NOTES
*
The tuner of this unit is BUS-TUNER type. When the
tuner pack(BL101) is exchanged, it is necessary to ad-
just for S-meter etc. with special JIG.
*
Individual data of each unit is recorded in EEPROM
IC(IC401). When EEPROM IC is replaced, it is neces-
sary to write the data.
*
DSP IC(IC301) is fixed with solder. Special JIG is nec-
essary for removing it.
*
This product includes technology owned by Microsoft
Corporation and cannot be used or distributed without a
license from MSLGP.
*
We cannot supply PWB with component parts in prin-
ciple. When a circuit on PWB has failure, please repair it
by component parts base. Parts which are not mentioned
in service manual are not supplied.
*
Specifications and design are subject to change without
notice for further improvement.
