1. o LUMOO002AF Rev B Version 6 3 31 b Spread Spectrum Wireless Data Transceiver User Manual 3 FREQUENCY ZONE Frequency Zone The idea of frequency zoning is to divide the available band 902MHz to 928 MHz into smaller bands in this case 16 smaller bands each consisting of 7 Frequency channels These 16 Zones are stored in a Word which is made up of 16 bits numbered 0 15 These bits when displayed LSB to MSB directly represent the zones that the radio will operate on from lowest frequency to highest A value of 1 in the bit sequence will instruct the radio to operate within the represented band Likewise a 0 value will instruct the radio to bypass the represented band This feature should only be used with the standard hop table Binary Zone Number LSB First Beginning Freq MHz Ending Freq MHz Number Of Channels 902 2464 903 6288 0 2 S547 906854 L3 p 3e 34m p 7 908 6976 910 0800 S sisi E 7 6 Ss 885 7 7 T o ss 7 RENE RENNES RENE I NN REN ANN 916 7616 918 1440 ser 37 4 Ss 59 7 i12 T aoo ses amp 4 7 L8 snm 3888 7 924 8256 926 2080 826 4564 arsa 7 Frequency Zones are activated through the Setup menu To enable zoning from the main Setup menu of the radio NNT NT NP RE SIE RE NT NT NN NN 1 Select Menu 3 Edit Radio Transmission Characteristics 2 Select Option
