�ADJUSTMENT
Item Noise convergence Clock accuracy Procedure 1. Input a 98.1MHz/55dB(1kHz,30% MOD)signal.(0dB=1.4V) 2. Adjust the output to �18±3dB by VR102 when the SSG output is set �20dBμ. 1. Turn off and on the ACC switch,while holding CD EJECT button and POWER button.Repeat it twice slowly. 2. Set a universal timer to TP201,adjust TC201 so that a reading of the meter is 0±0.1 sec/day.
