MARS SmartRadio Installation Guide
To ensure proper connection and resistance to water intrusion a
waterproof butt splice is required to connect the SmartTransmitter to the
meter register. The recommended type of connector is a Scotchlok™
connector. This type of connector is ideal because it provides a good
mechanical connection of the wires and a waterproofing gel that inhibits
water ingress.
This device is designed to be installed at or above ground level outside of
buildings and meter pits. Professional installation by factory trained
personnel is required for proper use and reliable communication.

Installation Steps
1. Refer to the table above for wiring color codes.
2. While holding the Scotchlok™ connector with the button facing
down, insert un-stripped wires fully into connector.
3. Once seated, use a crimper and firmly squeeze the connector until
you hear a snap and gel seeps out of the end of the connector.
4. Repeat steps 1-3 for the other two pairs of wires and test to ensure
the SmartTransmitter is transmitting properly.

Information to the User
FCC Class B:
“NOTE: 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 from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.”
Warning: Changes or modifications to this device not expressly approved by
MARS Company could void the user’s authority to operate the equipment.
RF Exposure
In accordance with FCC requirements of human exposure to radiofrequency
fields, the radiating element shall be installed such that a minimum separation
distance of 20cm is maintained between it and the user or general population.
