Operating Instructions
1. Power On/Off
Press and hold the OFF/ON button to power the radio on or off.
2. Band Selection
Press the BAND+ or BAND- buttons to cycle through the available frequency bands: FM, AM (MW, SW), and SSB (LSB, USB).
3. Tuning
Rotate the large TUNE/BFO/ATS knob to adjust the frequency. A short press on this knob may switch between fine tuning and coarse tuning modes, or activate ATS (Automatic Tuning System) depending on the current mode.
4. Volume Adjustment
Use the VOL+ and VOL- buttons to increase or decrease the audio volume.
5. Bandwidth (BW) Selection
Press the BW button to cycle through different audio bandwidth filters (e.g., 0.5, 1, 1.2, 2.2, 3, and 4 KHz). Selecting the appropriate bandwidth can improve signal clarity and reduce interference.
6. Mode Selection (SSB)
When in SSB mode, use the MODE button to switch between LSB (Lower Sideband) and USB (Upper Sideband).
7. Step Adjustment
The STEP button allows you to change the tuning step size, which can be useful for precise tuning or quickly scanning frequencies.
