a. Operation frequency: 2402- 2480MHz, total 79 frequencies (the space of close
frequencies is 1 MHz)
b. FHSS transmitter mode
c. Output power≤4Mw
d. Channel: 4 proportional
e. Operation voltage: 4.8V
f. Operation current＜25mA
2. Using Guide
a. Power on the transmitter, the voltage of the battery no less than 4.8V, all the 3 LED s
(from left to right: red, yellow and green) illuminated; when the voltage of the battery
between 4.4V-4V, green light off; when the voltage below 4V, just the red light on, and
then we must charge the battery with the included charger. Please review the attached
circuit diagram of the charger.
b. As the diagram 1 shown, the top transmitter case has 2 control sticks, and their
performance as following:
Left stick,
