CAUTIONS WHEN SERVICING

The DX-MBO has no power supply circuit. Power should be supplied from (IX-80. (EX-BUM. (IX-81M using an ll-core
flat cable. During repair, connect DX-M80 to the CX-80, CX-BOM, CX-81M to supply the power.
When there is no [IX-80, (IX-80M, (IX-81M, supply the power in the manner below.

(When repairing without CX-SO, CX-80M, CX-81M)
1. Remove soldering from C2) and © terminals of T51 not to
flow DC through T51.

2. Connect the Multi-Power Supply(LPS-9088) in the manner below.

. FL501 does not light. as AC power for FLSOl is not supplied.

The voltages below are supplied to each CONlOl
