13. CAUTIONS ON USE
Please be noted that we do not guarantee proper performance of the card reader if it is used other than
the indicated specification range.
13.1 During installation
(1) Do not drop or bump anything against the card reader. Otherwise, failure may be the result.
(2) Do not touch the P.C.B. with bare hands.
(3) Be sure to install on a flat surface so as to prevent any force to be applied to the card reader
during installation.
(4) Avoid installing the Card Reader in the following environment.
* Watery, humid or dusty place.
* Near machines which generate magnetic field or inducted noise. (Printer ,LED display, CRT etc.)
* Place which gets direct sunlight.
13.2 During use
(1) Be sure to use a card which conforms to ISO standard. Anti-magnetic of the
applied card should be 2.4
ﾗ
10
A/m
2.4
ﾗ
10
A/m of ISO standard.
(2) Card operation speed should be within the specification range. Forced stop or
change of speed during the card operation may cause a read error. Appropriate
speed to maintain stable operation is 30 cm/s
60 cm/s.
(3) Store the card with caution to prevent dirt, scratch and distortion. No foreign
matter should be stuck on the magnetic stripe surface. Use of such card may
result in a read error.
(4) Insert a cleaning card and clean the head periodically to prevent wearing of the
magnetic head. Head cleaning using the cleaning card should be performed
about once a week if the room is not dusty.
(5) Enviroment conditions such as external noise or electrostatics etc. may affect
operation of the card reader and interface. Check the level of noise resistance
and electrostatic resistance of your factory before using the card reader.
