User Manual
The HS-DWAM80/D2DIA module is a wireless audio transceiver module. The module holds the
radio transceiver IC, the DARR80 digital audio baseband processor and associated components
and circuitry .
Basic Features:
--Low latency ( configurable from 10……18ms )
--In-room or multi-room usage (point to multi-point is also supported )
--Bi-directional data channel
--Automatic frequency allocation
--Automatically controlled transmitter / receiver antenna spatial diversity minimizes fading and
multipath effects.
Pairing function :
all units in the same wireless audio network are provided with a 16bit network ID,shielding the
network from neighbor audio networks.
The HS-DWAM80/D2DIA is used for both the transmitter and receiver .The module is configured
either through the I2C interface ,through the EEPROM or through the optional microcontroller.
Label requirement:
if the FCC / IC identification number is not visible when the module is installed inside the host device, then
the outside of the device into which the module is installed must also display a label referring to the enclosed
module.This exterior label can use wording such as the following:
"Contains FCC ID:XCO-HSMD2DIA80 and IC:7756A- HSMD2DIA80."
Any similar wording that expresses the same meaning may be used.
REMINDING
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
Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
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.
MPE Reminding
1. The installed antennas must not be located in a manner that allows exposure of the general
population at a distance of less than 20cm.
2. Mount the antennas in a manner that prevents any personnel from entering the area within
20cm from the central position of the antenna.
