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
on the standard eight-channel
mc-16 HoTT trans-
mitter, or 1 … 12 on the mc-16 HoTT transmitter
with twelve channels (unlocked as an extra-cost op-
tion) or the standard twelve-channel mc-20 HoTT
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 SET key
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 SET key of the right
four-way button. Now use the four-way button’s selec-
tion keys to make your choice from the four possible
time delays (0.25 s, 0.5 s, 0.75 s and 1 s) offered.
A simultaneous tap on the  or  selection keys
of the right four-way button (CLEAR) will reset the
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 SET key of the right four-way
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:

Attention:
• Please note that decisive fail-safe settings are
stored in the receiver! Therefore, following a
change of receivers, these fail-safe settings
should be renewed and in the previous receiv-
er they should be erased, if necessary per Re-
set, see page 60.
• 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.
