Adjusting TimeLok XL

Timelok XL requires the inner door combination to adjust for Daylight Savings Time (DST). These procedures must be followed very carefully. Caution: An error in following these directions could result in an unintended combination change that will require faxed authorization to correct via factory override. For any unusual problems with DST, contact NKL Technical Service at (800) 452-4655.
