A: CAUTION
•Before disassembling or reassembling parts, al-
ways disconnect the battery ground cable from bat-
tery. When replacing the audio, control module and
other parts provided with memory functions, record
the memory contents before disconnecting the bat-
tery ground cable. Otherwise, the memory is
cleared.
•Reassemble the parts in the reverse order of dis-
assembly procedure unless otherwise indicated.
•Adjust parts to the given specifications.
•Connect the connectors securely during reas-
sembly.
•After reassembly, make sure functional parts op-
erate smoothly.
