specific memory pages (pages 01-24). For example, if memory page 11 already contains frequencies that
were previously stored with other storage methods (manual storage, auto scan storage, ATS) then these
will be replaced when performing AP ATS during the 09:00 - 12:59 time interval.
● It is possible to perform AP ATS for FM and LW, but this will only replace the frequencies that are already
stored in memory pages 01-24 and not create time-specific memories. To automatically tune and store FM
and LW memories in pages 01-24, please use Auto Tuning Storage (ATS) as indicated on page 16.
● If there is a time period change during AP ATS, the device will stop scanning and delete all frequencies
stored in the previous time period, after which it automatically re-scans and stores the frequencies into the
new time period.
AP Manual Storage
If AP ATS missed certain frequencies (e.g. due to interference), then it is possible to add these manually:
1) Quick press the [ VF/VM ] (SCAN) button . The frequency flashes twice and enters VF mode.
2) Select the band and frequency.
3) Quick press the [ M ] button . “ PRESET ” flashes in the top right corner of the display.
4) Press and hold the [ PAGE ] (AP) button. “ ” and “ PRESET ” flash on the display.
5) Quick press the [ M ] button to confirm.
If the threshold levels for the signal strength and signal-to-noise ratio are set high, the capture sensitivity is
low, which means that broadcasts with weak signals will be missed. If the threshold levels for the signal
strength and signal-to-noise ratio are set low, the capture sensitivity is high, which will result in radio noise
mistakenly being regarded as radio signals and stored into memory.
Optimizing ATS Frequency Storage Results in Auto Paging (AP) Mode
The factors influencing the results of ATS in AP mode are the same as described for ATS on page 17. By
adjusting the capture threshold levels of the signal strength and signal-to-noise ratio, it is possible to try and
improve the ATS results in AP mode for MW (AM) and SW under different signal receiving conditions.
