HELI 92
When the Fail-Safe Function is activated (i.e., when the signal is
interrupted), the transmitter automatically moves each servo to a
preset position. The position that each servo assumes is
determined by you, as is the time length of interference that must
occur before servo movement.
After the interference has ceased, control of the airplane returns
immediately to you.
There are three time delays to choose from: 1/4 (0.25) second,
1/2 (0.50) second and 1.0 second. These time delays are the
amount of time it takes, starting the moment the interference
occurs, until the servos assume their preset positions.
Setting Fail-Safe/Hold Memory in Z-PCM Modulation
1. After accessing the Fail-Safe Function, it is time to adjust the
Fail-Safe presets.
2. Select among the three time delays (1/4, 1/2 or 1.0
seconds). To do so, simply press the + or - key until the
appropriate delay appears on the screen.
3. Hold the transmitter sticks in the position that you want the
servos to assume during signal loss conditions. You can
determine fail-safe preset positions for the other channels by
placing the potentiometers and switches in the positions that you
want them to assume during interference.
4. With the sticks, switches and potentiometers in the fail-safe
positions, touch the CLR key. This will enter these locations as the
fail-safe memory settings. A high pitched beep will indicate that
this setting has been stored.
5. To confirm that the input of data was successful, switch the
transmitter OFF. The controls will move to the input locations. If
not, repeat step 4 again.
6. To exit the Fail-Safe Function, press the UP and DN keys
simultaneously.
Note: These preset positions remain stored in the transmitter’s
memory until both the transmitter battery pack and the lithium
back-up battery have been removed (or until data reset has been
performed). Therefore, you do not have to reset the fail-safe
each time you fly. Should you want to re-adjust the fail-safe
presets, access the Fail-Safe Function and adjust the presets as
you have just done. The transmitter automatically recalls the
settings for the last fail-safe adjustment.
Accessing the Fail-Safe/Hold Memory in S-PCM Modulation
Hold (S-PCM)
The Hold Function is automatically activated when the radio is
turned ON and in the S-PCM modulation.
This function stops (or holds) the servos in the positions they were
in just prior to the interference. Therefore, your airplane
maintains the position held immediately before the interference
was experienced. When a clear signal is restored, the Hold
Function releases, and control of the aircraft returns to you.
1. Place the transmitter power switch in the ON (upper)
position.
2. While the power switch is in the ON position, press the UP
and DN keys simultaneously to access the Function Mode.
3. Press either the UP or DN key until Fail-Safe appears in the
left portion of your LCD.
