	then press evenly until the receptacle tabs lock into place.

	switcher on page B-2.

Installing a firmware update

The IC that contains the firmware for the matrix switcher also contains the memory in which audio levels are saved. When you replace the IC, these settings will be lost. You may want to record the audio levels before you replace the IC.
