Tx Battery Monitoring

The Tx battery alarm is now configurable in the System ⭢ Extra ⭢ Tx Bat menu:

Current firmware has no longer a battery gauge in the upper right corner of the main screen, a voltage reading is being displayed instead.

It is possible to change voltage alarm threshold to any number. The value can be adjusted to use 1S/2S LiPo batteries. If you use NiCds or NiMH, you can lower the voltage threshold to whatever you feel is best.
