MICROPHONE PAGING AND ORDER OF PRIORITY

1.A microphone connected to the AM-821 can be used for recording and direct paging. Placing the microphone switch in the ON position enables you to make the microphone paging when the power is being fed to the AM-821. The built-in AGC circuit releases you from work to adjust the sound volume frequency.

2.The AM-821 is designed to allow the microphone paging to have the highest priority, overriding the background music and tape playback. Several seconds after the microphone paging is restored. When no microphone paging is being made, the pre-recorded announcement takes precedence of the background music.

Caution : Be sure to place the microphone switch in the OFF position after the microphone paging has been finished.
