S 3 - 1 PRESET:INH S 3 - 1 PRESET:RSRV S3-1. PRESET INHIBIT (Initialization inhibited) Initialization of the back-up IC is not executed. Select this sub-menu to protect the values set by the user. S3-1. PRESET RESERVED (Initialization reserved) Initialization of the back-up IC is reserved. (Actual initialization is executed when the power is turned on next.) To reset to the original factory settings or to reset the backup IC, select this sub-menu and press the “MAIN ZONE ” key to turn off the power. CAUTION: Before setting to the PRESET RESERVED, write down the existing preset memory content of the tuner. (This is because setting to the PRESET RESERVED will cause the user memory content to be erased.)

Right after power is turned on, confirm that the voltage across the terminals of R1152 (SURROUND BACK Rch), R1154 (SURROUND Rch), R1150 (FRONT Rch), R1148 (CENTER), R1149 (FRONT Lch), R1153 (SURROUND Lch) and R1151 (SURROUND BACK Lch) are within the confines of 0.1 mV to 10 mV. 2. If measured voltage exceeds 10 mV, open (cut off) R1104 (SURROUND BACK Rch), R1106 (SURROUND Rch), R1102 (FRONT Rch), R1100 (CENTER), R1101 (FRONT Lch), R1105 (SURROUND Lch) and R1103 (SURROUND BACK Lch), and then reconfirm the voltage. Attention If the measured voltage exceeds 10 mV after repairing the power amplifier, check other parts again for any possible defect before cutting the resistor. 3. Confirm that the voltage is within the confines of 0.2 mV to 15 mV after 60 minutes. 0.1 mV 10 mV (DC) R1104 (SURROUND BACK Rch) R1106 (SURROUND Rch) R1102 (FRONT Rch) R1100 (CENTER) R1101 (FRONT Lch) R1105 (SURROUND Lch) R1103 (SURROUND BACK Lch) R1152 (SURROUND BACK Rch) R1154 (SURROUND Rch) R1150 (FRONT Rch) R1148 (CENTER) R1149 (FRONT Lch) R1153 (SURROUND Lch) R1151 (SURROUND BACK Lch) Open (cut off) Front side MAIN (1) P.C.B.
