Compliance Statements

⚠ Warning!
Sensus devices are for professional installation only. They are to be serviced by professional personnel only. This product is NOT for consumer installation or servicing.

Warning!
Hazardous voltages are present: to reduce the risk of electric shock and danger to personal health, follow the instructions provided in the product manual.

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.
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 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
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

⚠ Attention!
Any modifications made to this device that are not approved by Sensus may void the authority granted to the user by the FCC to operate equipment.

⚠ Attention! ICES-003 Class B Notice–Avis NMB-003, Classed B This Class B digital apparatus complies with Canadian ICES-003.

⚠ Warning! When applicable, there is danger of explosion if batteries are mishandled or incorrectly replaced. On systems with replaceable batteries, replace only with the same manufacturer and type or equivalent type recommended per the instructions provided in the product manual. Do not disassemble batteries or attempt to recharge them outside the system. Do not dispose of batteries in fire. Dispose of batteries properly in accordance with the manufacturer’s instructions and local regulations.

Warning! For products with multiple power cords, all power cords must be disconnected to completely remove power from the system.

⚠ Warning! For products that use power cords, not all power cords have the same current ratings. Do not use the power cord provided with your equipment for any other use. Household extension cords do not have overload protection and are not meant for use with computer systems. Do not use household extension cords with your Sensus product.

⚠ Warning! Do not dispose in fire, mix with other battery types, charge above specified rate, connect improperly, or short circuit, which may result in overheating, explosion or leakage of cell contents.

⚠ Warning! This radio is intended for use in occupational/ controlled conditions, where users have full knowledge of their exposure and can exercise control over their exposure to meet FCC limits. This radio device is NOT authorized for general population, consumer or any other use.

⚠ Warning! Sensus products are designed to be connected only to a grounded main circuit outlet. Do not defeat the plug grounding pin and do not plug these products into a non-grounded main power circuit.

⚠ Attention! This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.

⚠ Attention! This radio transmitter, M420 Transceiver, has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.

DIPOLE 10dBd (12.15 dBi)
DIPOLE 18 dBd (20.15 dBi)

⚠ Attention! Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

⚠ Warning! ANTENNAS: An outdoor antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can come in contact with such power lines or circuits as death or serious injury can occur. Be sure the antenna ysstem is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electric Code (NEC) in the U.S.A. provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes and requirements for the grounding electrode. Antenna grounding shall be according to the National Electrical Code, ANSI/NFPA 70.

⚠ Warning! This product can expose you to chemicals including Di(2-ethylhexyl)phthalate (DEHP), which are known to the State of California to cause cancer or birth defects or other reproductive harm. For more information, visit www.P65Warnings.ca.gov.
