all of the individual pager codes have been transmitted, regardless of what position the fixed
stack number had in the keypad stack.
The maximum number of pager capcodes that can be placed in a fixed stack is limited by the
“stacks” memory available. As a general thumb rule, each stack can hold ten pages. The exact
capacity of a fixed stack can be calculated using the worksheet found at the end of Section 7.
The last pager capcode position can be used to call the stack number of another fixed stack
(this is taken care of by the programmer when the fixed stacks are set up). Any number of
fixed stacks can be strung together this way, up to the limits of the encoder's available
database memory.
The rules governing the programming of fixed stacks are somewhat different than the ones for
keypad stacks. These are covered in more detail in “Custom Stack-Page Format (Fixed
Stack)” in Section 5.
Talk
Many formats allow a voice message to follow the paging transmission. The duration of this
talk interval is set under programming and is the same for all formats. Several of the formats
are programmed with the Talk time enabled or disabled when the format is set up; other
formats enable or disable Talk time based on the function code number entered when the page
is actually made.
If a Talk interval is activated, the transmitter is kept ON after the page is completed and the
desk microphone activated. The display prompts the operator with the message “tALH”. The
voice message can be given during the Talk interval and then the transmitter is turned off.
Longer voice messages can be sent in the normal manner by pressing the push-to-talk (PTT)
on the desk microphone. Shorter voice messages can be terminated before the Talk time
expires by pressing the CLEAR key. When Talk time is not used, the transmitter is turned off
immediately after sending the paging information.
Some formats use an additional transmission to mute the pagers. If a Talk time is enabled for
such a page, the desk microphone is turned off after the Talk interval and the additional
transmission is sent to mute the pagers before turning off the transmitter. If a short voice
message is terminated with the CLEAR key, the pagers will be left unmuted and an additional
page may be necessary to mute them.
Paging Sequence
Once the pager number has been entered, the PAGE key may be pressed. If no message is
expected, the encoder will immediately start the paging sequence. If a message format and/or
function have been selected, the encoder responds to the PAGE key with a message prompt.
After the message has been entered, another depression of the PAGE key starts the paging
sequence. Once the paging sequence starts, the encoder:
1. Validates pager numbers and messages. This verifies that all entered digits are
recognized by the format. An invalid pager number is shown by a blinking display. If a
