Station/Trunk Switch - Switch to STATION when
connecting the "control line" to a C.O. line or an analog
PABX/KSU station.  Switch to TRUNK when connecting
the "control line" to a dedicated phone or unused (loop
start) trunk input.

Neon/LED Switch - Switch to
NEON when using standard
90-125V message waiting
phones or Viking Model LM-1
on standard phones.

Connect the Yellow and Black to the positive of the talk
battery, normally earth ground (see 

Important below).

After wiring J1, the polarity may be tested using a
volt meter.  An easier method is to use a Viking
model  LM-24D display in conjunction with the
MLC-24’s built in diagnostics as follows:

1.  Be sure that J2 is disconnected and that J1 is 
     connected and wired.
2.  Make sure the BK and Y of the “COM” RJ-14 
     are connected to the earth ground (positive side 
     of the battery).
3.  Connect a Viking LM-24D display to the COM 
     jack.
4.  Set the dip switches as 
     shown below.
5.  Momentarily press the
     reset switch.  If any LED’s
     remain lit, reverse tip and
     ring (going to J1) for that 
     line, and retest.

Important:  The Yellow and Black of the RJ-14
jack, “COM”, MUST be connected to the positive of
the talk battery for proper reference.  This is
normally earth ground on most C.O. lines or
analog PABX/KSU stations.

Note:  This application requires that the correct
polarity (tip=positive, ring=negative) be observed
on J1 for proper operation.

Most 48 volt C.O. line or analog PABX/KSU
stations require no station rewiring as the 90 to
125 volt signal is superimposed on the existing tip
and ring.  The lamp controller is compatible with
standard 90 to 125 volt message waiting lamp
phones as well as Viking model L M - 1 retrofit
message waiting lamp kit installed on modular
analog station sets.
