Plug the other end of the DSC cord into another XP9303 transmitter while holding the
ENT button and prepare that transmitter for Transmit as described above. Or, plug the
other end of the DSC cord into a DataSafe unit and prepare the DataSafe for Transmit.
2. Highlight and select TRANSFER in the SYSTEM Menu to obtain the Transfer display.
3. If RECEIVE is already displayed, continue with the next step. If TRANSMIT is
displayed, highlight and select TRANSMIT, changing it to RECEIVE.
4. Select the model memory that is to receive the data by highlighting and selecting the
Model Memory number/name and then scrolling to and selecting the model memory that
is to receive the data. Be careful to select an unused model memory or a memory that
contains data for a model that is no longer needed because the data in this model memory
is going to be replaced by what is transmitted and will be permanently lost.
5. When all is well, press the button next to CLR /START on the left side of the display.
"Stand-by" appears at the bottom of the display indicating that the XP9303 is ready to
receive data. Press START on the other XP9303 transmitter or DataSafe unit to begin the
data transfer to the XP9303.
TRIM STEP
The Trim Step function provides for adjusting the sensitivity or resolution of the XP9303 trim
levers and trim switches. It is useful during and after initial trimming of the aircraft in order to
trim the aircraft quickly at first and then to make very precise adjustments to aircraft trim. The
digital trims may have a setting of 0-10 with 10 being the coarsest adjustment. The table below
lists the number of trim increments, each side of center, for each Trim Step setting.
Trim Step Number of Trim Increments
0 0 (aircraft cannot be trimmed with trim lever)
1 100
2 50
3 34
4 25
5 20
6 17
7 15
8 13
9 12
10 10
Note: When set to 0, the trim levers cease to function and can no longer be used to change the
trim of the aircraft.
When adjusting the digital trims (AILE, ELEV, RUDD, FLAP, AUXT) the total trim travel does
not change – only the number of increments (beeps) changes which makes for finer or coarser
trim resolution/movements.
