Maximum adjustment range of the active radio channel frequency is ± 1 MHz counting from the
factory set centre frequency. Because of possible deviations in each country and/or region
concerning the authorised use of the frequency spectrum local authorities may limit this
adjustment range. SATELLINE-3AS radio modem can be supplied with the adjustment range
divided into two bands (Band 1
Band 1Band 1
Band 1 and Band 2
Band 2Band 2
Band 2), and this feature can be utilised in case it is
required to limit the arbitrary adjustment of the active radio channel accidentally to a forbidden
value. The centre frequency and the frequency band limiting values are factory set and the user
cannot change them. The active channel is selected by entering a numerical value.
