LM-1A
Message Waiting LED
Lamp Retrofit Kit
October 14, 2008
The message waiting lamp retrofit kit is compatible with
any telephone system with standard DC message waiting voltages ranging from 90VDC to 120 VDC.
The LM-1A is fully modular for quick plug-in installation
by non-telephone personnel. The unit’s LED will blink at
a steady rate when the message waiting voltage is
detected.
The LM-1A will also flash when the phone rings, helping
to reduce noise in quiet areas by providing a convenient visual indication for ringing or message
waiting. Notes: 1. The LM-1A is not designed to recognize stutter dial tone from any ana-
log telephone company phone line or PABX. 2. The LM-1A is not compatible with any
AT&T phone system.

between foam and individually boxed. All equipment should be wrapped to avoid packing material lodging in or stick-
ing to the equipment. Include ALL parts of the equipment. C.O.D. or freight collect shipments cannot be accepted. Ship

and troubleshooting, a Return Authorization (R.A.) number will be issued. This number is valid for fourteen (14) calen-
dar days from the date of issue.
3. After obtaining the R.A. number, return the approved equipment to your distributor, referencing the R.A. number. Your
