Transmitter battery voltage
“Battery” icon
In addition to the model type, the LCD screen also displays the
transmitter battery voltage.
When the voltage goes below approximately
8.5 Volts
the “battery” icon will
flash
and the low-
battery alarm will continuously beep until the transmitter is turned off. When the low-battery
alarm sounds you will have approximately four minutes (or less) to land your model before
losing control. You should never allow the transmitter voltage to become this low while flying,
but if it does, land
immediately
.
Note
: When the transmitter voltage reads
8.9 Volts
you will
still have approximately ten minutes (or less) before losing
operational range, so this is the recommended
absolute
minimum
voltage. If the transmitter ever reaches 8.9 Volts,
land as soon as safely possible. A more reasonable margin
of safety would be to quit flying for the day (or recharge the
batteries) when the transmitter battery.
SUGGESTED GUIDELINES
9.4 Volts - No more flying until recharge.
8.9 Volts - Land as soon as safely possible.
8.5 Volts -
Emergency- Land immediately!
Mixer alert warning
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 and model
selection are Throttle hold switch or Idle-up switch.
Backup error
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 turn on again.
When the Backup error occurs, initialization starts from model number 6 to 1.
The model number on the left of the screen changes from 6 to 5, to 4, to 3, to 2, to 1, and
finally the number disappears. The disappearance of the model number indicates that the
initialization has been completed. Now you can turn off the power of the transmitter. Please
do NOT turn off the power during the initialization; otherwise initialization will restart when you
turn on the power.
Do not fly
when this message is displayed: all programming has been erased and is not
available. Return your transmitter to Futaba service.
