Please remove resistors R801-R805,
when replace to IX0450 (u-COM).
CAUTION:
For continued safety, replace safety critical components
only with manufacturer's recommended parts (refer to parts list).
indicates safety critical components. For continued protection
against risk of fire, replace only with same type and rating fuse(s).
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.
The DC voltage is an actual reading measured with a high imped-
ance type voltmeter as the AM/FM signal generator is specified to
the conditions as shown in the list below. The measurement value
may vary depending on the measuring instruments used or on the
