6) TELEM function: battery voltage, receiver voltage, signal strength, unit temperature Auto binding: All of the Crossover-rx receivers have a really awesome auto-binding function. The receiver will enter the binding mode automatically after power is applied and it doesn’t receive a transmitter signal for 15 seconds. This is indicated by the slow flashing blue LED light changing to a rapid flash. The receiver is now in the binding mode, complete the binding operation according to your transmitter’s binding instructions.

TELEM function:

The TELEM function monitors battery voltage, receiver working voltage, signal strength, as well as working temperature in real time. 

NOTE: The effective control range of the TELEM function depends on the transmitter, it is quite often that the working range of the receiver is far more than TELEM function effective range.
