General Paging
To page to a zone select the desired zone/s by pressing the buttons 1-4 or by pressing the "All Call" button if all zones are
desired. Make sure the switch is in the centre position before selecting the zones. The selected zones' LED's will illuminate
to indicate they have been pressed. Move the "Push to talk" switch down to the "Page" position and speak into the
microphone. Release the PTT switch when finished. The selected zones' LED's will flash for a few seconds after paging has
finished. While these LED's are still flashing paging can be directed to these zones again by simply moving the PTT switch
back to the "Page" position.
If two paging consoles are connected to the system one console will be "Locked Out" when the other is in use.
Fig 6 illustrates an example of two consoles being used together. The first console is being used to page to zones 1 and 2.
The second console is inactive while the first console is in use.
NOTE : If both paging consoles are fitted then the ID must be set for each. See the Dip switch setting for details.
