long as pager number inputs are followed by an ENTER key they will be moved to memory
until the memory is full. At that point, no further depressions of the ENTER key will be
accepted. Press the PAGE key to send the calls consecutively in the opposite order of entry,
i.e. last in, first out.
Keypad stacks are temporary in nature, and once the stack has been transmitted, the encoder
clears the memory used, leaving only the last page made in the display. This means that,
unlike a page to an individual pager, an entire keypad stack cannot be retransmitted simply by
pressing the PAGE key (only the last pager capcode would be transmitted). To send the stack
page again, the entire stack would need to be entered into memory again. Pressing the
CLEAR key at any time in the keypad stack entry process causes all of the capcodes in the
memory stack to be lost; therefore entry of these pager numbers should be done with care.
Digital and tone formats should not be intermixed in a keypad stack. Calls allowing a data
message will not be accepted because the stack sequence would be stopped to receive a
message from the operator. Calls requiring an additional pager muting transmission are not
accepted because different formats may require different muting transmissions.
Custom Stacks (Fixed Stack Pages)
Some end-users may have a need to perform predefined stack pages with some regularity and
will want to be able to do so in a hurry whenever the need arises. The keypad stack feature
does not really serve the needs of these users because of the time required to enter more than
a few pager capcodes. The Model 15P can also be programmed with fixed stack pages that are
held in the encoder's non-volatile memory.
The Custom Stack feature is assigned to a leading digit just like one of the other paging
formats. Each of the fixed stacks is assigned an identifying number (like a pager capcode) up
to four digits long. In order to transmit one of the fixed stacks, the operator enters the leading
digit for Custom Stack paging followed by the identifying number for the stack required, and
then presses the PAGE key. The encoder displays each pager capcode in the stack as it is
transmitted. The pages are sent in the same order they were entered into the database during
programming (first-in/first-out). An Alert tone and/or Talk time to be used with the fixed
stack is assigned when the stack is programmed. These replace any Alert tones or talk times
assigned to individual pagers in the stack. The encoder takes care of these when all of the
pages are finished.
Some users, out of concern for not only speed but also operator training, may require that
fixed stacks can be sent with only a single key press. This can be accomplished by entering an
asterisk (*) for the stack number when programming the stack. For each leading digit that the
Custom Stack format is assigned to, the Model 15P will recognize one unnumbered stack.
When the operator enters just the leading digit and presses the Page key, the encoder checks
to see if there is an unnumbered stack and, if there is, sends it.
A fixed stack can be entered into a keypad stack along with other individual pager capcodes,
however, only one fixed stack can be included, and the fixed stack pages will not be sent until
