5.  RECEIVER OPERATION

5.1.  LCD Display.

The receiver LCD display is shown below (Fig. 5b). Two-channel receivers
feature two LCDs, one for each channel. The display provides a snapshot
report of the condition of your wireless channel, including battery status infor-
mation sent from the transmitter by telemetry.

The right two-thirds of the display primarily shows status information regard-
ing the condition of your receiver channel, as follows:
