RDS (Radio Data System)

The unit features an integrated RDS decoder compatible with RDS data transmissions. This system allows automatic switching to the station with the best reception when moving over long distances (AF switching). It also receives traffic announcements (TA) or program type (PTY) information from RDS stations, regardless of the current mode.

Press and hold the VOL/SEL knob to enter the settings menu. Briefly press VOL/SEL to select an item, then rotate the knob to choose the desired setting: AF (ON/OFF) → TA (ON/OFF) → TA VOL → REG (ON/OFF) → EON (ON/OFF) → SEL PTY.

• Alternative Frequency (AF): When AF mode is selected, the radio scans for alternative frequencies. If a new AF signal is stronger than the current station, it briefly switches to that frequency. (Flashing AF indicates a search for a stronger RDS station). Segment OFF means AF switching is off; Segment ON means it's active and RDS info is received; Flashing AF means AF is active but RDS info is not yet received.
• Traffic Alarm (TA): In TA standby mode, traffic announcements are received with priority. If TA mode is turned off, traffic announcements are cancelled.
• TA SEEK: If a tuned station lacks TP information for 5 seconds, the radio seeks the next station with TP.
• TA ALARM: Disables automatic retuning; outputs only an alarm beep.
• TA VOL: Adjusts the TA volume level (default 25).
• Region ON/OFF (REG): Selects local (REG ON) or national (REG OFF) broadcast reception.
• Program Type Selection (PTY): Allows searching for specific program types (e.g., NEWS, SPORTS, MUSIC).
