Brief introduction
HYM740 UHF RFID reader uses R2000 chip, which complies with EPC C1G2
protocol, its working frequency is 902~928MHz，with LBT function. It supports dense
reader working mode（DRM）。With standard 7dBi antenna，the reading distance can
reach 24 meters, maximum identifying speed can reach 400/S; with simple power
supply and interface circuit, a high-performance RFID system can be established. It is
suitable for logistics, apparel, medical industry, and complex assets management, etc.

Changes or modifications made to the equipment not expressly approved by Winnix may void the
FCC / IC authorization to operate this equipment.
The use of the transceiver module is authorized in mobile or fixed host devices taking into account
the conditions listed below
:• OEM Integrator must ensure that the end user manual may not contain any information about
the way to install or remove the module from the final product.
• Depending on the final host device additional authorization requirements for the nontransmitter
functions of the transmitter module may be required (i.e., Verification, or Declaration of
Conformity) The OEM integrator is responsible for ensuring that a er the module is installed and
operational the host continues to be compliant with the Part 15B unintentional radiator
requirements.
• The information on the label and in the user manual is required to be incorporated in the user
manual of the final host. see 47 CFR15 requirements for more details (e.g. 15.19 / 15.21 / 15.101 /
15.105 / RSSGEN / ICES)
• Additional label with the words ‘Contains FCC ID: RVZHYM740’ shall be applied and visible
from the outside of the host product.

• The module must be installed and used in strict accordance with the manufacturer’s instructions
as described in the user documenta on that comes with the module
.• The end user manual for the final host product operating with this transmitter must include
operatng instructions to satisfy RF exposure compliance requirements. e.g
Radiofrequency radiation exposure Information:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance of 25 cm
between the radiator and your body.This transmitter must not be colocated or operating in
conjunction with any other antenna or transmitter
.• When the final host product operating with this transmitter deviate from above, installation of
this module into specific final hosts may require the submission of a Class II permissive change
application containing data pertinent to RF Exposure, spurious emissions, ERP/EIRP, and
host/module authen ca on, or new application if appropriate
Feel free to contact us if additional guidance is required.

RF EXPOSURE
This Module complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment under the following condition: The device shall be used in such way that at least a
distance of 25 centimeters is maintained between the antennas and the body of the user and nearby
persons.
Antenna Information
The HY740 includes an external antenna port.
Here are some design guidelines to help ensure antenna performance:
. Never place the ground plane or route copper traces directly underneath the antenna portion of
the module.
. Never place the antenna close to metallic objects.
. In the overall design, ensure that wiring and other components are not placed near the antenna.
. Do not place the antenna in a metallic or metallized plastic enclosure.
. Do not place the antenna in a metallic or metallized plastic enclosure.
. Keep plastic enclosures 1cm or more from the antenna in any direction.
