NOTES

* As for this model, the tuner of the DSP type is used.

When you exchange it due to the tuner pack(BL101;880-

2091M) trouble, it is necessary to adjust for S-meter etc.

Special JIG is necessary for an accurate adjustment. The

procedure document for the exclusive use jig is appended

to it.

* This system controller IC M30876FJBGP(IC402) of Main

PWB does not have program. Please use special JIG at

the time of IC ex-change to write the memory.

* This DSP IC SAF7730HV/N317(IC301) of Main PWB is

exposed die soldering pad type. It cannot remove in an

ordinary soldering iron.

Please use special removal JIG at the time of IC ex-

change

* The word mark and logos are owned by the

Bluetooth SIG, Inc. and any use of suchmarks by

CLARION CO.,LTD. is under license.

* 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.
