1. Introductory Notes
1.1. As with many advanced technologies, the use of biometrics for
identification involves a learning process. The DL220A uses exciting
technology and design that allows the opening of a locked door simply
by pressing a finger on the lock, but users must learn the best
positioning and pressure to use.
1.2. Generally, the center of the vortex of the fingerprint pattern is the key
data point; ideally, it is placed in the center of the small glass window
in a consistent way. Your finger should be flat, motionless and held
with firm pressure in the same way each time. See some guiding
drawings on next page.
1.3. A very firm pressure when placing the finger gives the best image, but
the finger must not move during scanning.
1.4. Moist fingers give better images than dry ones. If on cold, dry days
you have difficulty, for example, try moistening your finger with your
breath or a little moisture.
1.5. Dirty fingers are obviously not recommended, not only because the
fingerprint might not be clearly seen but because there is a risk of
scratching the window.
1.6. The DL220A allows setting of security thresholds to determine how
precisely you must place your finger to open the lock, thus giving
customers a range in the tradeoff between security and convenience.

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

Administrators can designate the level for each new registrant. If
no designations are made, the new registrants will be assigned
User IDsstarting with ID #06.

3. Basic Door Operation
3.1. Unlocking Door from Outside (Refer Section 7,8for details)
3.1.1. Using fingerprint: Open the scanner cover. Place your
registered finger onto window for verification. When the
fingerprint matches, two beepswill be heard. Use the lever to
open the door.
3.1.2. Using a 7-digit passcode: Press POWER button. Wait for the
display to show “0”. Punch in the passcodes. If it matches a
previously registered passcode, a sound and 2beeps will be
heard. Use the lever to open the door.
3.1.3. Using the emergency key: Pry off the cap on the handle with
a small knife or screwdriver. Insert key to open the door.
3.2. No Disturb Function
3.2.1. While the Power is OFF, press the black button at the top of
the lock on the INSIDE of the door. This turns off all power to
the lock and disables entry from the outside.
3.2.2. To return to normal operation, hold down the door handle on
the INSIDE until you hear a click, then power on the system
(ether press POWER button or open the scanner cover).
3.3. Door Always Unlocked Function
3.3.1. After you gain access, while Power is ON, press black button
at the top of the lock on the INSIDE. The lock now remains in
the unlocked position.
3.3.2. To return to normal operation, hold down the door handle on
the INSIDE until you hear a click, then power on the system
(ether press POWER button or open the scanner cover).
3.4. Quick Power Off
If you don’t want to wait for the lock to power off by itself after
unlocking or finished programming, you can press the POWER button
to short cut the wait for power off.

4. General Information and Hints
4.1. Before getting into the specific procedures, it might be useful to
explain the general scheme of the different operations.
4.2. Registering Users
Registering, enrolling or programming are different words to describe
the functionsof authorizing users for access to the lock (both for
unlocking and for changing users). Thesecan be done with passcodes
punched onto the buttons or by fingerprint. For each method, there are
two levels of users: Administrators and Users.
4.3. To enter the different programming modes, you must be an
Administrator and gain access to the lock, i.e. unlock it. This can be
done by previously registered passcode or fingerprint.
4.4. In general, after gaining access and before the lock times out, you
either press the DEL(3)OR SAVE(4) buttons. The lock makes a
long beep and allows you to enter programming modes and
functions using the buttons as follows:
4.4.1. The (1)button is for passcode #1 only.
4.4.2. The SELECT(2) button is used to select choices within other
button domains or passcode #2. It also can be used to check the
current user ID and available positions for more users.
Function Keys Basic Function
Passcode #1.
SELECT key. Also is passcode #2.
DELETE key. Also is passcode #3.
SAVE key. Also is passcode #4.
POWER key. Also is passcode #5.

___________________________ 8____________________________
DL220A and DL220AT Operations Manual V3.0
4.4.3. The DEL(3) button is used to enter the Delete function or
passcode #3
4.4.4. The SAVE(4) button is to enter the Enrolling function of
adding fingerprints or passcode #4
4.4.5. The POWER(5) button is the power on/off function or
passcode #5. When it is not in a passcode entry mode, it toggles
power on and off
4.5. In all modes, the lock will automatically power off if left idle for
about 10 seconds.
4.6. Sometimes it is useful to cycle around a series of choices while you
decide what to do next, thereby keeping the lock active so you don’t
time out and have to start all over again.
4.7. Since positioning, pressure and condition of your finger are important
in opening the lock, it may take a little practice to be consistent. It is
possible (and sometimes recommended) for individuals to program
their fingers several times, especially if they have weak fingerprint
images and/or have difficulty getting accepted. Multiple images of a
fingerprint in storage increases the chances of making a match the first
time.
Also, it is possible for an individual to register more than one finger if
it is anticipated that his/her fingers could be taped, scarred, etc.
4.8. The bottom-most button (POWER) is the Power On button for using
passcodes and lifting the cover is the Power On switch for using
fingerprints.
4.9. The top push-down button on the inside of the lock disables all
functions. Entry from the outside is then no longer possible. To return
to normal operation, you must operate the door handle on the INSIDE
until you hear a click.
4.10. The small Phillips screw in the inside of the door holds the battery
cover, under which are the 6 AA batteries.
4.11. Wait for the Power Off tone when going from one programming
sequence to another, or to enter a different function.

5. Registering Fingerprints
5.1. On the first two registrations, there is no need to assign management
levels as they will be assigned Administratorsautomatically, but on
subsequent registrations, have in mind what level you wish to assign,
by using the different range of ID numbers described above. (Review
Para. 2.6 above.)
5.2. Hint: Before starting, decide what finger you wish to use and
practice placing the finger onto the window in the same way you
intend to open the door later. Practicing will give you a feel for the
window and help you be consistent in how you place your finger each
time.
5.3. Procedure for registering first Administrator:
5.3.1. Open cover, which powers on the lock for fingerprint
operation.
5.3.2. Listen for a long beep. (With no fingerprints or passcodes
registered, the door will unlock and remain active for about 10
seconds.)
5.3.3. Press the SAVE(4) button and hold for about 3 seconds until
you hear a long beep.(The display will show “01”,designating
the first Administrator ID)
5.3.4. Place your chosen finger on the window and with your other
hand press and hold SAVE(4) for about 3 seconds until you hear
a long beep and the red light blinks. Your finger will be scanned
once.
5.3.5. When you hear a short beep, remove and reposition your finger
quickly for asecond scan. You will see the red light flash again
and when you hear 2beeps and see a green light come on, your
fingerprint has been accepted, stored and you are registered. If
you hear 3 beeps, the second scan was not accepted and you need
to repeat the two scans again. Just hold the SAVE(4) button
again, repeating Section 5.3.3 and be sure to hold your finger
firm and steady on the scanning window.
