What’s this?
• A station can deliver a message to a mass of people just by lifting your handset and dialing a code.
• This feature is helpful when it is required to call few people for meeting.
• This feature is of great use in factories, offices, etc. where it is not feasible to provide a station to every
individual. In such cases, if you need to call somebody you can just make an announcement naming him to
come and see you or call you.
• This can also be used for mass communication.
How to make connection for the PAS port?
The Vision supports one audio output port for personal address/public address.
• If personal address is to be made, a speaker of 4Ù/8Ù can be directly connected to the PAS port.
• Please take care to keep the jumper J6 on the card in A-B position.
• If public address is to be made, an external amplifier with matching speaker should be connected to the PAS
port. The jumper J6 should be in B-C position.
• Connect a good quality amplifier and matching speaker to the audio port marked PAS as shown in the figure
given below:
• Keep the distance between the PBX and the amplifier to reduce noise pick up.
• Use shielded cable for connecting the system with the amplifier.
