Troubleshooting
Cards won't be read properly.
Cause Voltage other than DC12V is used, or the type of the card is different.

2. See if the card is ISO14443 Type A or B type.
=> 125KHz cards can't be used. But, 13.56MHz cards can be used if they are
Solution
3. If the problem still persists, contact the service center.
When powered on, the reader beeps and the LED is dimly lit.
The power adapter being used is not capable of meeting the current consumption
Cause level of the reader, or the power cable is too long for sufficient power to reach the
reader.
1. Make sure to use an adapter with a capacity that is larger than the current
consumption level of the reader. If more than one reader is connected to one
single adapter, make sure that the capacity adapter can support the current
consumption of each reader multiplied by the number of the connected readers.
Solution 2. Even if the power source has sufficient capacity, the cable may not be an ordinary
power cable (i.e. communication cable, UTP cable, etc.) or the length is so long
that there is lots of power loss. In this case, replace the cable with a power cable,
or reinforce the cable.
3. If the problem still persists, contact the service center.
The read range of cards varies every time a card is read.
Even if the cards are of the same type, they might be produced by different
Cause companies and, therefore, have different characteristics.
(IDTECK cards are made according to the MIFARE card of Philips.)
1. Depending on the card manufacturer and special manufacturing processes, the
characteristics of the card may vary. Therefore, make sure that the cards are
manufactured by one company.
Solution If the cards are manufactured by different companies, it is natural that they have
varying read ranges.
2. If the read range of the cards manufactured by a single company varies, contact
the service center.
