Memory Preset Tuning
| The BTM function — how this function operates _
This function starts by scanning stations from
the lowest frequency of the currently tuned in
band. When a station is tuned in, it will be
stored in the memory on the preset number
button whose number is indicated on the
display window. If there is no preset number
indicated, it will be stored in the memory on the
preset number button 1 onward. It continues to
store the stations in the memory until all the
preset number buttons are occupied.
For example, if the FMi band was selected, it
will continue until the preset number button 6 on
the FMII! band is occupied. When all the preset
number buttons are occupied with the
memories before the highest receivable
frequency is scanned, the unit will start
scanning higher frequencies from where it was
left off. This is to check if there are any more
stations with clearer receptions than the ones
already stored in the memory.
Notes
¢There may be a situation where there are not enough
receivable stations due to the lack of stations in the
vicinity or weak broadcasting signals. In such cases,
the BTM operation may stop without all the preset
number buttons being stored with a memory.
elt you start the BTM operation from the FM! band, it
will continue to store stations in the memory on the
FMit and FMitt bands. Care must be taken if you wish
to keep the stored stations on the FMIl or FMIll
bands.
16
If a station with clearer reception ts found, the
unit will store it in the memory in place of a
station with an inferior reception.
Lastly, it rearranges all the stations in the order
of frequency from the lowest and stores them in
the memory. The whole operation is now
completed. The stations with clearer receptions
are stored in the memory on the preset number
buttons in the order of frequency.
eit you start the BTM operation from the FMI band,
will stop when all the memories on the FMill band are
occupied. it wilt not continue to the FMI band.
