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" settings
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 and press ; until multiple beeps are heard.
You are now in Program Mode.
2. Within 5 seconds (or current pass time interval),
press ; 99 ; 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 Program
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 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. Disconnect the battery pack.
3. Remove the back plate by unscrewing the two Phillips
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 ensure
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, re-
lease ;. If you do not hear these 6 additional
beeps, you must start over at step 2. Failure to follow
this exact procedure can result in erratic lock behavior.
7. Test by pressing the default Master Code of
123456 (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 spindle 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 nec-
essary 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. Pro-
ceed directly to page 12, Quick Start, and follow the
procedure "Enter Program Mode and Change Fac-
tory Master Code".
