Fail-Safe/Hold
The Fail-Safe/Hold function is available only when you use the
transmitter in either of the
These features are designed to help minimize the damage to your
helicopter during a loss of signal to the receiver. The servos either
assume the fail-safe presets or hold their last good signal position.

Accessing and Utilizing the
Fail-Safe/Hold Function
To access the Fail-Safe/Hold function, enter Code 77 at the code
number access selection or use the direct mode method.
Note: Since the actual screen appearance varies, depending
on the modulation of your radio, refer to the appropriate modu-
lation section that follows.

maintains the position held immediately before the interference
was experienced. When a clear signal is restored, the Hold func-
tion releases and control of the helicopter returns to you.
Fail-Safe
Note: Fail-safe should always be set when the helicopter is
not running.
When the Fail-Safe function is activated and the signal is inter-
rupted, the transmitter automatically moves each servo to a pre-
set position. The position that each servo assumes is determined
by you, as is the time length of the interference that must occur
before servo movement.
After the interference has ceased, control of the helicopter
returns immediately to you.
There are three time delays to choose from: .25 sec, 0.5 sec, and
1.0 sec. These time delays are the amount of time it takes, start-
ing the moment the interference occurs, until the servos assume
their preset positions.
To select the preset servo positions and the time delay, access
