desired speed has been set, press the button to save the tickover value into memory. The
engine sound ceases. Return the joystick to the neutral position to exit set-up mode.
(3) TOP SPEED –regardless of its previous state, the engine begins to run at top speed
and this may now be adjusted by use of the throttle channel joystick. When the desired
speed has been set, press the button to save the top speed value into memory. The
engine sound ceases. Return the joystick to the neutral position to exit set-up mode.
(4) CYLINDER COUNT - regardless of its previous state, the engine begins to run at a
medium speed and the number of cylinders may now be adjusted by use of the throttle
channel joystick. Assuming the joystick is initially at ‘neutral’ then a brief push in the
forward direction will increase the cylinder count by one. Return to neutral and push
forward again to further increase the cylinder count. Trying to increase beyond the
maximum count of six causes a short ‘beep’ to be issued and the count rolls round to the
minimum cylinder count value. Similarly, brief pushes to the reverse direction decrease the
cylinder count. When the desired cylinder count has been set, press the button to save the
cylinder count value into memory. The engine sound ceases. Return the joystick to the
neutral position to exit set-up mode. After setting the cylinder count, the tickover and top
speed settings may benefit from re-adjustment to suit the changed character of the engine.
If the user has a forward only set-up, then the joystick cannot be pressed in the reverse
direction to reduce the cylinder count so a reduction can only be achieved by forward
presses to roll over the maximum value and then advancing from the minimum value so
reached.
(5) ENGINE ‘VOICE’ - regardless of its previous state, the engine begins to run at a
medium speed and the ‘voice’ or sound character of the engine may now be adjusted by
use of the throttle channel joystick in the same manner as employed for cylinder count
adjustment in (4) above. When the desired ‘voice’ has been set, press the button to save
the ‘voice’ value into memory. The engine sound ceases. Return the joystick to the neutral
position to exit set-up mode. After setting the engine ‘voice’, the cylinder count, tickover
and top speed settings may benefit from re-adjustment to suit the changed character of the
engine. If the user has a forward only set-up, then the joystick cannot be pressed in the
reverse direction to step backwards through the voices so this can only be achieved by
forward presses to roll over the final voice and then advancing from the first voice so
reached.
(6) IDLING TIME-OUT - regardless of its previous state, the engine stops and the LED is
on for one second. Following this the LED gives a brief flash at one second intervals,
accompanied by a ‘tick’ sound, where each ‘tick’/flash represents 5 seconds of timeout
duration. Press the button at the desired duration to save the timeout value into memory.
Pressing the button during the initial one second that the LED is on sets the timeout value
to zero –this is principally intended for use with the steam sound so the engine stops
immediately the throttle is closed but it may be set for all engine types –equally, users
