SDBM420V00Base Station Transceiver

M420 TRANSCEIVER QUICK GUIDE AQG-10120-01 The M420 transceiver is a full duplex FlexNet® transceiver intended for installation into a Sensus FlexNet® M420B or M420D Base Station. By providing dual M420 transceivers, a single base station can simultaneously support communications for both AMI meter reading systems and high value applications such as DA, DR, HAN, and lighting control while transmitting and receiving in a 200 kHz band of spectrum. This bandwidth enables more dedicated channels and higher network traffic capacit y.

Sensus devices are for professional installation only. They are to be servied by pro- fessional personnel only. This product is NOT for consumer installation or servicing. RF Radiation Hazard! In order to satisfy the FCC RF exposure limit for transmitting devices, a separation distance of the following must be maintained: • 366 cm (12 ft.) while operating the Sensus M420 transceiver with the M400G2 PA and a 12.15 dBi antenna • 371 cm (12.17 ft.) while operating the Sensus M420 transceiver with a M420PA and a 12.15 dBi antenna • 918 cm (30.11 ft.) or more while operating the Sensus M420 transceiver with the M400G2 PA and a 20.15 dBi antenna • 931 cm (30.54 ft.) or more while operating the Sensus M420 transceiver with the M420 PA and a 20.15 dBi antenna To ensure compliance, operations at closer than this distance are not recommended. This minimum safe distance is required between personnel and this antenna of this device. Note: CFR 47 Part 101 limits the radiated power to 1,000W in the 941.0 MHz to 941.5 MHz frequency band. Use of a 20.15 dBi antenna may require the use of an inline RF attenuator. Professional installation required. RF Radiation Hazard! In order to satisfy the ISED RF exposure limit for transmitting devices, a separation distance of the following must be maintained: • 544 cm (17.85 ft.) while operating the Sensus M420 transceiver with the M400G2 PA and a 12.15 dBi antenna • 552 cm (18.11 ft.) while operating the Sensus M420 transceiver with a M420PA and a 12.15 dBi antenna • 1367 cm (44.85 ft.) or more while operating the Sensus M420 transceiver with the M400G2 PA and a 20.15 dBi antenna • 1386 cm (45.47 ft.) or more while operating the Sensus M420 transceiver with the M420 PA and a 20.15 dBi antenna To ensure compliance, operations at closer than this distance are not recommended. This minimum safe distance is required between personnel and this antenna of this device. Afin de satisfaire la limite d’exposition RF ISED pour les appareils de transmission, une distance de séparation de éléments suivants doit être maintenue: • 544 cm (17,85 ft.) ou plus pendant le fonctionnement du Sensus appareil (M420 émetteur-récepteur avec le M400G2 PA et un antenne de 12,15 dBi) • 552 cm (18,11 ft.) ou plus pendant le fonctionnement du Sensus appareil (M420 émetteur-récepteur avec le M420 PA et un antenne de 12,15 dBi) • 1367 cm (44,85 ft.) ou plus pendant le fonctionnement du Sensus appareil (M420 émetteur-récepteur avec le M400G2 PA et un antenne de 20,15 dBi) • 1386 cm (45,47 ft.) ou plus pendant le fonctionnement du Sensus appareil (M420 émetteur-récepteur avec le M420 PA et un antenne de 20,15 dBi) Pour assurer la conformité, un fonctionnement à distance inférieure à celle est pas recommandée. Cette distance minimale de sécurité est nécessaire entre le personnel et l’antenne de cet appareil. Note: SRSP-505 limits the radiated power to 250W, 600W, or 2,500W depending on the use case in the 941.0MHz to 941.5MHz frequency band and in the 952.0MHz to 953.0MHz frequency band. SRSP-509 limits the radiated power to 2,500W in the 930.0MHz to 931.0MHz frequency band and in the 940.0MHz to 941.0MHz frequency band. Use of a 20.15 dBi antenna may require the use of an inline RF attenuator. Warning! The antenna used for this transmitter must not be co-located in conjunction with any other antenna or transmitter. Attention! For Class B - Unintentional Radiators: This equipment 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 residential installa- tion. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful in- terference to radio communications. However, there is no guarantee that interfer- ence 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 encour- aged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna • Increase the separation between the equipment and receiver • Connect the equipment into an outlet on a circuit different form that to which the receiver is connected • Consult the dealer or an experienced radio/TV technician for help Warning! Hazardous voltages are present: to reduce the risk of electric shock and danger to personal health, follo…
