10 When the {{html}}<span style="border-radius:4px;font-size:100%;font-weight:bold;background-color:#007bff;" class="badge bg-info">OK</span>{{/html}} button is pressed, the transceiver will enter transmission mode and output a tonal carrier.
11 The output power of the tonal carrier is the current transmitter power level **(TX POWER)** set before entering calibration mode.

13 By adjusting the **{{html}}<span style="font-size:100%;font-weight:bold; background-color: #28a745;" class="badge bg-dark">RF</span>{{/html}}** encoder, achieve equality between the **ACTUAL** output power (measured by the external power meter) and the pre-set **TX POWER** value.
14 When the {{html}}<span style="border-radius:4px;font-size:100%;font-weight:bold;background-color:#007bff;" class="badge bg-info">GEN</span>{{/html}} button is pressed again, or when exiting the transmitter operational settings window, the current calibration is saved to NVMEM memory and the device returns to receive mode.
