Chamberlain 940CB User guide

Features

For use with any SECURITY✚ compatible garage door opener receiver.

Personalized Password: Up to 10,000 possible combinations. Password can be easily changed if desired.

Temporary password: Can be added for visitors or service persons. This temporary password can be limited to a programmable number of hours or a programmable number of entries.

Rolling Code: While your password remains constant until you change it, the code between the Keyless Entry and the receiver changes with each use, randomly accessing over 100 billion new codes.

Operation: Opener activates when 4-digit password and Enter button is pressed.

If wrong numbers are accidentally pressed, correction can be made immediately. The Enter button will transmit only the last four digits.

The Keypad will blink for 15 seconds after the password is transmitted. During that time the Enter button can be used to stop or reverse the door travel.

Installation

Choose a convenient location for installation. It should be at eye level, reachable by the shortest person who will use it, and within sight of the door.

For a one-piece door, choose the optional location shown in the illustration (on the edge of the door jamb) to avoid injury as the door swings up and out.

Test the reception of the Keyless Entry by operating your opener from the selected location. Change the location if necessary.

Remove the battery compartment cover to access the bottom mounting hole:

• Insert a small phillips screw driver into the small hole at the bottom of the cover and gently pull outward to loosen.

• Slide the cover down to remove.

Center the keypad at eye level against the selected location. Mark 4-1/4" up the centerline from the bottom and drill a 1/8" pilot hole. Install top mounting screw, allowing 1/8" to protrude above surface. Position keypad on screw head and adjust for snug fit.

With cover open so bottom mounting hole is visible, use a punch to mark hole. Remove keypad and drill 1/8" pilot hole. Replace keypad and complete installation with bottom screw, using care to avoid cracking plastic housing.

Do not

overtighten.

To replace the battery cover, insert the lip at the top and snap in place.

Side two contains instructions for changing the personal entry password and setting a temporary password.

hold

the Enter button. The indicator light on the door

opener panel will blink.

Setting a Temporary Password

In addition to your personal entry password which works at all times, a 4-digit temporary password can be added for the convenience of visitors or service persons. This allows authorized persons a way to gain temporary access. After a programmed number of hours or number of accesses, this temporary password expires and will no longer open the door. The temporary password can be used to

the door even after it has expired. To set a temporary password:

1. Press the four buttons for your personal entry password (not the last temporary password), then press and hold the ✽ button.

The opener light will blink three times. Release the button.

2. Press the temporary 4-digit password you have chosen, then press Enter.

The opener light will blink four times.

3. To set the number of

hours

this temporary password will work, press the number of hours (up to 255), then press ✽.

3. To set the number of

times

this temporary password will work, press the number of times (up to 255), then press #.

The opener light will blink once when the temporary password has been learned.

Test by pressing the four buttons for the temporary password, then press Enter. The door should move. If the temporary password was set to a certain number of openings, remember that the test has used up one opening.

To clear the temporary password, repeat steps 1-3, setting the number of hours or times to 0 in step 3.

The 9 volt battery should produce power for at least one year. Replace when the keypad illumination becomes dim.
