General Glossary
Page Clear
If manual page entry (via the console DTMF/paging keypad) is in progress,
this function will abort the current key entry sequence and clear the paging
display without altering the existing page stack. If a page entry is not in
progress, pressing this key will delete all console page stacks. If a page
transmission is in progress, it will also immediately abort the page
transmission. This function should always be programmed if the console is to
be used for paging.
Page Safety
If this function is programmed, instant-call pages will not be transmitted until
this key is pressed, allowing the operator to review the selected instant-call
pages before sending them. If this key has not been programmed, pressing an
Instant Call page key will begin the page transmission immediately.
Page Send
This paging function will terminate any manual page entry in progress (as if a
PAGE ENTER key had been pressed), and begin transmitting the manual page
stack on the currently selected channel(s) in the order the pages were stacked
(entered). The page stack is retained and can be transmitted again (on different
channel(s), for example) by pressing this key again.
Page Stack
A set of one or more pages, ordered in a stack to be sent out in sequence.
Talk Time
Talk Time is the default amount of time after a page is finished that the
microphone and transmitter are keyed up for the purpose of allowing the
dispatcher to transmit an audio/voice message.

Comprises all backroom system elements such as racks and card cages.
Channel
Used to describe the point-to-point communication path within the Series
4000 system.
Clipping
Audible distortion that occurs when a signal’s level exceeds the limits of
the amplifier circuit. When the analog signal is a sine wave, clipping
results in a waveform with a “flat top.” Clipping can be reduced by
decreasing the input signal amplitude to the amplifier or by reducing the
gain of the amplifier.
