5. Trouble Shooting

When powered up, this model take a self-test to ensure the best reading performance with the buzzer beeping continually. When the self—test ends, the buzzer will give out a long beep and the this model enter the normal working mode. If the buzzer continue beeping without stop for a long time, please turn off the power and check out the environment and power supply to ensure locating this model in a good working condition.

In case of problems the following procedure should be followed:

Failure to finish self-test with the buzzer beeping continually or with a short reading distance

• Turn off the power to this reader;
• Check the power input connections making sure that they are not reversed;
• Check the power supply complying with the specification;
• If the supply has a current limit , set this to 350mA;
• Make sure to install this reader in an environment without large area conductors nearby or mounting on a conductive surface. In self-test state, do not apply any tags in this reader’s functional area;
• Try to change the installment of the this reader to another place to check if the trouble still exists.
