To Whom It May Concern,

Reference: EUM3004 Submission (FCC ID "OOX-EUM3004") – LMS4000 900 MHz Radio Network

User's Guide Changes

Accompanying this submission is the

LMS4000 900 MHz Radio Network User's Guide

(W/R document

no. APCD-LM043-8.0), which is specifically for the CCU3000, EUM3000, (previously certified under FCC

ID "OOX-LMS3000") and EUM3003 (previously certified under FCC ID "OOX-EUM3003").

This user's guide is being updated to include reference to the EUM3004. The EUM3004 is a functionally

identical replacement for, and interoperable with, the EUM3000 and EUM3003, using the same software,

operating at the same frequencies, using the same RF encoding, and transmitting with the same power.

There are no key differences, from the user's perspective. The changes are internal only.

This leads to the following substantive changes in the User's Guide:

•

Changes to Regulatory Notices and Warnings to include the EUM3004.

We will be happy to provide a copy of the updated user's guide when it becomes available, if desired.

Yours truly,

Lawrence Gordon,

Senior Technical Design Lead,
