HOW TO CHANGE THE ADDRESS
SWITCH
When connecting an CD changer and MD changer by Ce-
NET,no more than 2 units can be connected.When both of
them are CD,the address switch needs to be reset so that
the address switch number is not the same for each.
How to change the address switch
Switch the address by using a plastic stick with a sharp
tip or equivalent.
Caution
・
The unit may not operate when both CD changers are
set to the same address switch number.
・
Never change the address switch during operation.Doing
sp can cause malfunction or breakdown.Do not change
the address switch forcibly,because this may also cause
malfunction.
・
The Ce-NET cable wiring must be less than
20m(65.62ft)in length.
・
Be sure that the CD changer numbers are not the same.
・
Do not use the address switch numbers "3" and "4" for
the MD changer.
