Operation
USING THE L70’S AM/FM RADIO
CHOOSING THE FM MUTE / MODE
The front-panel FM MUTE/Mode key is a dual-purpose control. First, it “toggles” the L70 between stereo mute and unmuted mono reception (assuming that a multiplex-stereo station of sufficient strength is tuned). FM Mute eliminates noise from “empty” FM frequencies but also mutes very weak or distant stations. Toggling off the FM Mute will result in reduced noise if the FM station signal level is less than the FM Stereo threshold (since mono FM is inherently less noise-prone), though at the sacrifice of the stereo effect.
NOTE
Toggling between FM Mute on or off also defeats the L70’s FM muting circuit. If you wish to listen to a particularly weak or distant broadcast, toggle off the FM Mute and tune it manually.
ABOUT RDS
The Radio Data System (RDS) permits compatible FM receivers to display text determined by the broadcaster. The L70 supports two RDS modes, station-name (PS mode) and radio-text (RT mode). However, not every FM station incorporates RDS in its broadcast signal; in most areas you will find from one to several RDS-enabled stations, but it is by no means impossible that your favourite stations will not be broadcasting RDS data.
VIEWING RDS TEXT
When an RDS-enabled FM broadcast is tuned, after a brief delay the “RDS” symbol will light in the L70’s front-panel readout and the readout’s character section will show its station-name (PS) text: “ROCK101,” for example. Press the front-panel DISPLAY key to toggle the readout between this and the station’s radio- text (RT) readout, if any, which might scroll song- or artist-name, or any other text of the station’s choosing.
ABOUT USER NAMES
You can assign an eight character “User Name” to each radio preset, which will show in the front-panel readout whenever that preset is recalled.
ENTERING USER NAMES
For example, to name a radio preset “NEWS”: recall the desired radio preset, and then press the front-
panel DISPLAY key for about four seconds; the readout shows a blinking bar. Use the PRESET 
keys
to select the first character of the name (“N” from the alphabetic list; press either TUNE 
key to select the character and move to the next position. Repeat this process for each character in sequence; press the MEMORY key again to store the User Name and exit the text-entry mode.
