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

___________________________ 5____________________________
DL220A and DL220AT Operations Manual V3.0
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.

___________________________ 10 ____________________________
DL220A and DL220AT Operations Manual V3.0
5.3.6. Test by first closing the cover and letting the lock power off by
either pressing the POWER button or waiting until the lock
timesout.
5.3.7. Open the cover, place your finger on the window exactly as
you had earlier, listen for 2beeps and a flash of green light. That
means your fingerprint was recognized and the lock will
unlocked.
5.3.8. If you hear 3beeps and see a red light, your fingerprint was
not recognized. Close the cover, and then try again from 5.3.7.
5.3.9. Hint: If you have lots of difficulty activating the lock and your
rejection rate is more than half the time, consider re-registering
your fingerprint with a different finger, different
pressure/position, etc. To do so, apply astart up or mass delete
per Section 9.1 or Section 9.2.Then start over from 5.3.1.
5.4. Procedure for registering additional fingerprints:
5.4.1. An Administrator must first gain access to the lock with his
fingerprint (Ref. Section 5.3.6 or Section 7) or with an
administrative passcode (Ref. Section 08)
5.4.2. Listen for 2beeps, after which you have ten seconds to
proceed.
5.4.3. Press the SAVE(4) button for about 3 seconds until you hear a
long beep (The display will show “xx”, designating the ID
number that will be registered next)
You can cycle through the categories by pressing the
SELECT(2) button. If the fingerprint you want to register is in
the User category, you would stop at the numbers between #06
and #50.
For example, if you see: 3–7displayed, that means you have
already registered two Administrators and one User. By default
it will select the next User ID number available.
5.4.4. Follow the procedure starting at 5.3.4 for more fingerprint
registrations.

6. Registering Passcodes(must be 7-digits long)
6.1. First: Gain access:
6.1.1. If the lock has not had any fingerprints registered yet, power
up the lock with the POWER button –wait for the display to
show “0”, or
6.1.2. If there has been an Administrator already registered, the
Administrator must first gain access by using fingerprint (See
Section 7)or Passcode to gain access(See Section 8).
6.2. During the next steps, keep the fingerprint detection window cover
CLOSED.
6.2.1. Press the SAVE(4) button and hold for about 3 seconds until
you hear a long beep and see “xx” in the display signifying the
ID is about to be registered. (Reference Para. 2.6)
You can cycle through the categories by pressing the
SELECT(2) button. If the passcode you want to register is in the
User category, you would stop between #06 and #50.
6.2.2. Press and hold the SAVE(4) button for about 3 seconds again
until the display shows “0”.
6.2.3. You must now enter your 7-digit passcode twice.
(Note: While entering your passcode, the display will count
your digits for you so you know when you get to 7 –it is not
showing what digit you are entering.)
6.2.4. After entering the passcode the first time, you will hear a beep
and see “0” in the display again. That is when you enter the
passcode a second time for confirmation.
6.2.5. When you hear 2beeps, the passcode is accepted. The display
will show the next available ID number.
6.2.6. If you hear 3beeps, your passcode was not accepted. In most
case it is because the two passcodes you entered do not match
and you should repeat from step 6.2.3 until the two passcodes
match. If you timed out, you can start from step 6.1.

7. Unlocking the Door with a Registered
Fingerprint
7.1. Open scanner cover
7.2. Press finger firmly on the scanner window exactly as you did during
registration and wait…
7.3. If successful, you will hear the lock mechanism and 2beeps. You also
will see the green light flashes. You will have about 10 seconds to
push down on the door handle, after which it will automatically lock
again.
7.4. If there are 3beeps, the fingerprint was rejected. This means the
finger was positioned and/or pressed in a way that did not match the
registration. Close the cover, then open cover and try again. With a
little practice, you will unlock the door every time. (Note: Section 10)
describes how to set the threshold level, and how to trade-off ease of
acceptance with tight security.)

