The mode of ON/OFF safety cabinet:

Block sensor on the cabinet door with hand, just can input password and be attended by green indication, the coding of password can adopt any rhythm pattern that is difficult for obscuring, after stopping input, controller is discerned automatically, if the password input is correct, can show green, safe door is opened automatically simultaneously; If the password input error can show redness, refusal is unblanked.Need are closed door tight with hand and were kept 1 second at closing time, treat to loose one's grip after yellow demonstration is extinguished again.

Revise password:

Block sensor and keep more than 3 seconds, luminous tube stops to block when becoming yellow by green, yellow demonstration can be extinguished, in 3 seconds after this, should input the password that stored to check by qualification, password mistake or this moment do not continue to input password all will cause warning, show red and block the scheduled time; If password is correct, then check (when using for the first time program can judge automatically do not deposit password in the cryptographic libraries as yet in skip qualification and check) by qualification, have yellow the demonstration once, can continue the step of following modification password:

1. yellow the demonstration once, setting code storehouse number

Safety cabinet is provided with 10 cryptographic libraries (being equivalent to have 10 keys), corresponds to certain storehouse according to blocking number of times, and promptly blocking once is first storehouse, and by that analogy, green repeats to show automatically.

If ▲ misspecification cryptographic libraries can cause existing password to be capped.

▲ when yellow shows one time, if untimely setting code storehouse number then can be automatically brought to parameter and set (back detailed description).

2. the yellow secondary that shows, degree-of-difficulty factor is set

The identification degree-of-difficulty factor of safety cabinet is 1 to 9 grade, determines degree-of-difficulty factor according to blocking number of times, and the big more recognition code of numeral is strict more, and the client can set up on their own according to mode of occupation.After setting was finished, green repeated to show automatically.

3. yellow the demonstration three times, the new password setting

The input new password blocks time number limiting in 19 times, and after the new password input was finished, green repeated to show automatically.

4. yellow the demonstration four times, confirm new password

Repeat to import new password, relatively whether the password of the 3rd step, the 4th step twice input is identical automatically for controller: as inequality, and red display, it is invalid that new password is set; As identical, confirm that then new password is effective, green flicker, so far new password is set and is finished.

Parameter is set: (when yellow shows one time, if untimely setting code storehouse number then can be automatically brought to here.)

5. yellow the demonstration five times, allow the runin number of times to set

Allowing the runin number of times is 1 to 255 time, and the client sets up on their own.After setting was finished, green repeated to show automatically.

6. yellow the demonstration six times, the blocking time setting

The warning blocking time is 1 to 255 unit, and each unit is 10 seconds, and the client sets up on their own.After setting was finished, green repeated to show automatically.
