What is the BTM (Best Tuning Memory) function?
BTM is a function that selects the radio stations with the
strongest signals and automatically sets them to preset
station numbers. The BTM function starts tuning in
stations from the lowest frequency on the band (FM or
AM). When a station is found, the unit assigns the
frequency to the currently selected preset station number.
When preset numbers are not displayed, the unit assigns
frequencies starting with preset station 1.
Even after the unit has assigned frequencies to all the
preset station numbers, the unit continues tuning. If
stronger signals are found, the unit replaces the current
preset stations with the stronger frequencies. Finally, the
unit sorts the stations in ascending order by frequency.
