频率微调
***特别注意*** D8和D16协议接收机在正式使用之前，必须使用频率微调功能，消除发射机与接收机
之间的频率误差，才可达到最佳遥控距离与稳定性，具体操作方法如下：
1.将RF Freq.fine tune数值逐渐调低，直到接收机丢失信号，并记录下这个数值(一般为负数)
2.再RF Freq.fine tune数值逐渐调高，直到接收机丢失信号，并记录下这个数值(一般为正数)
3.将这两个数字按此公式计算，得出频率微调中点值，并填写在RF Freq.fine tune参数中
(低位数值+高位数值)÷2=中点值
例如：得到低位数值为-73，高位数值为35，根据公式计算

D8 and D16 compatible receivers MUST be frequency fine tuned before flight.
Once the radio is bound to the receiver:
Return to the RF Freq. fine tune option
1. Lower the value until the radio loses the connection with the receiver. Record the value (TUNE_MIN).
2. Raise the value so that the connection is restored, then continue to raise it until the radio loses the
connection with the receiver again. Record the value (TUNE_MAX).
3. Calculate the median between the two values (TUNE_MIN + TUNE_MAX) / 2 = TUNE_MEDIAN
4. Set RF Freq. fine tune to the median value
Example
Connection is lost at -73 and +35; the median is -19:
Once the Fine Tuning value is known, it can be used for all models which use the same protocol.
