Fail Safe

What to do in case of a malfunction
In the basic transmitter display, use a finger or the
provided stylus to touch the gear icon labelled "B":

In comparison to classic PPM technology, the system-
related greater reliability of the HoTT system is because
the microprocessor in the HoTT receiver can process
both undistorted signals from its transmitter as well as
distorted control signals. Only when the signals are
excessively distorted or garbled, for example from noise,
the processor replaces them with control signals that
are saved in the receiver depending on the settings
described below. This allows intermittent disturbances
such as drops in field strength, etc. to be overlooked
which would otherwise lead to familiar "wobbles". When
this occurs, the red LED on the receiver shines during
the interference.

When a receiver is delivered, all outputs are
set to "hold" by default. This default can be
individually changed for all receiver outputs

The "Fail Safe" function determines the response of the
Trim Step
receiver when there is an interruption in transmission
from the transmitter to receiver. Receiver outputs
1 ... 9 of the mz-18 HoTT transmitter and 1 ... 12 of
the mz-24 HoTT transmitter can optionally retain their
momentary position...
1. ... ("HOLD").
In case of transmission interruptions, all servos
programmed to "hold" remain at their position which
was last identified as correct until a new, correct
control signal is received by the receiver.
2. ... move to a freely selectable position ("F/S")
after a delay when there is an interruption in the
transmission.
To switch between "HOLD" and "F/S", touch the button
in the "Mode" column in the line of the channel to be
switched to with a finger or the provided stylus, for
example:

After switching to "F/S", in the "SET" column touch,
with a finger or the provided stylus, one of the value
fields that appears upon switching to "F/S" such as the
value field that appears in the "CH1" line:

Move the control element for this control channel into
the desired position and, with a finger or the provided
stylus, touch the button at the bottom right of the
