numbered 1 to 6 holds up to five RDS program types. The RDS
program types can be accessed in two stages.

Press PTY and then press any of the buttons numbered 1 to 6
twice will yield two separate codes per button.

To access the other three codes per button, press PTY then PTY
again, and then press any of the buttons numbered 1 to 6 from
one to three times.

After pressing the buttons the tuner will scan and lock into the
RDS code type station. If no RDS code type station exists the
tuner will display PTY NONE (no program type).

To find the next station of the designated program type press
one the TUNE buttons.

To turn off the PTY function, press the PTY button twice in
succession. The PTY will disappear from the display.

13. AF/REG

AF( Alternative Frequency):

Using this button allows the user

to know if a searched station has an RDS signal strength strong
enough to display the RDS information.

Press the AF button and

will appear at the top of the display.

If the current station (or stations) being scanned has a good
RDS signal strength button

will display in bold. If a poor

RDS signal strength or no RDS is found for the tuned station the

will flash. In this situation press the AF/REG button to turn

off the flashing display.

REG (Regional mode):

To activate this function, AF must be on

(either bold or flashing in the display). Press this button for three
seconds to switch to regional mode. The main display will show

REG ON

and

REG

will display at the top of the display. Tuning

can now commence to find stations with weaker signals. Press
the AF/REG button for 3 seconds to turn off this function. The
display will show

REG OFF

momentarily

Pressing this button allows the tuner to lock into strong signal
strength stations only.

14. USB Slot:

Connect a USB stick to this socket and the

USB PLAY

sign will

appear on the LCD. Remove the USB stick and the unit will
revert to CD or Radio mode.

Important Note About Antenna Cabling.

coaxial antenna cable will provide better shielding than the

supplied 300

FM cable, which will reduce noise and

interference on the tuner. A better antenna, oriented toward the
signal source (i.e. broadcast towers) will also improve signal
reception. Connecting the GND connection to the earth on the
PA amplifier will also reduce electrostatic noise, especially for
AM reception.

About RDS Functions - Radio Data System.

Allows a tuner

s LCD screen to display text information being

transmitted by FM analogue radio stations. RDS technology is
becoming more prevalent in Australia. RDS Codes: PTY –
Program Type (ie Station format or music genre); PS - Station
Name or ID; DATE or CLOCK

TIME; TEXT - Song Title, Artist,

Station slogan, traffic updates etc. If the FM radio station in
question has not activated and/or is not broadcasting RDS data,
then the RDS feature will show nothing, no scrolling text, time,
station name etc.
