Page 2: Safety Information
Fields with spectral components outside of this frequency range are generally incorrectly evaluated and tend to be underrated. Before using field strength measuring devices, you should thus be certain that all field components to be measured lie in the specified frequency range of the measuring device. 480836 V5.0 8/09... - Page 3 Mobile phone base station antenna radiation power density measurement Wireless communication applications (CW, TDMA, GSM, DECT) RF power measurement for transmitters Wireless LAN (Wi-Fi) detection, installation Spy camera, wireless bug finder Cellular/Cordless phone radiation safety level Microwave oven leakage detection Personal, environmental EMF safety 480836 V5.0 8/09...
