i
Thank you for purchasing the Everyday Wireless Model TX-3B UHF FM Data Transceiver. Before
proceeding with the equipment installation, it is imperative that you read the following pages of notices and
precautions. In order to ensure your equipment installation complies with FCC specifications and fulfills all
warranty-related obligations, read comprehensively the IMPORTANT USER NOTICES and PRECAUTIONS
sections below.
IMPORTANT USER NOTICES
•FCC WARNING: This equipment generates or uses radio frequency energy. Changes or modifications
to this equipment may cause harmful interference unless the modifications are expressly approved in the
instruction manual. The user could lose the authority to operate this equipment if an unauthorized
change or modification is made.
•FCC RF Exposure Requirements: The antenna included with the Model TX-3bTransceiver must be
installed to provide a separation distance of at least 150 centimeters from all persons, must not be co-
located or operating in conjunction with any other antenna or transmitter, and must not exceed the
antenna gain specified in the Antenna Use description below. Failure to observe these restrictions will
result in exceeding the FCC RF exposure limits.
•Antenna Use: Various antennas are recommended, depending on customer requirements. A base station
antenna should be chosen based on licensing restrictions (ERP limitations). Suggested antennas,
depending on allowable ERP licensing, are as follows: Cushcraft CRX450B (7dBi, 450 – 470 MHz);
Antenex 4507 (9.14 dBi, 450 – 460 MHz); Antenex 4607 (9.14 dBi, 460 – 470 MHz); RFS 455-6 (12.14
dBi, 450 – 460 MHz); RFS 455-7 (12.14 dBi, 460 – 470 MHz). DO NOT use any other antenna with the
Model TX-3B Transceiver or modify the antenna / coaxial cabling without first consulting with
Everyday Wireless or an Everyday Wireless qualified service organization.
•Component Access: There are no service accessory parts inside the transceiver. Do not try to open the
transceiver without prior approval from Everyday Wireless. Opening the transceiver will void the
warranty.
•Service: Only qualified service personnel must install or repair equipment.
PRECAUTIONS
•Do not modify the transceiver for any reason.
•Do not expose the transceiver to long periods of direct sunlight, nor place it near heating appliances.
•The Model TX-3B UHF FM Transceiver transmits data in the 450-470 MHz frequency band, which is
regulated in the United States by the FCC. Because the FCC grants access to specific frequencies, and
can grant access by multiple users to the same frequency, system performance may be affected by the
presence of other nearby users of the frequency used by the owner of this transceiver.
•The United States Government is responsible for the operation, accuracy, and continued operation of the
Global Positioning System (GPS). Accuracy and position fixes (latitude, longitude and altitude) can be
affected by alterations made to the GPS satellites by the U. S. Government. Accuracy is subject to
change in accordance with the U. S. Department of Defense civil GPS user policy and Federal Radio-
navigation Plan. Positional accuracy and time to fix time can also be affected by poor view caused by
