Deterioration in the conductive
coating inside the case
The inside of the case is coated with a conductive material. If the
board undergoes repeated detaching/attaching, the coating on the
boss may deteriorate.
If the resistance value between the case center and the head of the
boss becomes 5Ω or more, the effect of conductive coating cannot
be expected. In such a case, replace the case.
Note : Consider about the natural environment carefully before through the old lithium battery away when you exchange to the new one.you exchange to the new one.

The wiring differs depending on the serial number (the location of
the red wire is opposite). The difference between before and after
the change is as follows.
Before change
Applicable serial numbers: ZL90100 ~ ZL90199
Applicable parts #******* WIRING 11p
There is no difference in the circuit board before or after the change.
As parts for servicing, only the newer wiring (01898989 WIRING
W11) is supplied.
The jack board supplied for servicing has the newer wiring.
The older wiring was installed only on the first production lot of one
hundred units (ZL90100 ~ ZL90199).
•If you replace the jack board wiring with the newer version
(01898989 WIRING W11) on a unit with a serial number
ZL90100 ~ ZL90199, make connections using the newer
method (figure 4).
•If you retain the existing jack board and replace only the main
board of a unit with a serial number ZL90100 ~ ZL90199, make
connections using the older method (figure 2).
•If you retain the existing main board and replace only the jack
board on a unit with a serial number ZL90100 ~ ZL90199, make
connections using the newer method (figure 4).
