Manual of Two-Way Radio System www.FrSky-rc.com P5of9
For safe operation, it is necessary to perform pre-flight range check.
Caution must be paid when you perform check in an environment with metal fences,
concrete buildings, or rows of trees. Loss of signal may be experienced.
Perform a range check as follows (Note: this would be done with the receiver
installed in the model):
a) Place the model at least two feet (60cm) above non-metal contaminated ground;
for example a wooden bench.
b) Place the receiver’s antenna apart. Do NOT let the antenna touch the ground.
c) Place the antenna of the transmitter in a vertical position.
d) Turn on the transmitter and receiver.
e) To enter Range Check Mode, press and hold the “F/S Range” button of the
transmitter for 4 seconds, the RED LED of the transmitter module will be turned off, the
effective distance will be decreased to 1/30.
f) Walk away from the model while simultaneously operating the controls on the
transmitter, confirm that all controls are completely and correctly operational at least 30
meters away.
g) Press the “F/S Range” button for 1S-4S, the transmitter will exit Range Check
Mode.
7. Safety range indicator
The Two-Way Radio System has a feature to show the RSSI (Received Signal
Strength Indication) of the receiver. When the RSSI is low, the Tx module will issue
three types of alarms.
Red: The receiver is very far from the Tx.
Orange: The receiver is sound, but would be far from Tx.
Yellow: The receiver is sound,
Green: The receiver is OK.
Note: Due to many environment factors, there may be casual alarm.
