4. Tap OK on the transmitter to end the Bind process, and power cycle the
receiver.
5. If the Green LED on the receiver is on, and the Red LED is off, the receiver is
linked to the transmitter. The receiver/transmitter module binding will not have
to be repeated, unless one of the two is replaced. The receiver will only be
controlled (without being affected by other transmitters) by the transmitter it is
bound to.
Warnings – Very Important
Do not perform the binding operation with an electric motor connected or an
internal combustion engine running.
Range check
Range check is activated by selecting 'Range check'.
A voice alert will announce ‘Range check’ every few seconds to confirm that you
are in range check mode. A popup will display the Receiver Number, and the VFR
% and RSSI values to evaluate how reception quality is behaving. When the
range check is active, it reduces transmitter power, which in turn reduces the
range for range testing. Under ideal conditions, with both the radio and receiver
at 1m above the ground, you should only get a critical alarm at about 30m
apart.
Please refer to the Telemetry section for a discussion on VFR and RSSI values.
