 (1)
 Make sure that the lights on the face of the transceiver are not on.

 (2)
 On the related Radio Management Panel (RMP), put the ON/OFF selector switch to ON. Make sure that the RMP shows the last frequency and function used.

 (3)
 Push the related HF1 (HF2) pushbutton switch and monitor that the integrated green LED comes on. Additionally the white SEL indicator light comes on.

 (4)
 With the dual selector knob set a station frequency in the STBY/CRS window.

 (5)
 Push the transfer pushbutton switch (left-right arrow) between the two display windows to start the set frequency. This sets the antenna coupler to its 'home' position.

 NOTE : You must not transmit on this set frequency. If you activate
____ the transceiver to transmit, the 'home' position of the coupler is discarded.
 NOTE : The HF antenna coupler must not be removed before it is set to
____
 its 'home' position.

 NOTE : If you activated the transmitter by mistake, do the procedure
____
 described above again.

 (6) On the related RMP, set the ON/OFF selector switch to OFF.
