To delete all stations from the memory:
1) Turn the device off.
2) Press and hold [ ] (DELETE) until “dEL” and “ALL” flash on the display.
3) Quick press [ POWER/SLEEP ] to confirm and delete all stored stations.
Note: If the [ POWER/SLEEP ] button is not pressed for confirmation within 3
seconds, the delete function is exited automatically.
Using the Antenna Gain [ANT.GAIN] Switch
The distance and transmission power of radio stations are not all the same;
some received signals will therefore be strong whereas others are weak. To
improve the listening experience, sensitivity can be adjusted with the
[ANT. GAIN] switch. When listening to distant and weak signal stations, select
“DX” to increase sensitivity. When listening to strong (local) signals that seem
distorted, select “LOCAL” to avoid strong signal overload blocking.
AM Bandwidth Selection
Quick press [ AM BANDWIDTH -/+ ] repeatedly, or press the button and then
rotate the [ FINE TUNING ] knob, to select different bandwidths to enhance the
intelligibility of longwave, medium wave and shortwave signals. Selectable
bandwidths are:
LW/MW: 2.3, 3.5, 5.0 and 9.0kHz.
SW: 2.3, 3.5, 5.0 and 6.0kHz.
SSB: 0.5, 1.2, 2.3, 3.0 and 4.0kHz.
Wide bandwidth: Has better audio fidelity when receiving strong signals or
local stations.
Narrow bandwidth: Limits interference from adjacent strong signals and
background noise, thereby especially suitable for receiving weak and distant
stations.
