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.
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, snap roll, airbrake HELI :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 both S
ELECT BUTTONS simultaneously. 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.
Do not fly when this message is displayed -all programming has been erased and is not
available. Return your transmitter to Futaba for service.
