DL220A and DL220AT Operations Manual V3.0
2. Definitions and Explanations
2.1. Outside –The side of the lock that would be on the outside of the
locked room or house. On this side is the scanning window, the
display and the five buttons.
2.2. Inside –the side of the lock opposite from the Outside.
2.3. Registering, Enrolling or Programming of Fingerprints –This is
the process of acquiring the image of fingerprints of authorized
persons and storing them into the lock’s memory. Two images of each
finger are scanned in the process, with the same finger being placed
two separate times on the window. (Section 5)
2.4. Power Off/Time Out –The lock maximizes both security and battery
life by automatically powering off if no action is taken for 5 to 10
seconds (depending on function), which the user will hear as a motor
noise inside the lock. During the fingerprint registration and other
programming functions, the time out function requires you to move
quickly in the programming sequence. Delaying too long will mean
you must start over in the sequence.
2.5. Security Levels –Five thresholds are available for users to optimize
convenience versus security for their particular application. (Section
10.2)
2.6. Management Levels –The DL220A has TWO permission levels:
Administrator, and User. They are designated and identified by ID
numbers that correspond to their stored fingerprints or passcodes as
follows:
2.6.1. Administrators: ID numbers 01 through 05
2.6.2. Users: ID numbers 06 through 50
2.6.3. In general, the Administrators can add/delete their own level
and user level IDs and mass-delete all stored fingerprints and
codes.The User only can unlock the lock.
2.6.4. The first people Registered will be automatically assigned
Administrator IDs. The first Administrator can register a
secondary Administrator ID. Thereafter, either of the first two
