information.
Press the AF button and ʻAFʼ will appear at the top of the display. If the
current station (or stations) being scanned has a good RDS signal strength
button ʻAFʼ will display in bold. If a poor RDS signal strength or no RDS is
found for the tuned station the ʻAFʼ 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

stations only.
14. USB Slot:
Connect a USB stick to this socket and the ʻUSB PLAYʼ 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.
75Ω coaxial antenna cable will provide better shielding than the supplied 300Ω
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 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.
