For the way to change the code of KS550, pls see my note below.
Firstly, you have to use the KEY used for change the code (which supported when you buy the safe box)
Turn the dial clockwise and set : Turn the dail same the way of hand of clock.
Turn counter clockwise and set: Again the way of hand of clock.
On the edge of dail have two note: one for open and one for change the code.
Second, the way to change the code. For example : A – B - C
- Step 1: Open the door in normal way. After that, set the door in the closed position ( but the door still open)
- Step 2: Used the KEY, turn it into the hole at the back of the door.
- Step 3: Turn the KEY counter clockwise 90oD ( A quare angle)
- Step 4: come back the dail. Turn the dail counter clockwise, set A at the note for change the code: Four times
- Step 5: Turn the dail clockwise and set B at the note for change the code. Three times
- Step 6: Turn the dail counter clockwise and set C at the note for change the code. Two times
- Step 7: Come to the back side of the door. Turn the KEY clockwise 90oD (back to the original position) After that, put out it.
The way finish.
After changing the code, you should test it some with new code to open the door (open like nornal), with the door in the opened position.
If it oke, you can close the door. If not, pls kindly test with the original code and make those steps again.
Hope that, you can change it as you want.
