BGM/MOH
The PBX provides Background Music and Music on Hold. Up to 6 external music sources (e.g., user-supplied
radio) can be connected to the PBX.
CAUTION
The MOH port is an SELV port and should only be connected to an approved SELV device, via a Line
Isolation Unit with a Telecommunications Compliance Label.
Notice
•
Wiring should be done carefully to prevent undue force being exerted on the plug. Otherwise, sound
may only be heard intermittently.
•
When the PBX and external music source are not connected to the same earth, hum noise may be
induced into Background Music and Music on Hold.
Pager
A paging device (user-supplied) can be connected to the PBX.
CAUTION
The Pager port is an SELV port and should only be connected to an approved SELV device, via a Line
Isolation Unit with a Telecommunications Compliance Label.
