Select Switch Designation

SAFE

Select technology can be easily assigned to any open switch (two or

three position) on the transmitter. With this new feature, you now have the ﬂex-

ibility to enable or disable the technology while in ﬂight.

IMPORTANT: Before assigning your desired switch, ensure that the travel for

that channel is set at 100% in both direction.

Assigning a switch

1. Bind the aircraft correctly to activate SAFE Select. This will allow the

system to be assigned to a switch.

2. Hold both transmitter sticks to the inside bottom corners and toggle the

desired switch ﬁve times (one toggle = full up and down) to assign that

switch. The control surfaces of the aircraft will move, indicating the switch

has been selected.

Repeat the process to assign a different switch if desired.
