ANTENNAS
A 1/4 wave antenna with a gain of less than 2.1dBi suitable for 457Mhz operation should be used with the
TEL2RADIO457 Radio module to ensure correct and reliable operation.
Notice: Use the antenna recommended as other antennas may invalidate compliance with the
regulatory standards.
Regulatory compliance information
WARNING: This module needs to have a License to comply with FCC Rules, please contact the IMC
Group for further information.
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.
Caution:
Any changes or modifications not expressly approved by the party responsible for product compliance could
void the user's authority to operate the equipment.
Caution Exposure to radio frequency radiation:
To comply with FCC RF exposure compliance requirements, a separation distance of at least 20 cm must be
maintained between the antenna of this device and all persons. This device must not be co-located or
operating in conjunction with any other antenna or transmitter.
Labeling:
The IMC Group Ltd
transmitter/Receiver module TEL2RADIO457 labeled as below.
FCC ID:
The proposed FCC ID label format is to be placed on the module. If FCC ID is not visible when the module is
installed into the system, the label should be placed on the outside of final host system "Contains FCC ID:
N20TEL2RADIO456
".
IC ID:
The proposed IC ID label format is to be placed on the module. If IC ID is not visible when the module is
installed into the system, "Contains IC: 10310A-T2RADIO456" shall be placed on the outside of final host
system.
Cautions
As the radio module communicates using electronic radio waves, there are cases where transmission will be
temporarily cut off due to the surrounding environment and method of usage. The manufacturer is exempt from
all responsibility relating to resulting harm to personnel or equipment and other secondary damage.
Do not use the equipment within the vicinity of devices that may malfunction as a result of electronic radio
waves from the radio module.
The manufacturer is exempt from all responsibility relating to secondary damage resulting from the operation,
performance and reliability of equipment connected to the radio module.
Communication performance will be affected by the surrounding environment, so communication tests should
be carried out before actual use.
User Guide – TEL2RADIO457
Ensure that the power supply for the radio module is within the specified rating. Short circuits and reverse
connections may result in overheating and damage and must be avoided at all costs.
Ensure that the power supply has been switched off before attempting any wiring work.
The case is connected to the GND terminal of the internal circuit, so do not make contact between the '+' side
of the power supply terminal and the case.
Do not use this equipment in vehicles with the windows closed, in locations where it is subject to direct
sunlight, or in locations with extremely high humidity.
The radio module is neither waterproof nor splash proof. Ensure that it is not splashed with soot or water. Do
not use the equipment if water or other foreign matter has entered the case.
Warnings
Do not take a part or modify the equipment.
Do not remove the product label (the label attached to the upper surface of the module.) Using a module from
which the label has been removed is prohibited.
This device complies with part 15 of the FCC Rules. Operation is subject to
the condition that this device does not cause harmful interference.
