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