HOW TO
USE:
Paging is possible from other station by dialing the station number
assigned to this module. To prevent a calling tone from being
sounded through the paging speaker, the module is designed to
override paging output during a period of time that the calling tone
signal is transmitted. The length of time to mute the paging output
is adjustable between zero and three seconds. During paging,
background music (the input signal fed to E-11, X-11, L-11 or B-11
module) is muted.
