Reference Frequency
Set the transceiver to CH 2 (band center) via the “CH” box on the “Alignment” window previously.
To adjustment, click the left mouse button on the “RF Frequency” box, then press the [ENTER] key to open the
Use the [] or [] arrow keys so that the frequency counter displays the band center frequency (±100 Hz) for the version being aligned.

Transmitter Output Power
Set the transceiver to CH 2 (band center).
To adjustment, click the left mouse button on the “RF Power {High}” or “RF Power {Low}” box, then press the [ENTER] key to open the
Use the [] or [] arrow keys so that the power meter reading is 5.0 W (± 0.1 W) (for “RF Power High”) or 1.0 W (± 0.1 W) (for “RF Power Low”). Confirm that the current consumption is 2.3 A or lower (for “RF Power High”) or 1.0 A or lower (for “RF Power Low”).

To adjustment, click the left mouse button on the “MAX Deviation” box, then press the [ENTER] key to open the
Use the [] or [] arrow keys so that the deviation meter reading is ±4.2 kHz (±0.1 kHz) (for 25 kHz steps) or ±2.1 kHz (±0.1 kHz) (for 12.5 kHz steps) deviation.
