adequate operational range.
We have installed a special “Power Down Mode” in the T8J in order to perform an operational ground range 
check.  During this mode, the RF power is reduced in order to test the operational range of the T8J.  
To activate the Power Down Mode and Perform A Range Check:
1) To activate the “Power Down Mode” please hold down the JOG KEY and then turn the transmitter switch 
on. A power mode screen comes out. JOG KEY is pushed where Power Down is chosen. When this mode is 
active the Purple LED on the Lighting front of the transmitter will provide users with an audible and visual 
indication that the transmitter is in the “Power Down Mode”. 
Audibly, the transmitter will beep one time every three seconds. Visually, the LCD screen will display 
“POWER DOWN MODE”.  The words “POWER DOWN MODE” will blink as an additional reminder that 
the transmitter is in the “Power Down Mode”.
2) With the “Power Down Mode” activated, walk away from the model while simultaneously operating the 
  
control.
3) If everything operates correctly, return to the model.  Push END KEY and complete power down mode. 
Set the transmitter in a safe yet accessible location so it will be within reach after starting the engine.  Be 
certain the throttle stick is all the way down, and then start the engine.  Perform another range check with 
your assistant holding the model and the engine running at various speeds.
