User Manual
The HS-DWAM82IA module is the wireless audio transceiver module. The module holds the
radio transceiver IC, the DARR82 digital audio baseband processor and associated components
and circuitry .
The HS-DWAM82IA platform can host many different applications ,requiring different external
components ,as a frame of reference ,for a simple stereo uni-directional audio link ,need to
external components are required.
Basic Features:
--Low latency ( configurable from <20ms )
--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-DWAM82IA 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.
REMINDING
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:
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.
—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.
To satisfy FCC RF exposure requirements, a separation distance of 20 cm or more should be
maintained between the antenna of this device and persons during device operation.
To ensure compliance, operations at closer than this distance is not recommended.
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.
This radio transmitter 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.
Antenna type: PCB antenna
Max gain: 1dBi
Antenna impedance: 50ohm
USERS MANUAL OF THE END PRODUCT:
In the users manual of the end product, the end user has to be informed to keep at least 20cm
separation with the antenna while this end product is installed and operated. The end user has
to be informed that the FCC radio-frequency exposure guidelines for an uncontrolled
environment can be satisfied. The end user has to also be informed that any changes or
modifications not expressly approved by the manufacturer could void the user's authority to
operate this equipment. If the size of the end product is smaller than 8x10cm, then additional
FCC part 15.19 statement is required to be available in the users manual: This device
complies with Part 15 of 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.
LABEL OF THE END PRODUCT:
The final end product must be labeled in a visible area with the following " Contains FCC ID:
XCO-HSMDWAM82IA and 7756A- HSMDWAM82IA".
FCC part 15.19 statement has to also be available on the label: This device complies with
Part 15 of 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.
If the size of the end product is larger than 8x10cm, then the following
Le présent émetteur radio a été approuvé par Industrie Canada pour fonctionner avec
les types d'antenne énumérés ci-dessous et ayant un gain admissible maximal et
l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans
cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement
interdits pour l'exploitation de l'émetteur.
Gain de l'antenne: antenne PCB
Gain max:1dBi
Impédance d 'antenne: 50ohm
