OPERATING INSTRUCTIONS

5Loudness Control (BAND/ LOUD)

When listening to music at low volume levels, this feature will boost the bass and treble ranges to compensate for the characteristics of human hearing. Press and hold the BAND/ LOUD button (5) to activate this feature as indicated by a beep tone and “LOUD ON” appearing on the display panel. (“LOU” remains on the display.) Pressing and holding the button again will sound a beep tone and display “LOUD OFF”. “LOU” will disappear.

7FM Mono Select (MON)

During FM radio operation, the MON button (7) is used to select monaural or stereo reception of the broadcast signal. Under normal reception conditions, the unit should be left in the stereo mode (indicated by “STEREO” when tuned to an FM stereo signal). If the signal is too noisy for comfortable listening, press the MON button; the “STEREO” indication will disappear from the display panel and “MONO” will appear. To return to stereo reception mode, press the button again.

9Local Button (LOC)

During radio operation, received signals are usually in stereo mode as indicated by the “ST” icon; however, when the signals are weak or intermittent, you can activate the Local (LOC) mode by pressing the LOC button (9)(“LOC” appears on the display). This mode favors access to local stations whose signals are much stronger; thereby improving radio reception. Press the LOC button again to terminate Local receive mode (“LOC” disappears from the display panel).

Press the up or down TUNE/ TRACK buttons momentarily to tune two frequency steps at a time.If no further tuning is performed after five seconds, “AUTO” will appear momentarily on the display, and tuning will revert to the original tuning mode.

8Auto-Store/Pre-Set Scan (AS/PS or AMS)

Press the AS/PS or AMS button (8) momentarily to scan the 6 stations in the pre- set memory for all FM bands. The unit will stop at each pre-set station for 10 seconds. Press AS/PS or AMS again to stop scanning and select the current frequency. Press the AS/PS or AMS button for more than 2 seconds to activate the Auto-Store Tuning feature. The radio will automatically scan the band in use and enter strong stations into the pre-set memory positions for that band. Auto-Store will erase any stored stations.

10Audio Mute (MUT)

Press the MUT button (10) to silence the volume from the system. “MUTE” will appear on the display panel. Press MUT again (or activate another function) to return the volume level to the setting that was in use before the Mute function was activated.
