MANY CODES TO CHOOSE FROM
The code chamber consists of 9 buttons from which the code is selected,
and a 'C' button which is used to re-set the chamber after an incorrect entry,
and which must always be used as the first digit of a code. Buttons may only
be used ONCE in a code. For example, 1212 is not possible.
A code or combination can be entered in any order or sequence; e.g.
1234 can be 4321 or 1342 or whatever sequence is most convenient to
remember. With 9 buttons, a total of 511 different codes are available,
any of which can be entered in any sequence.
The total is arrived at as follows:
+ 1 digit = 9 codes
C
+ 2 digits = 36 codes
C
+ 3 digits = 84 codes
C
+ 4 digits = 126 codes

It is recommended that the code is changed regularly to
prevent compromise.
CODE CHANGE INSTRUCTIONS
1 Remove the lock from the door by unscrewing the 2 screws in
the back plate.
2 Press the 'C' button to reset the chamber and place the lock case
on a flat surface with the buttons down.
Remove the 2 red screws and carefully lift off the code chamber
3
plate. Check that all 10 springs are held in place on the plate.
Note that the coloured code tumblers correspond in position
4
to the existing code. The silver non-code tumblers fill the other
positions. The C tumbler is not coloured.
Hold the lock in your hand and depress the 'C' button. Keeping
5
the 'C' button depressed, use tweezers to reposition the tumblers
to correspond with your new code. The square notches of ALL
tumblers MUST face outwards, with the square tips ON TOP: See
diagram below. DO NOT force the tumblers in.
NB: Holding the 'C' button depressed whilst re-positioning
the tumblers is ESSENTIAL to avoid damaging the internal
mechanism. DO NOT attempt to reposition the 'C' tumbler.

MAINTENANCE
No maintenance of the working parts is necessary. DO NOT OIL.
To maintain the finish the lock should be cleaned regularly with a
soft cloth. A silicone spray or similar, should be used to provide a
protective film against grit and grime.
