Futaba 6J F4103 Data Sheet

In addition to the model type, the LCD screen also displays the transmitter battery 
voltage. When the voltage goes below the Battery Low Voltage alarm setting, the 
{+ |  '## =    #'$+  # '##  #  +! # 
transmitter is turned off.  When the low battery alarm sounds, immediately land your 
model before losing control.

NOTE: If the transmitter ever reaches this battery voltage alarm, land as soon as safely as possible.  A

throttle hold and/or idle up functions off to proceed.  

The Backup error warning occurs when the transmitter memory is lost for any reason.  If this occurs, all of 
the data will be reset when the power is turned on again.

   when this message is displayed: all programming has been erased and is not available. Return 
your transmitter to Futaba service.

Anytime you wish to view or change any of the current settings in the transmitter, the programming mode

for approximately one second.  Once in the program, the MODE or END key will be used to scroll through 
each of the available functions/features.  The MODE key will scroll one direction while the END key will 
scroll in the opposite direction.  Therefore, if when scrolling through the functions, if the modeler bypasses 
the desired function, press the opposite key to scroll back to the bypassed function.  For example, if using the 
MODE key to scroll and the desired function is passed, press the END key to scroll to the desired function.
