Operation LED
The Op-LED is a surface mount, tri-color LED, which is visible from the back of the housing (using
a light pipe)
.
It is molded into the housing. The LED provides operating information for the PIN Pad.
The following chart gives operation status meanings. The blink rate is about 12 times per minute
with an LED-on period of about 2.5 second.

Tamper Protection Features
The unit incorporates anti-tamper features, consisting of small buttons on the left and right edges of
the housing (and two internal buttons, not accessible from the outside). When these buttons are
depressed and the unit has been anti-tamper enabled via software commands (see
), any sudden release of tension on the buttons causes the unit to deactivate. (Also,
cryptographic keys will be erased
.) Thus, unauthorized removal of the unit (theft, disassembly, etc.)
will cause deactivation and make it impossible for sensitive data to be accessed or for the unit to be
(re)used by an unauthorized user.
