DESCRIPTION

The Delta-3 DT-3+1 is a hand-held four-channel transmitter with a

three-channel section plus an individual one-channel section. It is

designed so that channel 1 may have a system code independent

of the other three channels. This transmitter operating in

conjunction with four single-channel receivers, or one

multi-channel receiver, can perform a variety of remote switching

tasks. The DT-3+1 has 2 digital encoders (switch A, and switch B).

Coding switch “A” is designed for use with private multiple garage

door openers, activated by push buttons 2, 3, and 4. Coding switch

“B” under the back cover is designed for use with less frequently

changed codes, such as a community access gate that can be

activated by push button 1.

NOTE: The transmitter transmits continuously with the button

pressed. The red indicator lights during transmission to indicate

battery condition. Should it fail to illuminate, it is recommended that

you replace the 9-volt battery.

STEP 1

Locate coding switch.

There are two digital coding switches in the

DT-3+1 transmitter. Code switch “A” is exposed by removing the battery access

cover by inserting your thumbnail or small screwdriver under either of the two slots

at the edge of the case. To access switch “B” remove the battery and remove the

rear half of the case by gently pulling down and back on the battery end of the rear

case. (CAUTION: the white plastic push buttons rest freely in case front and may

fall out if care is not exercised.)

STEP 2

Setting Code Switches.

The coding switches have eight keys numbered

1-8. To set coding switch “A”, select any combination of ON or OFF positions for switch

keys numbered 3-8. Use a paper clip or other pointed object (except a pencil or pen) to

set the keys. To set coding switch “B”, select any combination of ON or OFF

positions for switch keys numbered 1-8.

STEP 3A

Code Setting for Four Single-Channel Receivers.

Set keys 3-8 of

receivers 2, 3, and 4 to match keys 3-8 of switch “A”. Set keys as follows:

Receiver 1 - Set all eight keys to match switch “B”, activates from button 1

Receiver 2 - Set Key 1 and 2 OFF, match keys 3-8, activates from button 2

Receiver 3 - Set Key 1 ON, Key 2 OFF, match keys 3-8, activates from button 3

Receiver 4 - Set Key 1 OFF, Key 2 ON, match keys 3-8, activates from button 4

STEP 3B

Code Setting for Four-Channel Receiver.

Set coding switch keys

3-8 of receiver to match keys 3-8 of coding switch “A” of the DT-3+1. Matching

these keys completes the coding procedure required to activate the first THREE

channels of the receiver. The receiver keys 1 and 2 do not have to be set. Their

functions are preprogrammed to access channels 1-4. Receiver channels are

activated as follows:

Channel 4 of the receiver can be

activated by setting keys 3-8 of

coding switch “B” to match keys 3-8

of coding switch “A”. Set keys 1, and

2 of coding switch “B” to on position.

Channel 4 of receiver can now be

activated by pressing button 1 of the

DT-3+1.

STEP 4

Test the equipment.

Connect the receiver(s) to the operators as

described in the receiverʼs installation instructions. Be sure the door/gate area

is clear. Activate the transmitter and verify that the receiver triggers the operator.

Check that the correct button on the DT-3+1 activates the desired operator.

BATTERY REPLACEMENT

The battery should last 12 to 18 months with normal use. The red

LED on the face of the transmitter will glow when the unit is

activated. When the red LED lights dimly, or not at all when

transmitting, the battery needs to be replaced. Remove the battery

access door to change the battery. Any type of 9-volt battery can

be used.

IMPORTANT !!!

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. 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.
