Alignment Preparation & Precautions

  A dummy load and inline wattmeter must be connected to the main antenna jack in all procedures

that call for transmission, except where specified otherwise. Correct alignment is not possible with an

antenna. After completing one step, read the following step to determine whether the same test

equipment will be required. If not, remove the test equipment (except dummy load and wattmeter, if

connected) before proceeding.
