The 2740B allows you to dial directly to a combination
number without counting dial revolutions for every entry.
Whenever you are dialing to a number, it is important to
avoid “overshooting” the number, then backing up to it. If
you overshoot the number, you can continue rotating the dial
in the same direction for an extra turn (or two, or three, or
more), then stop precisely on the desired number. Unlike
a mechanical lock, the dial can be rotated any number of
rotations for entry of any combination number.
If adjacent combination numbers are within two numbers
of each other (26-24-3 for instance), don’t dial the short
distance directly to the second number, but turn a full
revolution, then dial to the number.

Single user mode
simply means that one combination opens the
lock. The
opening index
is the mark at the top of the dial ring at
the 12 o’clock position. Follow this procedure:
1. Turn the dial left (counterclockwise) at least two complete
revolutions, then stop precisely on the first number of the
combination.
2. Turn the dial right (clockwise), stopping when the second
combination number comes to the opening index.
3. Turn the dial left, stopping when the third combination number
comes to the opening index.
4. Turn the dial right. If you have entered your combination
correctly, the dial will come to a positive stop before you have
turned more than two revolutions.
If the lock emits 10 beeps upon opening, both lock batteries
must be changed. The 10-beep low battery signal will
repeat every twenty seconds for one minute after the lock is
dialed open.
To re-lock the 2740B after the container is closed and its handle
is turned to the fully locked position, turn the dial at least ½
revolution left (counterclockwise).

Dual user mode
simply means that two different combinations
are needed to open the lock. Typically, each combination is held
by a different person for security reasons. Either combination can
be entered first. Both combinations must be entered within two
minutes.
The
opening index
is the mark at the top of the dial ring at the
12 o’clock position. Follow this procedure:
1. Turn the dial left (counterclockwise) at least two complete
revolutions, then stop precisely on the first number of the 1
st
combination.
2. Turn the dial right (clockwise), stopping when the second
number of the 1
st
combination comes to the opening index.
3. Turn the dial left, stopping when the third number of the 1
st
combination comes to the opening index. Turn the dial right
about ten numbers. The lock will emit four quick beeps.
4. Turn the dial left (counterclockwise), stopping when the first
number of the 2
nd
combination comes to the opening index.
5. Turn the dial right (clockwise), stopping when the second
number of the 2
nd
combination comes to the opening index.
6. Turn the dial left, stopping when the third number of the 2
nd
combination comes to the opening index.
7. Turn the dial right. If the two combinations have been entered
correctly, the dial will come to a positive stop before you have
turned more than two revolutions.
Note: If either of the two combinations have not been dialed
correctly, the lock will emit a brap (one long beep). Follow steps
1-7 again, making sure the correct combinations are dialed
precisely to the opening index.
If the lock emits 10 beeps upon opening, both lock batteries
need to be changed. The 10-beep low battery signal will
repeat every twenty seconds for one minute after the lock is
dialed open.
To re-lock the 2740B after the container is closed and its handle
is turned to the fully locked position, turn the dial at least ½
revolution left (counterclockwise).
