Regulatory Statement for FCC
The LMD-401 complies with the FCC Part 90.
Labelling:
The LMD-401 is labeled as below.
FCC ID: V9X-LMD401

Exposure to radio frequency radiation
This device complies with FCC radiation exposure limits set forth for an uncontrolled environment and
meets the FCC radio frequency (RF) Exposure Guidelines as this equipment has very low power levels of RF
energy.
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:
The LMD-401 is only authorized for FCC Part 90 and the host product manufacturer is responsible for compliance
to any other FCC rules that apply to the host product.
The final host product will need to be reassessed with the LMD-401 installed for compliance to FCC Part 15
Subpart B on host manufacturer’s responsibility, if applicable.
Changes or modifications not expressly approved by the party responsible for compliance could void the
user’s authority to operate the device.
This device must not be co-located or operated in conjunction with any other antenna or transmitter.
