples that begin on page 236.
• When the remote control system is switched on,
being bonded or when making settings, that the
transmitter's antenna is always far enough away
from the receiver's antennas. If the transmitter's
antenna is brought too close to the receiver's
antennas this will cause receiver over-modulation
and its red LED will illuminate. At the same
time the return channel will drop out and, as a
consequence, the fi eld strength indicator in the
transmitter's screen will be replaced by an "x" and
the receiver's current battery voltage display will
show 0.0 V. The remote control is then in Fail-Save
mode, see page 196, i. e. when signal reception
drops out all servos will remain in their current
positions until a valid signal is again received.
In such a case, increase the distance (between
the transmitter and the model containing the
receiver) until the indicators are again "normal".
