Fitting Instructions
The Digital Combination Lock can be fitted to cupboards, cabinets and lockers etc as a direct replacement for existing cam locks or for the Lowe & Fletcher 3751 Digital Combination Lock. It can also be easily fitted to cupboards and cabinets that do not have an existing locking device.
Special Notes
Before installing the Digital Combination Lock, load the batteries and familiarise yourself with the operation and programming.Unless manufactured to special order, the lock is supplied in the “PRIVATE” operating mode.In this mode, the user must enter a four-digit User Code to open it. The unit will re-lock itself after four seconds. The lock can be opened at any time using the Master Code.Unless manufactured to special order, the defaultMaster Code is 11 33 55 77 and the default User Code is 22 44. These codes are common to all standard locks and it is very important that you set your own personal Master and User Codes.Your lock is not secure until you have changed the default Master Code and User Code.Keep a safe record of your master code as it is not possible to make any programming changes without it.Please see programming guide to set your own codes.
