Trim Step
To access the System Menu List (SYSTEM M.), start with the transmitter switched off. Press the ENT (Enter) key and
while holding it down, switch the transmitter on. The System Menu List is displayed. Rotate the Scroll Bar to highlight the
"TRIM STEP" menu choice and click it to bring up the sub menu. The Trim Step screen appears.
The Trim Step function enables the sensitivity of the Digital Trims to be adjusted between zero (Digital Trim inhibited) and
10 steps per beep. Note that the setting only adjusts the coarseness of the Trim and that the total trim adjustment range
stays the same.
With a normal Trim, trim input moves the entire stick movement range by the amount of the trim input. A special Limited
Stroke Trim (L.S.T.) system is available for the Aileron, Elevator and Rudder and when activated, the trim affects only the
centre range of stick movement. The end points are not changed by the trim input.
The screen display will depend on the model type selected.
To set a trim step value, highlight the required primary channel by rotating the Scroll Bar and click on it to bring up the
sub menu. The figure is surrounded by a box to indicate that it is selected. Rotate the Scroll Bar to alter the setting. When
the required setting is achieved, click the Scroll Bar to exit the sub menu. To return the figure to the default of 4, press the
clear (CLR) key at the left hand side of the screen.
To select Limited Stroke Trim, select the primary channel adjacent to "Type" by rotating the Scroll Bar and click on it to
toggle between L.S.T. and Normal. The black indicator square moves between the bottom of the box (NORMAL) to the
top of the box (L.S.T.) to indicate the current selection. The selection toggles between the NORMAL and L.S.T. positions
with each click.
Press the LIST key to return to the System Menu List. Press the enter (ENT) key to return to the Information Display
Screen.
Device Select (Helicopter)
To access the System Menu List (SYSTEM M.), start with the transmitter switched off. Press the ENT (Enter) key and
while holding it down, switch the transmitter on. The System Menu List is displayed. Rotate the Scroll Bar to highlight the
"DeviceSEL" menu choice and click it to bring up the sub menu. The Device Select screen appears.
The Device Select Menu is used to define the switches or Digital Trims used to control the Auxiliary Channels, to enable or
disable the normal output of a channel and to allocate the switches used to control the additional Flight Modes. When a
channel is inhibited, it becomes available to be used as a Slave in a Programmable Mixer.
To activate the additional Flight Modes, highlight F.MODE EXTRA by rotating the Scroll Bar and click on it to bring
up the sub menu. The activation switch choices are surrounded by a box to indicate activation. Select the required
additional Flight Mode activation switch by rotating the Scroll Bar and click on it to exit the sub menu. To inhibit the
additional Flight Modes, click on INH. When additional Flight Modes are active, further Trim, Dual Rate and other choices
appear in various main menus.
