KEY INPUT AND DISPLAY3
When the transmitter battery drops below 9.0 volts,
the display will start to flash BAT and an audible
alarm will sound for 8 beeps. These warnings mean
you should land your aircraft immediately.
Note: During the period that the battery alarm
is flashing, the input buttons will not
function. If you are currently in the
function mode, the transmitter will exit
automatically and return to the normal
display (see Section 5.1).
