When the device boots up (as well as after a reset), it uses the regular power mode - with slightly reduced transmitter power (at 14dBm) and lengthened interval (60 seconds) between transmissions.

Click the user button (centre button) to switch between regular power mode and boost power mode.

Under the boost power mode, the transmitter transmits at 20dBm and shortens the transmission interval to 20 seconds.
