Replacing Q22 (FET TX final)
1. Place Q22 in its location, upside down as shown in figure 1. Make sure the location of each pin is correct. The bevelled edge is located between pin 1 and 2. (See the figure below) Replace the heat conductor sheet (G11-2664-x4) when replacing Q22. TX-RX UNIT A/3 Foil side

2. The bottom surface of Q22 must be firmly contacted to the TX-RX PCB. Solder each pin onto the top of the metal posts. Make sure the solder is between the pin and the metal post (Refer to figure 2). 2. Q22���表��须���-��PCB紧���� ��个管������顶端��起�����须��管�� ����������2�
Note:
� Make sure you are properly grounded while soldering the Q22. � Avoid adding excess solder to the metal post. � Make sure the bottom surface of Q22 is firmly contacted to the TX-RX PCB. � The metal posts for the pins are also soldered to the PCB. So, when you solder the Q22 pins to the metal posts, keep the soldering time as short as possible so that the posts are not moved.
