This simple, compact and low power transceiver is designed for embedding in user's portable or fixed equipment and suitable for various low power industrial telecontrol and telemetry applications requiring high performance and reliability. All high frequency circuits are enclosed inside a robust housing to provide superior resistance against shock and vibration. Using a TCXO as the reference oscillator circuit of the radio component ensures high frequency stability in the temperature range from -20 to +65 °C. The LMD-401 is the same size and pin-compatible with Circuit Design’s EN 300 220 compliant license-exempt transceiver model STD-302Z that has been widely used as a standard transceiver for remote control in industrial radio applications. Features  Programmable RF channel with 12.5 kHz channel space  10 mW, GFSK, 4800 bps  Low power operation 3 - 5.5 V, 46 mA/TX, 36 mA/RX  High receiver selectivity & blocking  Small size 50 x 30 x 9 mm  Excellent mechanical durability, high vibration & shock resistance  Wide operation range - 20 to +65 °C  FCC part 90 and ISED RSS-119 certified Applications  Industrial remote control  Telemetry  Remote monitoring / Security  Data acquisition/ SCADA OG_LMD-401_v10e Circuit Design, Inc. 4 OPERATION GUIDE SPECIFICATIONS LMD-401 All ratings at 25 +/-10 °C unless otherwise noted General characteristics Item Units MIN TYP MAX Remarks Applicable standard FCC Part 90.217, ISED RSS-119 Communication method Simplex, Half-duplex Emission class F1D Modulation type GFSK Operating frequency range MHz 458.000 462.500 Operation temperature range °C -20 65 No dew condensation Storage temperature range °C -30 75 No dew condensation Aging rate ppm -1 1 TX freq., RX Lo freq.

Shonan EMC Lab. 1-22-3 Megumigaoka, Hiratsuka-shi, Kanagawa-ken, 259-1220 JAPAN Telephone: +81 463 50 6400 Facsimile: +81 463 50 6401 2020/5/13 FCC ID: V9X-LMD401 To whom it may concern, We, UL Japan, Inc., hereby declare that UHF Narrow band multi channel transceiver, model : LMD-401 (FCC ID: V9X-LMD401) of Circuit Design Inc. is exempt from RF exposure SAR evaluation with RF Exposure Compliance requirements of the KDB 447498 D01 General RF Exposure Guidance. (It is necessary to comply of FCC section 2.1093 in reality, however, it is exempted by KDB 447498 D01.) KDB 447498D01 has the following exclusion for portable devices: The 1g and 10g SAR test exclusion thresholds for 100 MHz to 6 GHz a t test separation distances < 50 mm are determined by: [(measured maximum average output power(mW))/(Minimum separatio n distance(mm))]•[ √ f (GHz)] < 3.0 for 1g SAR and < 7.5 for 10g ext remity SAR where • f(GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is < 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. This device f = 0.4625 GHz, distance = 5mm (minimum separation distance: 5 mm was used in the calculation) and the measured maximum average output power was 10 mW So for this device: 10 mW [measured maximum average output power] / 5 mm [minimum separation distance] * ( √ 0.4625) = 1.4 *This is less than 3.0, so no SAR is required. Even taking into account the tolerance, this device can be satisfied with the limits. Thank you for your attention to this matter. Toyokazu Imamura Leader Consumer Technology Division
