Appendix A – Safety Precautions & Regulatory Standards compliance Appendix A – Safety Precautions & Regulatory Standards Compliance Safety Precautions IMPORTANT! FOR THE EFFICIENT AND SAFE OPERATION OF YOUR CDMA INTEGRATED MODEM READ THIS INFORMATION BEFORE USE. RF Safety General Your ModemModule is based on the CDMA standard for cellular technology. Your modem is actually a low power radio transmitter and receiver. It sends out and receives radio frequency energy.
Appendix A – Safety Precautions & Regulatory Standards compliance General Safety Driving Check the laws and the regulations regarding the use of cellular devices in the area where you have to drive as you always have to comply with them. When using your modem while driving, please: give full attention to driving, pull off the road and park before making or answering a call if driving conditions so require.
Appendix A – Safety Precautions & Regulatory Standards compliance Safety Standards THIS WIRELESS MODEMMODULE COMPLIES WITH ALL APPLICABLE RF SAFETY STANDARDS.
Appendix B – Sourcing Guide for Connectors/Peripherals Appendix B – Sourcing Guide for Connectors and Peripheral Devices CDMA Antenna The integrated modem antenna connector is a MMCX connector. The MMCX connector incorporates a 'Snap On' latching action in order to make the connection easier with an excellent RF performance. An additional advantage is its small physical size, which is 50% of the standard MCX connector.
