Maintaining Your Sentinel Safe
While Sentinel safes are designed to make maintenance and service simple, the person performing it should be equipped with some basic mechanics and/or electronics skills.
Always closely follow repair and replacement steps to avoid electric shock and damage to the safe’s components.
