Tuning Step Settings
Change MW (AM) tuning step - 9K/10K
In Europe and most other parts of the world, the MW (AM) tuning step is 9 kHz. In Northern and Latin America, the MW (AM) tuning step is 10 kHz.
MW (AM) tuning step can be set whether the radio is ON or OFF. Press and hold the Menu button until a beep sounds and the Menu icon appears. Press the 9k/10k button; the display will show "MW" and flash "9 (kHz)" or "10 (kHz)" for the Northern American version. Use the tuning UP/Down button to select 9 or 10, then press ENTER to complete the setting.
Change FM tuning step - STEP
FM tuning step varies in different countries. FM tuning step can be set whether the radio is ON or OFF. Press and hold the Menu button until a beep sounds and the Menu icon appears. Press the Step button (5); the display will show "FM" and flash "100 (kHz)". Use the tuning UP/Down button to cycle through 100/200/50 (kHz), then press ENTER to complete the FM tuning step setting.
Set the AGC (Auto Gain Control)
In AM band (MW and SW), if the volume level changes too rapidly during listening, you can delay the response by setting the AGC IF (intermediate frequency) gain.
- AGC is for AM (MW/SW) only.
- The AGC function sets the IF (intermediate frequency) gain; it has 3 selections: 50db/auto/30db.
- "Auto" selection is the default AGC level which has a balanced gain for reception, recommended to set on auto for general purpose.
- Select 50 db to have a higher IF gain than "auto"; it can amplify weak signals 10dB more than auto. The background noise will be enlarged, but it is easy to make the signal saturate under a stronger signal. In addition, the soft mute may not be active because of more background noise.
- Choose 30db to have a lower IF gain than "auto"; if you prefer to receive only stronger signals, reducing the IF gain is able to reject weak signals and background noise.
Auto Clock Time Adjustment by RDS-CT
You can enable auto clock time adjustment by the RDS (Radio Data System) CT function. Clock time can be automatically adjusted by FM RDS stations.
Note: RDS function is mostly available in European countries and part of Northern America area.
To enable or disable the RDS-CT function, whether the radio is ON or OFF, press and hold the Menu button until a beep sounds and the Menu icon appears. Press the CT button (7); the display will show "OFF" (disable CT function). Use the tuning UP/Down button to cycle through ON and Off, then press ENTER to complete the CT enable or disable setting.
Note:
