Introduction
The DM870 Core-2 module is a single-board networked media player module, based on BridgeCo’s
DM870 media processor, and enables fast product developments with ethernet, WiFi and USB
connectivity. The module connects to standard legacy components in various audio, video/LCD and
control formats. It runs from a single 5V power supply and creates all the necessary voltages on the
module. A stabilized 3.3V power is provided to the main board, to allow for further system cost
reduction.

FEDERAL COMMUNICATIONS COMMISSION INTERFERENCE STATEMENT
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.
CAUTION:
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
RF exposure warning ·
This equipment must be installed and operated in accordance with provided instructions
and the antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 20 cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter. End-users and installers must be
provide with antenna installation instructions and transmitter operating conditions for
satisfying RF exposure compliance.
This device 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.
Canada Warning
"Industry Canada regulatory information 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. ""The user is
cautioned that this device should be used only as specified within this manual to meet RF
exposure requirements. Use of this device in a manner inconsistent with this manual could
lead to excessive RF exposure conditions."
