
NOTE: The LMD-400-R has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a commercial installation. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
· Reorient or relocate the receiving antenna.
· Keep water and moisture out of all antenna and radio fittings.
· Check all antenna connections – any imbalance in coax cable can cause
radio interference and receive / transmit problems.
Caution:
Changes or modifications not expressly approved by the party responsible for compliance could avoid the
user’s authority to operate the equipment.
Licensing of end-use products
LMD-400-R 458 MHz-462.5 MHz holds equipment authorization for transmitting equipment under Title 47 of the
Code of Federal Regulations Part 90. (FCC Identifier:
V9X-LMD400R)
This shall be the only guarantee of Circuit Design Inc for compliance with FCC regulations. Those who integrate
LMD-400-R 458 MHz-462.5 MHz in a system and operate the radio system in the United States are required to
apply for a user station license before the equipment can be operated. Application for the station license in Part
90 may be required to be submitted to a certified frequency coordinator for frequency coordination, then the FCC
licensing bureau issues a license for equipment users/stations. As local frequency management issues are
involved in licensing, Circuit Design Inc shall not be held liable for failure in obtaining the station license. Circuit
Design Inc recommends users to contact a certified frequency coordinator in the region in advance to confirm
whether or not a license can be granted.
