Maintenance and Inspection

The V750 Series Reader/Writer and Antenna must be inspected on a daily or regular basis so that the
functions of the V750 Series can be used in good condition.
The V750 Series consists of semiconductors that last almost indefinitely. The following malfunctions may,
however, result due to the operating environment and conditions.
1. Element deterioration due to over voltage or over current.
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.
