Appendix A – Safety Precautions and 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 SocketModem 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 and 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 must comply with these laws and regulations. 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 and Regulatory Standards Compliance General Safety Standards THIS WIRELESS SOCKETMODEM COMPLIES WITH ALL APPLICABLE RF SAFETY STANDARDS.
Appendix A – Safety Precautions and Regulatory Standards Compliance Regulatory Standards Compliance CDMA compliance The SocketModem is in compliance with reference regulations: TBR 19, TBR 20, TBR 31, TBR 32. CE Label The Wireless SocketModem is CE compliant, which implies that the modem is in conformity with the European Community directives and it bears the CE label. Multi-Tech Systems, Inc.
Appendix B – Sources for Peripheral Devices Appendix B – Sources for 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. This type of connector is suitable for the standard ranges of flexible and semi-rigid cables.
