3. OPERATION
POWER-ON
Following installation by qualified radio service personnel, turn on power to the encoder.
The first number shown in the display is the Zetron order number. The unit then displays its
software version number. Finally, the display clears and ends up showing one or more
hyphens which indicate successful power up completion and readiness for operation.
Any message such as “Err1” signifies an error condition (see “ Self-Test” in Section 6 for
more information on error codes). Make a note of the error code, then the unit should be
powered down and a call for repair made. A message of “SEtUP” indicates that no formats
have been programmed (see “Overview” in Section 5 for more information), or that all the
format programming has been deleted.
KEYPAD
A tactile, rugged 16-key conductive rubber keypad is built into the encoder. The keys are
labeled 0-9, *, #, A, B, C, and D. Three extra keys are labeled CLEAR, PAGE, and ENTER.
The 16 keys are used to key in the pager number. The PAGE key will send the paging
information, the ENTER key will temporarily store a pager number in stack memory, and the
CLEAR key will clear a partially entered number or message or stop a page in process and
return the display to hyphens.
CONFIGURATION
All the specific characteristics of pager formats, such as two-tone code plans or tone groups,
strapped digits and talk enable, as well as the general system behavior parameters, such as
talk time, Autopage enabling and binary polarity selection, are programmable from the
keypad.
Simple step-by-step menu prompts, yes/no questions, and requests for number values take you
through the programming of the encoder.
This programming feature allows a technician, who is knowledgeable about the paging
requirements, to make quick and easy changes whenever expansion or changing needs require
different paging encoder operation.
However, since the programming of the encoder is not part of typical encoder operation,
detailed information about programming can be found in Section 5.
