WARNING & ERROR DISPLAYS 
An alarm or error indication may appear on the display of your transmitter for several reasons, including when the 
transmitter power switch is turned on, when the battery voltage is low, and several others. Each display has a unique sound
associated with it, as described below.
MODEL SELECTION ERROR:
 Warning sound: 5 beeps (repeated 3 times)
The
MODEL SELECTION
 warning is displayed when the transmitter attempts to load a model memory from a memory
module (optional CAMPac) that is not currently plugged into the transmitter. When this occurs, model No. 01 is 
automatically loaded.
'RQRWÀ\ XQWLO WKH SURSHUPRGHO LV ORDGHGLQWRPHPRU\ Reinsert the memory module, 
and recall the desired setup using the model select function. 
LOW BATTERY ERROR:
 Warning sound: Continuous beep until transmitter is powered off.
The
LOW BATTERY
 warning is displayed when the transmitter battery voltage drops below 8.5V.
Land your model as soon as possible before loss of control due to a dead battery. 
MIXER ALERT WARNING:
 Warning sound: 5 Beeps (repeated until problem resolved or overridden) 
The
MIXER ALERT
 warning is displayed to alert you whenever you turn on the transmitter with 
any of the mixing switches active. This warning will disappear when the offending switch or 
control is deactivated. Switches for which warnings will be issued at power-up are listed 
below:
ACRO
:Throttle cut, idle-down, snap roll, airbrake 
GLID
%XWWHUÀ\FRQGLWLRQV
HELI
:Throttle cut, throttle hold, idle-up
If turning a switch OFF does not stop the mixing warning: When the warning does not stop even when the mixing switch
indicated by the warning display on the screen is turned off, the functions described previously probably use the same
switch and the OFF direction setting is reversed. In short, one of the mixings described above is not in the OFF state. In 
this case, reset the warning display by pressing CURSOR LEVER. Then change one of the switch settings of the mixings 
duplicated at one switch.
BACKUP ERROR:
 Warning sound: 4 beeps (repeated continuously)
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.
[Note] At this warning display, the transmitter transmits in 
PPM
 mode even if the set-up mode is 
PCM
 mode.
Do not fly when this message is displayed: all programming has been erased and is not 
available. Return your transmitter to Futaba for service. 
MEMORY MODULE INITIALIZE DISPLAY
This warning appears when an (optional) CAMPacPHPRU\PRGXOHLVXVHGLQWKHWUDQVPLWWHUIRUWKH¿UVWWLPH:KHQWKH
MODE BUTTON is pressed, initialization of the module begins, after which the memory module can be used. Once the 
module is initialized, the display will not appear again. 
The 10C CANNOT convert data from other radio types (i.e. 8U, 9Z). Installation of a CAMPac with data from another 
radio type will result in reinitialization of the CAMPac and loss of all data. 
RF MODULE WARNING:
 Warning sound: A single long beep. The single beep lets you know that the RF module has been 
removed from the transmitter, or is not being read properly. The green RF light also goes out.
