Sound selection play by a 3 position switch (toggle switch)
This control mode need a toggle switch with neutral position (recommended), or a common proportional channel.
Selecting a sound or function:
The desired sound (e.g sound #3 or function) is selected by pushing the switch/stick 3 times from its neutral position to high position (>1.8ms).
The selected sound/fuction is triggered/played by pushing the switch/stick to low position (<1.2ms).
The last selected sound/function can be triggered multiple times, without new selection.

Teaching the sound unit for toggle switch / joystick control
1. Power on transmitter and receiver. LED blinks fast -> normal mode. Bring throttle stick to minimum and control the center position of the toggle switch.
2. Bridge Learn contract about 0.5 seconds until beep -> LED cont. on. At this moment all neutral positions are stored.
3. Move throttle stick to your desired acceleration point (throttle stick position where idle dead band stops and engine running sound starts) and push the switch/joystick of the control channel once. -> A short sequence of acceleration is played. Now the dead (neutral) band of the speed channel is defined.
4. Move the throttle stick to full speed position and push the switch/stick of the control channel again (like pos.3). -> A short sequence of full speed is played. After this the sound unit is back in the normal operation mode. All special sounds can be controlled as mentioned above.

Sound/Function preset for Siku Lanz Eil-Bulldog RC Tractor:
1.Engine sound start/shut down (pushing the switch/stick 1 time from its neutral position to high position)
2.Horn (pushing the switch/stick 2 times from its neutral position to high position)
3.Front LED on/off (pushing the switch/stick 3 times from its neutral position to high position)
4.Front LED blink (pushing the switch/stick 4 times from its neutral position to high position)
5.Front LED flash (pushing the switch/stick 5 times from its neutral position to high position)
6.Rear LED on/off (pushing the switch/stick 6 times from its neutral position to high position)
7.Front and Rear LED blink (pushing the switch/stick 7 times from its neutral position to high position)
8.Volume up (pushing the switch/stick 8 times from its neutral position to high position)
9.Volume down (pushing the switch/stick 9 times from its neutral position to high position)
