CL610 Code Change Guide
The CL610 has been designed so the code can be changed on the door in seconds.
The code chamber consists of 13 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 CL610 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 13 buttons, a total of 8,191 different codes are available, any of which can be entered in any sequence. Most people will set a code in the range of 4 to 7 digits, and the total number of codes in this range is 5,434. The lock is supplied with a random factory set code (see code change card supplied with lock). At any time this can be quickly changed to a new code of your choice.
Typically codes are 4 to 7 digits long. Shorter codes are possible (1-2 digits) but are not recommended.
Code Change Instructions
The CL610 model offers significant advantages over other similar mechanical digital locks by allowing the code to be changed in seconds on the door.
1. Choose code.
2. Insert key and turn anticlockwise to stop for right hand hung doors, or clockwise to stop for left hand hung doors. Fig 1.
3. Push the code change tool onto each button in turn, pushing in the buttons approx 2mm turn anticlockwise 180°. All buttons should now be in the non code position.
4. Test that all buttons are in non code position by depressing the lever handle which should retract the latch. If latch cannot be retracted press ‘C’ buttons and repeat step 3.
5. To select a button as a code button, push code tool over button. Press in button with tool approx 2mm and turn clockwise 180°. Fig 2.
6. Now turn the key clockwise for right hand hung doors, or anticlockwise for left hand hung doors retracting the latch which will relock the code buttons. Fig 3.
7. Return the key to centre and remove.
8. Before closing door test code.

Removal of front load cylinders to repin or replace with cylinders by a different manufacturer
1. Remove handle and cylinder cover
2. Turn key 90° anticlockwise and remove the cylinder from boss.
3. To replace cylinder, reinsert and turn 90° clockwise. Replace the cylinder cover and handle.
* If intending to use a cylinder from a different manufacturer it is advisable to confirm beforehand that the new cylinder will fit the boss.
Note that the CL610 uses a 6 pin screw cap cylinder. If using a screw cap cylinder other than supplied, the tail piece from the Codelocks screw cap cylinder will need to be fitted as follows:
4. Hold down the control pin in the end of the cylinder and unscrew the cap.
CAUTION! DO NOT INSERT THE KEY IN THE CYLINDER ONCE YOU HAVE REMOVED THE SCREW CAP.
5. Refit the tailpiece, hold down the control pin and screw the cap on fully without tightening. Ensure the control pin projects to lock the cap. 
Test the key operation
If the key is difficult to insert, or tight when turning, then the cap maybe too tight. Loosen the cap one notch at a time and try the key again. If the key inserts and turns OK, but is difficult to remove, then the cap may be too loose. Tighten up the cap one notch at a time. Adjust the cap until the key inserts, turns and removes easily.
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.
