Persons fitted with a medical device should keep the device’s fitting portion more than 22cm away
This equipment is RFID (radio fiequency identification) equipment which uses radio waves Therefore, It may
afi'ect a medical device depending on the use application or place. In order to minimize the efi'cct’, please
observe the following during operation:
Persons fitted with an implanted medical device should keep the fitting portion more than 22 cm away from the
antenna portion of this equipment.
Carefully perform such operation as changing attribution or key of card
The card must securely stay in the Reader/Writer detection area while the card attribute or key IS being changed.
Should this special data area be destroyed due to insufiicient power supply, access to this card will not be available.
Keep a metal body away from a card and Reader/Writer
The Reader/Writer supplies power to a card by electromagnetic waves to communicate with it. Ifthere is a metal
body near a card or on the antenna portion of the Reader/Writer, electromagnetic waves will he cut off or
absorbed Therefore, conununicatic'm with the card or. sufficient power supply may become difficult to perform.
As a result, the access area will be reduwd or the eqmpm’ent will fall mto an inaccessible state.
When operating the Reader/Writer, keep a metal body away from the antenna portion of the Reader/Writer:
(The circuit board IS equivalent to a metal body. Be carefiil when mounting positions of the antenna portion and
another substrate)
Do not use Reader/Writer in a place where strong electromagnetic waves are produced
The Reader/Writer supplies power to a card by electromagnetic waves to communicate with the card. Therefore,
the access area may be reduced or the equipment may fall into an inaccessible state due to difficult communication
between the Reader/Writer and a card if there are strong electromagnetic waves (especially near 106 kHz, 847
kHz, or 13.56 MHz) near the Reader/Writer or a card.
Keep precision electronic equipment affected by electromagnetic waves away
Electromagnetic waves (near 13.56 MHz) are always output fiom the Reader/Writer: Therefore, bringing
precision electronic equipment afl‘ected by electromagnetic waves close to the Reader/Writer may cause the
malfirnction or failure of the equipment. When operating the Reader/Writer, keep such precision electronic
equipment away-from it.Should you need to bring precision electronic equipment close to the Reader/Writer, take
countermeasures s'ixch as by shielding the precision electronic equipment wifl1 a metal body. In addition, make
sure to commit a test to verify that there is no eflect.
Installation of multiple Readers/Writers at close range
The Reader/Writer supplies power to a card by electromagnetic waves to communicate with the card. Therefore,
electromagnetic waves (near 13.56 MHz) are always output from the Reader/Writer. Therefore, installing multiple
Readers/Writers at close range causes mutual interference, making communication between the card and each
Reader/Writer unavailable. ' , _‘ When installing them at close range, check the presence or absence of
interference before operating them.
Do not attempt to access multiple cards at the same time.
This Reader/Writer is manufactured on the precondition that there are no multiple cards in the access area of
the Reader/Writer at the same time. If you attempt to accees multiple cards at the same time, normal access
may not be made or card detectiOn may become unavailable, although this depends on the relative positions of
the Reader/Writer and'mnltiple cards.
