Mounting the HPA module
To mount the new HPA, repeat the above procedure in reverse:
1. Fit the threaded studs on the back of the HPA into the holes in the
mounting bracket on the antenna. Apply a small amount of Loctite 243 onto
each of the four threaded studs before mounting the finger nuts on the
threaded studs. Fasten the nuts with 1.2 Nm torque.
2. Reconnect the plugs. Make sure the plugs are fitted properly. You should
hear a click when the plug is fully inserted.
3. Gently lift the cable holders and fit the cables in the holders.
