Set it to a frequency that is not used by an FM radiobroadcast station in your area. If there is interference, use astandard tip screwdriver or other instrument to turn theswitch clockwise or counterclockwise to select anotherfrequency. Modulator level rotary switch You can adjust volume level. At the time of purchase, theswitch is set to 4. If you think the volume level is too low tolisten to FM broadcasts on your car radio, use a standard tipscrewdriver or other instrument to turn the switchclockwise. If you think the volume level is too high or thereis distortion, turn the switch counterclockwise. The higherthe setting number, the higher the volume level. Pre-emphasis selector Normally, set the pre-emphasis selector to “2”. (The initialsetting 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 boostthe treble slightly. If you feel the treble is too strong and the sound becomesdistorted, 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 veryliable to be damaged by electrostatic induction.1612341234FEDCBACD-V61FM/EFig. 1Fig. 2Fig. 3Fig. 4Fig. 52!098#3$%145672!098#3$14567&2!098#3145671(*)1
