11. Reader Verification:
The reader performs a self-test when power is first applied to the unit. If power-on test is successfully completed, the
reader will turn on both LEDs for approximately 1 second and sound the buzzer for 1 short beep. Then the reader is
ready for normal operation.
If further verification of the reader hardware is needed, the reader may be temporarily set to format 3. With this format
selected, the reader will read and verify standard ANSI track 2 encoded card. If no read error is detected, the green
LED will flash. Otherwise, the red LED will flash and the buzzer will sound two short beeps to indicate an error. The
LED input can be used to verify the LED function; and the buzzer input for the buzzer function. The reader will echo
a key press with a brief flash of both LEDs and a short beep of the buzzer. Reset to the required format for normal
operation after test.
12. Maintenance:
The reader is designed to provide continuous service with minimal routine maintenance. However, contaminants (such
as magnetic oxides from badges and dirt) tend to accumulate on the read head. Without regular cleaning, these
contaminants will shorten the read head life and increase the probability of card read error. A maintenance schedule
should be developed base on the card reader environment (dirty or clean) and the usage frequency (light traffic or heavy
traffic). Extreme case may require daily cleaning.
Head cleaning may be done by using a disposable, pre-saturated magnetic head cleaning card. These cards are readily
obtainable from a number of sources (e.g. Clean Team Co., www.cleanteam.com, 800-888-8830; KIC Products,
www.kicproducts.com, 207-514-7030; System ID, www.systemid.com, 888-648-4452).
The reader exterior surface is covered with high strength polymer and polyester membrane. It may be cleaned with
a soft cloth and mild detergent if required.
