SOUND LEVEL ADJUSTMENTReceive E-12ch (PAL colour bar). Signal con- tent: 400Hz 100% Mod.Connect the probe of the meter (*) to (SI) con- nector.Select SUB-VOL in the service mode.Adjust the SUB-VOL data to make the meter indicate 10.8Vrms (at L-ch). Adjustment value : 11.2 Adjustment value :Receive E-12CH (PAL colour bar).Maximize the sound volume to verify that the sound is output from the speaker. Then, set the non-signal state.At this time, verify that the audio mute oper- ates.After checking the operation, set the sound volume to be the smallest.Receive E-69CH (PAL colour bar). (Set the receiving frequency at AFT OFF 855.25 MHz.)Connect the digital voltmeter to TP202 (in the main unit).Verify that it is turned counterclockwise to 0V and clockwise to 5V, and adjust T2300 to make the DC voltage of TP202 become 2.5 the range.
