20.2 REPLACING BATTERY
MF3XXX-J9CATXX series have two batteries inside the card as follows.
Lithium battery; for main battery
(
replaceable
)
Rechargeable battery; for auxiliary battery
(
not replaceable
)
For main battery replacement, perform the following procedure. Performing any other procedures will lose the
data recorded in the IC card.
(
1
)
Have on hand a new main battery that has the same model number as or is equivalent currently installed one.
(
2
)
Insert the IC card into the system and apply power to the IC card so that the auxiliary battery will be charged.
(
more than 5 minutes
)
(
3
)
While pressing the main battery holder cam release levers inward, slowly withdraw the main battery holder.
(
4
)
With the new main battery set in the battery holder, insert it completely into the IC card.
(
5
)
If the battery holder is incorrectly oriented, it will not smoothly fit into its position or the IC card will bulge.
If such a situation is encountered, properly reorient the battery and battery holder and try again.
(
6
)
Insert the battery holder until it clicks into position.
<NOTICE>
Main battery replacement must be completed quickly
(
recommended time is within 10 minutes
)
.
If too much time is taken, the recorded data may be lost.
The built-in auxiliary battery cannot be replaced.
21. CONNECTOR
The number of card insertion and removal are as follows.
Office environment 10000 times min. at speed of 10 cycles/min.
Harsh environment 5000 times min. at speed of 10 cycles/min.
22. CARD WEIGHT
about 35g
23. UL CLASS OF MAIN CARD PARTS
(
1
)
MAIN FRAME UL94V-0
(
2
)
PCB UL94V-0
(
3
)
PLASTIC PART OF CONNECTOR UL94V-0
24. THE BATTERY VOLTAGE DETECT SIGNALS
(
BVD1,2
)
BVD1
BVD2
H
H
Battery operational

Battery and data integrity is not kept
Note10. The battery voltage detect signals indicate the present state of the battery.
They do not guarantee the data retention.
Comment
25.CONCERNING THE SECURITY OF DATA
There is always the possibility that a soft-error (this malfunction is not permanent hence it is called soft and
the data can be restored by rewriting) may occur with semiconductor products.
When keeping the important data within an IC card, remember to give due consideration to safety when
making your circuit designs, with appropriate measures such as
(1) Keeping multiple copies of the data.
(2) Addition of ECC or CRC by software or hardware.
