FCC Regulations
QDM023-BG95-M1 complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class
B digital device, under 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 by 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.
FCC RF Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. To comply with FCC RF exposure compliance
requirements, this grant applies to only Mobile Configurations. The antennas
used for the transmitter must be installed to provide a separation distance of
at least 20cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.
Electrical interface for the meter to the communication module
The communication module is connected to the meter through a USB Type-A Male connector that provides main power supply voltages, USB signals. The direction of signals is toward a communication module based on DTE – DCE notation where the meter is defined as DTE (data terminal equipment) and the communication module is defined as (data communication equipment). Table 3 specifies the function of each interface signal, and photo 2.1 is the actual application scenario.
