Turning on/off engine sound
The USM-RC-3 can only play an engine sound, if it has been switched on before.
There are different ways to switch on the engine sound:
Using a proportional channel (X2/2 - X2/8) to switch on engine sound:
The engine sound can be switched on and off via a control on the radio (stick / slider
/ switch / rotary potentiometer). The corresponding receiver output must be
connected with a servo patch cable to a proportional input (Prop # 2 - # 8) of the
sound module.
The proportional channel must be configured in the Sound-Teacher under
Configuration
Proportional channels
Function “Engine sound on/off“. If the
proportional channel is brought in this area (A –D), the engine sound is switched on
or off.
Using nautic-mode on proportional channel #3 (X2/3) and #4 (X2/4) to switch on
engine sound:
If you have a nautic swich unit installed in your receiver, you can assign the function
“engine sound on/off" to a nautic switch (Configuration
Nautic/multiswitch) to turn
the engine sound on or off with the selected switch (see page 44).
Using EKMFA-mode on proportional channel #3 (X2/3) to switch on engine
sound:
With the One-channel multi-function selection (EKMFA) you can nearly control the
whole sound module with only one free channel of the transmitter. “Counting” (and
pressing the joystick a corresponding number of times) is used to determine, which
function is triggered. In the Sound-Teacher you can set up, how often the joystick
must be pressed, to turn on/off the engine sound (see page 77).
Switch on the engine sound via the switching inputs X1/3 - X1/6:
The engine sound can also be switched on via the switching inputs at terminal X1/3 -
X1/6. To do this, one of the switching inputs in the Sound-Teacher must be assigned
with the function "Engine sound on / off" (see page 85). If the input is now connected
to battery minus (eg with a switch or a switching module), the engine sound is
switched on.
Turn on engine sound automatically by motion:
Is this option activated, the engine sound is switched on automatically, as soon as
you accelerate the first time (that means for example moving the joystick out of the
neutral position) (see page 69). The engine sound keeps switched on as long as you
are driving. If the model is stopped, the engine sound will be turned off after an
adjustable time (e.g. 10 seconds). If you start driving again, the sound will be
switched on again. This method has the advantage, that no additional channel (or
switch) in the transmitter are needed to activate the engine sound.
