Revision 2.0
These LEDs (Figure 3.2) are an indicator of the remaining storage capacity of the installed RMC.
There are 5 LEDs: 3 GREEN, 1 AMBER, and 1 RED. When all 5 LEDs are on, this indicates that
there is approximately 80% to 100% of RMC storage capacity available. As storage is utilized in
the RMC the LEDs will be extinguished in succession starting from left to right. LEDs may take up
to a minute to change state when capacity remaining crosses the thresholds.

3.2.1
Key Clear Button
When this button is pushed and held for a minimum of 5 seconds, all encryption related material
within the DTS1 will be erased. This includes loaded keys, stored keys, and all previously loaded
login/authentication credentials (user names and passwords). After zeroization, the yellow KEY
LOADED LED will turn off. In order to use the unit again the encryptor will require reinitialization
and any previously loaded credentials and keys to be reloaded.
3.2.2
Write-Enable Switch
The write-enable switch (Figure 3.3) is used to lock the USB flash memory so it cannot be
inadvertently changed. The switch is placed in the READ-WRITE position to configure the flash
memory. After the configuration is set, the switch is moved to the READ position.
