Audio Feedback
Audio feedback is available through a non-oscillating beeper for keystrokes and operation alerts. The
beeper device provides a single pulse for audio feedback recognition of each key press. The beeper
can be given a time and frequency command to produce modulated tones. The beeper is capable of
producing a 75db sound level at 1 foot.
3.6
Battery
The battery provides power to maintain the contents of cryptographic keys while power to the unit is
off. For maximum security, the battery power is cut off during a “tamper event” condition, which
causes the erasure of the cryptographic key(s). The battery is not in use when the unit is powered by
an external source.
