ADJUSTMENT
Item FM noise convergence Procedure <MAIN> 1. An antenna input is fixed to a main channel using a jig(Control panel unit). 2. Set an antenna input to main channel. 3. Input the FM 98.1/55dBu(1kHz, 22.5kHz MOD)signal. This state is standard output(=0dB). 4. Adjust VR161 so that the output level becomes -25dB, when set the SSG output is -20dB. <SUB> 1. An antenna input is fixed to a sub channel using a jig(Control panel unit). 2. Set an antenna input to sub channel. 3. Input the FM 98.1/55dBu(1kHz, 22.5kHz MOD)signal. This state is standard output(=0dB). 4. Adjust VR160 so that the output level becomes -20dB, when set the SSG output is -20dB. 1. 2. 3. 4. An antenna input is fixed to a main channel using a jig(Control panel unit). Set an antenna input to main channel. Input the 98.1MHz/55dBu(1kHz, 22.5kHz MOD)signal. Adjust VR162 so that the input level becomes 32dB.
