3.6 Range check
Regular range checks are necessary for ensuring the reliable functioning of the
radio control system and for timely detection of changes in transmission properties.
Always perform a range check after:
installing, modifying or rearranging components in the model,
reusing components in the model that were involved in a crash,
irregularities when operating the model.
When performing a range check, the transmitting power is significantly reduced
enabling shorter distances between transmitter and model.
While the range check is active the status displays #2 to #8 show the flashing
message: RANGE! with the annular ring flashing red. An alarm tone is emitted in
all the status displays starting from #2 to alert the operator.
Recommended minimum distance: 40m to 100m, depending on receiver type. Refer
to the receiver operating instructions for detailed information.
Always perform a range check before starting up the model.
A second person must always be present for the range check to secure and observe
the model.
Large metal objects within or in close proximity to the checking range (wire fences,
cars) affect the result of the range check.
