RadioLink T7F-2.4Ghz Instruction Manual page 10

Transmitter battery voltage
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
lowbattery alarm will continuously beep until the transmitter is turned off. When the low-
battery alarm sounds, land immediately your model before losing control.
Note: 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 reaches 9.4 Volts.
Mixer alert warning (HELI only)
If the transmitter is turned on with the throttle hold or idle up function switched on, the screen
will show "MIX" and a warning will sound. Please turn the throttle hold and idle up functions
off to precede.
9.4 Volts - No more flying until recharge.
8.9 Volts - Land as soon as safely possible.
8.5 Volts - Emergency- Land immediately!
