Note the following:

It is recommended to use a Sound Pressure Level (SPL) meter to manually calibrate output levels. An SPL meter is a device that measures the relative loudness of the speakers to ensure accurate output level calibration. SPL meters are available at Radio Shack (catalog no. 33-2050).

Output levels should be calibrated from the primary listening position, placing the SPL meter at the approximate location of the listener’s head during listening.

Output levels for speakers that are not included in the speaker setup cannot be adjusted during the internal noise test. These output levels can be adjusted during the external noise test, but there is no need to do so.
