Function
Red spring-loaded button for zeroizing the key stores and crypto
memory in case of emergency.
The button must also be used for switching off the hold batteries
when AROFLEX is disconnected from the mains and the contents of
the crypto memory are to be zeroized. Pushing the button extinguishes
the drain indicator (25).
Lock for inserting and turning the physical INSERT key for key-
setting purposes.
Red light-emitting diode, lit when the "hold" batteries are being
drained to retain the contents of the key compartments and crypto
memory (for instance during interruptions in the power supply).
The fully charged hold batteries keep the memory alive for about
90 minutes. The indicator lights up as soon at the plug is pulled from
the mains. The hold batteries are switched off automatically when
the output voltage drops below a certain threshold.
The hold batteries are constantly trickle-charged as long as AROFLEX
is connected to the mains. The indicator is extinguished when the
"Zeroize" button (23) is pushed.
For connecting a stand-alone tape punch.
For connecting a stand-alone tape reader.
For connecting the warning lamp and shunt device in the line-connected
mode.
