Programming procedure
The "Fail Safe" function determines the behavior of
the receiver if communication between the transmitter
and the receiver is disrupted. Receiver outputs 1 ... 8
mc-16
on the standard eight-channel
mc-16
mitter, or 1 ... 12 on the
HoTT transmitter
with twelve channels (unlocked as an extra-cost op-
tion) or the standard twelve-channel
transmitter can optionally ...
1. preserve the current position ("hold"):
If communication is disrupted, all servos pro-
grammed to "hold" mode remain at the positions
judged to be the last valid positions by the recei-
ver until the receiver picks up another valid control
signal, or
2. move to a freely selectable position ("Pos") if in-
terference should occur, following the expiry of the
"time delay".
Use selection keys on the left or right four-way
button to select the desired servo connection 1 ... 8
(
) or 1 ... 12 (
) then briefly tap the center
of the right four-way button to freely switch between
"hold" ( ) and "Pos" mode ( ):

Following this, use the selection keys on the left
or right four-way button to select the "DELAY" option
shown at the bottom of the display ...

... and then briefly tap the center
four-way button. Now use the four-way button's selec-
tion keys to make your choice from the four possible
HoTT trans-
time delays (0.25 s, 0.5 s, 0.75 s and 1 s) offered.
A simultaneous tap on the or selection keys
mc-20
of the right four-way button (CLEAR) will reset the
HoTT
inverse video field to its default value 0.25 s.
Afterwards, select the STO field at the bottom right of
the display with the selection keys on the left or
right four-way button. Now put the servos which have
been switched into position mode into their desired
positions SIMULTANEOUSLY with the respective
operating elements.
Briefly tap the center
button to store these positions as the fail-safe setting
for the receiver, so that it can revert back to them if
interference is experienced.
Successful storage of the positions is confirmed
briefly on the screen:

Ensure you make use of this safety net by at
least programming the following for a fail-safe
incident: for glow-powered models, set the mo-
tor throttle position to idle; for electric mod-
els, set the motor function to stop, or "Hold"
for helicopter models. If interference should
occur, the model is then less likely to fly off on
its own and cause damage to property or even
personal injury. Consider asking an experi-
enced pilot for advice.
