    TR489 totally contains three different frequency Bands which are user selectable. Only one frequency band can be active at the time, which means that all user configurations are targeting at the selected band. Selection of active frequency band can be done with Satel configuration manager or using SL commands.

    The power level limit is defined separately for each sub-band. The maximum power limit for each sub-band is pre-programmed into the SATEL-TR489. The user can choose from 10, 20, 50, 100, 200 and 500 mW ERP* output power for frequency variant 856…876 MHz. No matter what power level the user has chosen the maximum allowed power level of the chosen sub-band cannot be exceeded.
