If you think the volume level is too low to listen to FM broadcasts on your car radio, use a standard tip screwdriver

20、or other instrument to turn the switch clockwise. If you think the volume level is too high or there is distortion, turn the switch counterclockwise. The higher the setting number, the higher the volume level. Pre-emphasis selector Normally, set the pre-emphasis selector to “2”. (The initial setting

21、 is “2”.) If you feel the treble is insufficient, switch the selector to “3” with the tip of a pen or other pointed instrument to boost the treble slightly. If you feel the treble is too strong and the sound becomes distorted, either return the selector to “2” or switch it to “1”. ICs marked by * are MOS type. Be careful in handling them because they are very liable to be damaged by electrostatic induction. 16 1234 1234 F E D C B A CD-V61FM/E Fig. 1Fig. 2 Fig. 3 Fig. 4 Fig. 5 2 ! 0 98 # 3 $% 1 4 5 6 7 2 ! 0 98 # 3 $ 1 4 5 6 7 & 2 ! 0 98 # 3 1 4 5 6 7 1 ( * ) 1
