+Starting with ExpressLRS v4.0.0 an additional Arming method is introduced. 
 
-The default arming method, via Channel 5 (Aux1), is the default, and still encouraged to be used by majority of FPV pilots using Betaflight, INAV or Ardupilot (and their respective derivatives like Emuflight, etc.). This will now be called **Arming Mode CH5**.
+The traditional Arming method, via Channel 5 (Aux1) driven by EdgeTX Channel Mixer 5 is the default and is still encouraged to be used by majority of FPV pilots using Betaflight, INAV or Ardupilot (and their respective derivatives like Emuflight, etc.). This will now be called **Arm using CH5**.
 
-The new arming method called **Arming Mode Switch** utilizes a switch on an EdgeTX radio. This switch can either be tied into a channel or not. What this means is that your Channel 5 will be free for other functions, like controlling gains on your stabilizer, or changing flight modes, or as another full proportional channel when using any of the Full Resolution Modes.
+The alternative Arming method **Arm using Switch** doesn’t use CH5 /to communicate the user's Arming request to the TX module. This means your Channel 5 will be free for other functions, like controlling gains on your stabilizer, or changing flight modes, or as a regular full proportional channel when using any of the Full Resolution packet rates and Modes. **Arm using Switch** is performed by user selected sources, e.g. physical or logical switches, anything EdgeTX offers as a source really. **Arm using Switch** works for all packet rates and switch modes but is especially useful for full res packet rates in combination with PWM receivers. No more “remapping CH5” required to use CH5 as a regular proportional control channel. **Arm using Switch** can be enabled in the EdgeTX Internal/External RF Model Setup menu by changing “Arm using” to “Switch”.
 
-!!! Note "Arming Mode Switch Requirement"
-    Arming Mode Switch **requires** EdgeTX version 2.11 or newer and ExpressLRS version 4.0 or newer. If you cannot find the "Arm using" option, that means you NEED to update your EdgeTX firmware.
