 ## rfswitch.send()
-Transmit value ising radio module.
+Transmit data using the radio module.
 
 #### Syntax
 `rfswitch.send(protocol_id, pulse_length, repeat, pin, value, length)`
 
 #### Parameters
 - `protocol_id` positive integer value, from 1-6
-- `pulse_length` length of one pulse in microseconds, usually from 100 till 650
-- `repeat` repeat value, usually from 1 till 5. This is synchronous task.
-Setting the repeat count to a large value will cause problems.
-The recommended limit is about 1-4, if you need more,
+- `pulse_length` length of one pulse in microseconds, usually from 100 to 650
+- `repeat` repeat value, usually from 1 to 5. This is a synchronous task. Setting the repeat count to a large value will cause problems.
+The recommended limit is about 1-4. If you need more,
 then call it asynchronously a few more times (e.g. using [node.task.post](../modules/node/#nodetaskpost))
-- `pin` IO index of pin, example 6 is for GPIO12 [see more](../modules/gpio/)
+- `pin` I/O index of pin, example 6 is for GPIO12, see [details](../modules/gpio/)
 - `value` positive integer value, this is the primary data which will be sent
 - `length` bit length of value, if value length is 3 bytes, then length is 24
