Logic Table 1) Destination
The destination in AMP does not mean the sales regions but specific models. The following are the models. When reset is released, it is checked only once.
Model name KAC-PS811D/X811D KAC-PS521/X521 KAC-PS621/X621 KAC-PS541/X541 MODEL1 (29pin) Low Low High High MODEL2 (30pin) Low High Low High

2) AMP ID
AMP ID is checked only ohce at the time reset is released or when the microcomputer is released from the low consumption mode. When set to AMP ID 8/9 no remote control is possible.

CAUTION : For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts list). Indicates safety critical components. To reduce the risk of electric shock, leakagecurrent or resistance measurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer. · DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual instruments or/and units.

CAUTION : For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts list). Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer. · DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual instruments or/and units.
