Diagnostic Mode

The keypad has a manual diagnostic mode built-in to verify proper keypad

function and troubleshooting key issues. This mode will not allow access to

any data or admin function. It can only be used to identify the rmware level

and to test button recognition.

To enter the diagnostic function:

1. Press UNLOCK, then press UNLOCK + 1, then press and hold 0 for ve

seconds. The RED and BLUE LEDs will blink alternately.

2. The BLUE LED will blink a number of times to represent the number of

both the major and minor revisions. The decimal point will be represented

by a single RED LED blink. Upon completion, the BLUE LED will glow

solidly. (Example: VERSION 4.1 would be indicated by four BLUE LED

blinks, one RED LED blink, one BLUE LED blink, and one RED LED blink,

then revert to the BLUE LED glowing solidly.)

3. To check the keypad’s button functionality, press each button and

the number of the button pressed will be expressed by the RED LED

blinking. (Example: 1 Button= 1 blink, 2 Button = 2 blinks, 3 Button = 3

blinks...0 Button = 10 blinks, Unlock Button = 11 blinks, Lock Button

= 12 blinks.)

4. To exit the Diagnostic Mode, wait for the 20 second timeout to return

the key to its normal operation.

Self-Diagnostics:

During the initial power up, after the key has been plugged into a USB

port, the key will perform self-diagnostics on the encryption algorithm and

critical hardware components. If the RED LED blinks at a rate of one blink

per second for 15 seconds, returns to standby and will not unlock, unplug

the key from USB port and try again. If the RED LED continues to blink in

the manner mentioned above and won’t unlock upon USB re-insertion, a

critical component has failed and the key can no longer function.

If the key blinks a triple-RED LED pattern that is repeated every two

seconds when unlocked, a failure has occurred that will not immediately

stop the device from working nor affect the security of the device, but

should be considered as a warning that the device needs to be replaced in

the near future. Additionally, Admin features may be limited in this mode.

If either condition should appear, remove the key from the USB port and

allow the key to go to sleep, and try to unlock the key again. The event of

either diagnostic failure will be very rare, but if the key cannot recover, it

must be replaced.
