How to change 22 / 11ms frame frequency on RX1202

Hello

My RX1202 has frame frequency set to 22ms by default.
How could i change it to 11ms ?

Is 11ms setting compatible with DJI Nava v2 ?

Many thanks for your help,

I finally found how to proceed :

11 Millisecond frame rate : for digital servos ( Green light on RX1202 )
22 Millisecond frame rate : for analog servos ( Red light on RX1202 )

After binding completed and RX powered on :

Press & hold the switch for approx 5s / 6s
Both indicators will turn on.

Release the switch & press it again :
The frame rate can be changed alternatively : the LED will turn red or green only depending on frame mode selected.
