Note:
Auto Re-tuning will only operate on FM band.
1. Tune to an RDS station using the automatic or manual tuning methods.
2. AF function is switched ON/OFF by pressing the AF/REG button (11).
When the AF symbol is shown on the display, AF function is switched on. If no AF data is received,
the AF symbol will flash.
How the AF function works?
In AF mode, the radio measures at regular intervals the signal strength at frequencies
that are mentioned in the list of Alternative Frequencies (AF’s) of the current station.
If an alternative frequency is found, it switches immediately to the new frequency if the
quality of the current station becomes suddenly very poor, or if its RDS data cannot be
received. The quality of a station is a function of signal level as well as multipath condition.
Note: In areas of severe multipath reception this may cause noise or the AF function to constantly
change. Should this occur then switch off the AF function. Try using the AF function later.
Regional
Press and hold the AF/REG button (11) for longer than 2 seconds (until the radio beeps.)
The current state of the REGIONAL Mode is indicated by a message “REG ON” or “REG
OFF”. Which is displayed for 4 seconds after the AF/REG button (11) is pressed.
To check whether an Alternative Frequency is a real Alternative for the current station,
the radio compares PI codes. (Programme Identity)
Regional Mode is ON: The PI codes must be exactly identical.
Regional Mode is OFF: The Region identification code in the PI code is ignored.
When regional mode is OFF, the radio may switch from a National Programme to a local
variant of that Programme, or from a local station in one area to a local station of an
other area. When Regional Mode is ON, the radio will only switch to an alternative that
broadcasts exactly the same programme. For best performance it is recommended
that the Regional function remains in the OFF, Function is REG OFF.
CT FUNCTION (CLOCK TIME)
This software incorporates a real time clock which is updated from the RDS signal.
When a station is tuned in the unit will decode the incoming clock data and after
approximately 2 minutes will display the correct time when the DSP button is pressed.
Press DSP button once-CT displayed; DSP button twice-Programme type; DSP button
three times-Frequency display.
After 5 seconds the display will revert to station name display.
Note:
Some stations do not transmit a PTY or CT information and therefore the clock
or programme type display may not be available.
