The menu tree below shows how to navigate through the 
TQi transmitter’s various settings and functions. Press and 
hold MENU to enter the menu tree, and use the following 
commands to navigate through the menu and select options. 

MENU:

   When you enter a menu, you always start at the top. Press 

MENU to move down the menu tree. When you reach the 
bottom of the tree, pressing MENU again will return you 
to the top.

SET:

  

Press SET to move across the menu tree and select 
options. When an option is committed to the 
transmitter’s memory, the status LED will rapidly blink 
green.

   Press both MENU and SET to go back one level in the 

menu tree.

EXIT:

  

Press and hold MENU to exit programming. Your selected 
options will be saved.

ECHO:

   Press and hold SET to activate the “echo” function. Echo 

will “play back” your current position on the Menu Tree, 
should you lose your place. For example: If your current 
position is Steering Channel End Points, holding SET will 
cause the LED to blink green twice, green once, and then 
red three times. Echo will not alter your adjustments or 
change your position in the programming sequence. 

MENU TREE

Below is an example of how to access a function in the menu 
tree. In the example, the user is setting the Multi-Function knob 
to be a steering Dual Rate control.

To set the Multi-Function knob to control STEERING DUAL RATE (%):

1. Switch the transmitter on
2. Press and hold MENU until the green LED lights. It will blink in single intervals.
3. Press SET. The red LED will blink in single intervals to indicate Steering Dual 

Rate has been selected.

4. Press MENU twice. The red LED will blink three times repeatedly to indicate 

Steering Percentage has been selected.

5. Press SET to select.  The green LED will blink 8 times fast to indicate  

successful selection.

6. Press and hold MENU to return to driving mode. 

Note: The transmitter is “live” during programming 
so you can test the settings real time without having 
to exit the menu tree.