___________________________ 13 ____________________________
DL220A and DL220AT Operations Manual V3.0
8. Unlocking the Door with a Registered Passcode
8.1. Press the Power button (bottom-most button)
8.2. Wait for a “0” to appear in the display
8.3. Punch in a 7-digit passcode that was previously registered.
8.4. When you hear 2beeps, the door is unlocked. You have about 10
seconds to open the door.
8.5. Otherwise if you hear 3beeps, and see “0” in the display, that means
the passcode is not correct. You have 4more chances to reenter the
correct passcode.After five erroneous tries, the lock will be
disabled for 5minutes!

___________________________ 14 ____________________________
DL220A and DL220AT Operations Manual V3.0
9. Deleting Fingerprints
9.1. Mass Delete
9.1.1. First, an Administrator must gain access to the lock, either
with fingerprint or passcode.
9.1.2. Press DEL(3) and SAVE(4)simultaneously for about 3
seconds until you hear 2beeps and display shows UU.That
means all users been deleted.
9.2. Special Start up Delete
If only one or two Administrators have been registered and no other
Users, both Administrators can be deleted by simply pressing and
holding the DEL(3) and POWER buttons for about 3 seconds until
there is a long beep and display shows UU. This returns the lock to
its start up condition and is for the convenience of first time users
during the training period.
9.3. Deleting individual fingerprints
9.3.1. Administrators can delete anyone. Users cannot delete.
9.3.2. The Administrator must know the ID number of the person
being deleted.
9.3.3. The Administrator must first gain access to the lock with his
fingerprint (Ref. 7or with an administrative passcode (Ref. 8)
9.3.4. Press the DEL(3) button and hold for about 3 seconds till hear
a long beep.Display will display a registered ID.
9.3.5. Press the SELECT(2)button to cycle around to the ID of the
passcode or fingerprint to be deleted.
9.3.6. Press and hold the DEL(3) button for about 3 seconds until the
display goes blank.
9.3.7. That individual has been deleted.
9.3.8. The display returns with registered IDs again; others can be
deleted by repeating the procedure starting with 9.3.5.

10. Setting Security / Threshold Level
10.1. As explained earlier, fingerprint recognition is not a black and
white process like a key or entry of a passcode. Rather, it is a variable
for which the user can set the level of recognition criteria.
10.2. Five triggering thresholds are available: S0 through S4. The
lowest level, called the Training Level, is S0, with increasingly more
stringent thresholds up to S4.
At S0, the algorithm matches a minimal number of fingerprint
characteristics and therefore is more forgiving in terms of exact
placement of finger, dirt on the finger, and image quality, etc. It also
means there is the risk that a random fingerprint could be matched
with a registered image, although any stranger to the system would
have to know the buttons to push and the procedure used to open the
door.
At S4, the fingerprint image must match perfectly with a registered
fingerprint, which means there is no risk of a false acceptance, but the
users must learn to place their fingers consistently and present an
excellent image in order to be admitted. S1 through S3are
intermediate levels.
10.3. In addition to the direct setting of threshold level for the lock,
thereby determining ease of entry for fingerprint access, there is also
an indirect way to make entry easier without sacrificing security. You
can register a user many times with the same finger as if he/she is
many people. If a person has programmed a finger many times with
slight variations in position or pressure, there is a higher probability
he/she will be recognized when trying to open the door.
10.4. Only one security level is set for the lock at a time. Different
security levels cannot be set for different individuals.
10.5. Setting Security Level
10.5.1. If you have a new lock and no fingerprints or passcodes have
been registered, press POWER button once -- wait to hear 2
beeps, then skip the next step and go to 10.5.3 below.

___________________________ 16 ____________________________
DL220A and DL220AT Operations Manual V3.0
10.5.2. If there are Administrative passcodes or fingerprints already
registered, ether use the passcode or fingerprint to gain an access
(refer to section 7and section 8)
10.5.3. Press and hold three buttons SELECT (2), DEL(3), and
SAVE(4) all together -- wait to hear a long beep, then see the
levels of security Sx(e.g. S0) on display.
10.5.4. Cycle through the Levels with the SELECT(2) button.
When starting out, set Security Level to level 0by stopping at S0 on the
display and pressing the SAVE(4) button and hold it for approximately 3
seconds till the display goes off and 2 beepssound.
