Range
A range check should be done at the field when the model is ready to fly.
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.
Currently TD MODE in range check mode provides range check data for one receiver at
a time on the 2.4G link and one receiver at a time on the 900M link. If you have three
2.4G receivers registered and bound as Receiver 1, 2 and 3, one of the receivers will
be the active telemetry receiver and its number will be displayed by the RX sensor as
0, 1, or 2. That will be the receiver that is sending the RSSI and VFR data. If you turn
that receiver off the next receiver will become the active telemetry receiver in a
priority of 0, 1, and then 2. Each of the three receivers can be range checked by
turning off the other receivers.
RX sensor 0 = Receiver 1
RX sensor 1 = Receiver 2
RX sensor 2 = Receiver 3
Please also refer to the Telemetry section for a discussion on
values.
At this point the receiver is registered, but it still needs to be bound to the transmitter
to be used.
