Garage Door Opener Remote Control Delta 3 DTD Programming Instructions

Single-channel Digital Receiver and Transmitter

Code Setting and Installation Instructions

The Delta-3 digital receiver and transmitter is a single-channel wireless radio control designed for use with automatic garage/gate operators and access control systems. All Delta-3 products (on the same frequency) can be mixed and matched to suit your individual needs.

The Delta-3 radio format provides 256 different digital codes. The codes are set using the 8-position coding switches in the units.

Caution: All transmitters and receivers should be recoded prior to operation.

In order to avoid the possibility of duplicating codes in adjacent systems, factory set codes should not be used. In addition, among the valid codes available, four others should not be used. These include: all keys set ON or OFF and keys set alternating ON/OFF.

Where a number of receivers are to be installed in close proximity (as in an apartment complex), install receivers at least 5 feet apart. If receivers are installed closer than 5 feet apart, blocking may occur.

After completing an installation, operate the transmitter outside the building and check to see that the coded signal being used does not interfere with neighboring garage door operators and/or security systems. If interference is detected, select another code and check coded signal again. Repeat if necessary.

Step 1 Locate Coding Switches. Locate the digital coding switch for the receiver which is recessed in the center of the back of the case. The transmitter coding switch is accessed by removing the battery access door located on the back of the transmitter case. The keys are numbered 1 through 8. The switches in the receiver must match the switches in all transmitters used to operate the receiver.

Step 2 Code Transmitter and Receiver. Use a paper clip or other pointed object (except a pencil or pen) to pick any combination of ON/OFF codes and set them on switch keys 1 through 8 on the receiver and transmitter. The ON position is when the top of the switch is down. The OFF position is when the top of the switch is up and the bottom is down.

Step 3A Connecting receiver (using transformer power). Where it is not feasible to obtain power from the operator, connect a model 524 transformer (accessory) to the receiver as shown below. Then plug the transformer into a convenient (unswitched) 110 VAC outlet.

Step 3B connecting receiver (using operator power). Connect the receiver to the garage door or gate operator as shown in the diagram. Power will be supplied from the operator.

Ste3p 4 Remote Mounting. A mounting clip is packaged with each receiver. To install the receiver, Attach the clip to the mounting surface with screws. Position the two rectangular holes on the back of the receiver over the clip and snap the receiver down into place.


Linear radio controls provide a reliable communications link and fill an important need in portable wireless signaling. However, there are some limitations which must be observed.

        For U.S. installations only: The radios  are required to comply with FCC rules and regulations as Part 15 devices. As such, they have limited transmitter power and therefore limited range.

        A receiver cannot respond to more than one transmitted signal  at a time and may be blocked by radio signals that occur on or near their operating frequencies, regardless of code settings.

        Changes or modifications to the device may void FCC compliance.

        Infrequently used radio links should be tested regularly to protect against undetected interference or fault.

        A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale distributor or dealer, and these facts should be communicated to the ultimate users.


This device complies with FCC Rules Part 15 and 1C Canada Rules and Regulations. Operation is subject to the following two conditions: (1) This device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation. - Owned by 1st Garage Door Openers, Inc., an independent family owned and operated business serving the Garage Door and Garage Door Opener Industry since 1981.  Providing excellent customer service and assistance for over 25 years.
