aNSONIC GAMMA NX 1 Programmable UHF Tranceiver 457-462 MHz Narrow
OverView
This NX1 version is based on our known European versions of NX1. It operates as GFSK narrowband transceiver in either simple Modem operation or in packet mode. All functions and technical data remain as in the standard NX1, except the selectable frequency ranges: those are in the 460MHz band to meet North American regulations. That means that the modules fall into the FCC Part90.217 mobile land regulation licensed band. Operation in US-FCC and Canada-IC is permitted due to according certification. Import to US/Canada is allowed if customers product refers to ‘contains FCC ID: 2A28Q-NX1 / IC ID: 27776-NX1 part’. For all further and detailed module operations please use the standard NX1-MP data sheets.
Warnings/Recommendations
- RF Exposure recommendations: The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not transmit simultaneously or operated in conjunction with any other antenna or transmitter within a device. End-users, installers and OEM integrators must be provided with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance
- 15.21 Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. Les changements ou modifications qui ne sont pas expressément approuvés par la partie responsable de la conformité peuvent annuler l’autorité de l’utilisateur à utiliser l’équipement.
