4. on the cpu reset board are 4 jumper positions (con-1 - con4).
each jumper position provides a different frequency range and configuration. from the list below, select the desired frequency range and configuration, and move the jumper shunt to the corresponding con.
con 1 : 10 meter only (28.000 - 29.699 mhz)

*in expanded mode, either the frequency or channel can be displayed on the lcd. to switch between freqency display and channel display, press the func button and then press the call button (do not hold down for 3 seconds).
*on the channel display, the small number (0 - 9) to the right of the band letter is the 1 khz frequency display. example: if the frequency is 27.405, then the channel display will indicate 40 e5. "40" being the channel, "e" being the band, and "5" being the 1 khz position of 27.405.
