10-1 Maintenance and Inspection
The Reader/Writer must be inspected on a daily or periodic basis so that the functions remain in good
condition.
The Reader/Writer consists of semiconductors that last almost indefinitely. The following malfunctions,
however, may result due to the operating environment and conditions.
(1) Element deterioration due to overvoltage or overcurrent.
(2) Element deterioration due to continuous stress caused by high ambient temperature.
(3) Connector contact faults or insulation deterioration due to humidity and dust.
(4) Connector contact faults or element corrosion due to corrosive gas.
