How to Operate Your ETW AM Radio This part tells you how your ETR@AM radio works. The Upper Knob The upper knob does these three things: It controls the volume. The VOL knob increases volume when rotated to the right. It lets you see what station you have. (When the radio is on, push the knob to display the station.) It tells you the time. (When the ignition is off, push the RECALL knob to display the time.) BAL (Balance) The BAL control behind the upper knob moves the sound between the left and right speakers. The Lower Knob Turn the lower knob to choose radio stations. Tone Levers Two levers control the tone of your radio. BASS --Slide this lever up to increase the bass response. TREBLE -Slide this lever up to increase the treble response. Adjust this lever to give a pleasing sound. If a station is weak and noisy, move TREBLE down to reduce the noise. 3-8
