-# Set Transmit Power
+# set Transmit Power
 
 Make the ``radio`` signal of the @boardname@ stronger or weaker.
-It can be as weak as `0` and as strong as `7`.
+
+```sig
+radio.setTransmitPower(7);
+```
+
+The signal can be as weak as `0` and as strong as `7`. Default is ``6``.
 
 The scientific name for the strength of the ``radio`` signal is
 **dBm**, or **decibel-milliwatts**. A signal strength of `0`
 can be measured as -30 dBm, and a strength of `7` can be
 measured as +4 dBm.
 
-```sig
-radio.setTransmitPower(7);
-```
-
-### Range
+## Range
 
 If your @boardname@ is sending with a strength of `7`, and you are in
 an open area without many other computers around, the @boardname@ signal
 can reach as far as 70 meters (about 230 feet).
 
-### Parameters
+## Parameters
 
-* ``power`` is a [number](/reference/types/number) between ``0`` and ``7`` that
-means how strong the signal is.
+* ``power`` is a [number](/types/number) between ``0`` and ``7`` that means how strong the signal is.
 
-### Simulator
+## Simulator
 
 This function only works on the @boardname@, not in browsers.
 
-### Example
+## Example
 
 This program makes the ``radio`` send at full strength.
