enough to display the RDS information.
Press the AF button and ʻAFʼwill appear at the top of the display.
If the current station (or stations) being scanned has a good
RDS signal strength button ʻAFʼwill display in bold. If a poor
RDS signal strength or no RDS is found for the tuned station the
ʻAFʼwill 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
ʻREG ONʼand ʻREGʼwill display at the top of the display. Tuning

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 ʻUSB PLAYʼsign will
appear on the LCD. Remove the USB stick and the unit will
revert to CD or Radio mode.
Important Note About Antenna Cabling.
75Ωcoaxial antenna cable will provide better shielding than the
supplied 300ΩFM 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 tunerʼs 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.
