How to use

Install the lock on a compatible cabinet or door following the manufacturer's mechanical fitting instructions, ensuring the mounting surface is flat and the fixing screws engage solid material. Set a numeric code according to the provided procedure before putting the lock into regular service. To open, enter the programmed code and operate the release mechanism; to lock, close the door or drawer and engage the locking action. Periodically check mounting screws and mechanical movement to confirm correct operation.

Usage recommendations

Choose a numeric code that is not easily guessed and change it whenever access needs change. Avoid exposure to prolonged direct moisture or outdoor weathering to preserve mechanical components. For installations in high-use areas, inspect moving parts and fixings at regular intervals and lubricate pivot points with a light machine oil if movement becomes stiff.
