E. Station Identification Cards
After filling out the station identification
card, insert in onto the display, followed
by the plastic cover, as shown in the
diagram to the right.
A. Accessing the Programming Mode
In order to program, you must first connect a C.O. line or analog PABX/KSU station port in parallel to the attendant
port (pins 25 and 50 - V/S and S/V). A telephone or test set must also be connected to the same pair. The
following programming must be done from this Touch Tone phone.
B. Programming the LM-24M
To begin programming, pick up the attendant's phone (pins 25 and 50 - V/S and S/V). Enter
on which character is accepted by your phone system. The display will flash twice and remain off, to indicate the
programming mode has been entered. The programming mode is exited when a valid or invalid program is
entered, or when the phone is returned to the on-hook position.
To disable display for one line only.............................
To disable displays for multiple lines...........................
To set a ring delay for one line only............................
To set a ring delay for for multiple lines.......................
Note: The LM-24D will flash the corresponding ring delay and then remain on. Programming is exited at this point
and the unit returns to the run mode. If an invalid program is entered, the LM-24D will sound an audible alert tone
and the current programming sequence will be canceled. On first time power up, all lines are enabled with a ring
delay of one. Once programmed, the ring delays are set from non-volatile memory.
C. Programming Examples
1. Pick up the attendant's phone (pins 25 and 50 - V/S and S/V) and enter
2. Complete the following examples...
Programming the LM-24M to....

The LM-24M scanner is shipped with all lines enabled. To disable (or not light) any of the 24 lines, some
programming is necessary as explained in section B above.
