Programming instructions

11
When a valid code is entered and the batteries are weak, the
red & green LED's will light and the sounder will sound for 4
seconds. The DL1200 uses two '123' Type Lithium batteries
(Duracell P/N CR17345). The lock will function with weak
batteries; however be sure to replace them as soon as
possible.
If the DL1200 is ever without power for less than 1 minute
(such as when replacing batteries), the DL1200 will continue its
operation undisturbed--programming remains unaffected due
to power provided by capacitors inside the lock. If the DL1200
is without power for greater than one minute, you have two
choices--you can (1) retain the lock programming or (2) erase
all programming. If you choose to erase all programming, the
DL1200 will revert to its original factory default configuration
("out of the box").
CAUTION: Do not press any keys while batteries are dis-
connected unless you intend to erase all programming.
1. Insert key in cylinder and turn counterclockwise to al-
low access to the battery compartment screw. With the
supplied 5/64" Allen wrench, loosen the battery cover
screw only until the battery cover is able to slide off.
2. Pull out the battery pack and quickly replace both
batteries - within 1 minute.
3. If you do not hear the 3 beeps when power is re-
applied, all programming and settings have been re-
tained, and the lock is ready for use. Go to step 5.
4. If you do hear 3 beeps when power is re-applied, do
not press any keys for 15 seconds. After the 15
second period, the LED will flash red 6 times and 6
beeps will sound. Reset the clock using functions 38, 39
and 40.
5. Slide the battery cover back in place and tighten the
screw.
If you accidentally press a key (or fail to replace the batteries
within 1 minute), use the Retain Lock Programming proce-
dure below:
Retain Lock Programming
1. Re-install battery pack.
2. Do not press any keys for 10 seconds.
If you do not hear any beeps or if you hear 3 beeps (one
per second), the previous lock programming is retained and
the lock is now ready for use. If you test the DL1200 and
find the lock programming is lost, you may erase all pro-
gramming and return the DL1200 to its original factory set-
tings, as described below.
Battery Replacement
Erase All Programming
RESTORE FACTORY DEFAULT (original "out of box" set-
tings that were set at the factory will be loaded).
1. Enter the current Master Code (if not known, proceed di-
rectly to ALTERNATIVE METHOD, below). Wait for the
green light. The lock will unlock.
2. Within 5 seconds (or current Pass Time interval), press
the function ; 000 ;.
3. Listen for 6 beeps. The lock will re-lock. All settings and
programming have been erased. Proceed directly to page
12, Quick Start, and follow the procedure "Enter Pro-
gram Mode and Change Factory Master Code".
ALTERNATIVE METHOD
Note: This method requires the lock first be removed
from the door.
1. Insert key in cylinder and turn counterclockwise to
allow access to the battery compartment screw. With
the supplied 5/64" Allen wrench, loosen the battery
cover screw only until the battery cover is able to
slide off.
2. Disconnect the battery pack.
3. Remove the back plate by unscrewing the two Phil-
lips head screws. Note: Some models have four
Phillips head screws. Be careful not to damage the
motor drive wires.
4. Locate jumper header JP1 near the top of the
printed circuit board and install the jumper (provided)
across pins 1 and 2 of JP1.
5. Press and hold down ; for 10 seconds (to en-
sure all power is drained from the lock) and release.
6. Connect the batteries and--within 5 seconds--press
and hold ;. After hearing 6 additional beeps,
release ;. If you do not hear these 6 additional
beeps, you must start over at step 2. Failure to fol-
low this exact procedure can result in erratic lock
behavior.
7. Test by pressing the default Master Code of
12345 (a beep will sound and
the lock will unlock).
8. Remove the jumper from JP1 pins 1 and 2 and
place jumper on 1 pin for storage.
9. Carefully reinstall the back plate STRAIGHT onto
the lock body. Be careful not to pinch or damage the
motor drive wires. While inserting the back plate, be
sure the rear pin of the tailpiece inserts into the spin-
dle hole--check this alignment after installation by
pushing on the spring-loaded tailpiece to verify that it
smoothly moves up and down. Replace the two (or
four) Phillips head screws to secure the back plate.
Note: It may be necessary to tighten the battery
screw previously loosened in step 1.
10. Re-mount the lock on the door. With the battery
back inside its compartment, slide the battery cover
back in place and tighten the screw.
All settings and programming have been erased.
Proceed directly to page 12, Quick Start, and follow
the procedure "Enter Program Mode and Change
Factory Master Code".
