Description The Delta-3 DT-4B digital transmitter is a four-channel wireless radio control designed for use with automatic garage/gate operators and access control systems. The transmitter can be used with one 4-channel receiver (DR4), two 2-channel receivers (DR2) or four single-channel receivers (DR,DRQ or DRM). Receivers should be mounted at least 8 feet apart. STEP 1: Locate coding switch. Remove the battery access door located on the back of the transmitter case. Identify the coding switch and note that it has eight positions, with ON and OFF clearly labeled. 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 by the installer 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. The transmitter is powered by a 9-volt battery. It 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 it lights dimly, or not at all when transmitting, the battery needs to be replaced. STEP 2A: Coding for single-channel receivers. Pick any combination of OFF/ON codes, and set them on switch keys 3-8 in the transmitter. Match the same code on switch keys 3-8 in each receiver. Set each receivers switch keys 1 and 2 to select which transmitter button will activate it. Transmitter switch keys 1 & 2 are unused and can be in any position. STEP 2B: Coding for two-channel receivers. Pick any combination of OFF/ON codes, and set them on switch keys 3-8 in the transmitter. Match the same code on switch keys 3-8 in each receiver. Set each receivers switch key 2 to select which transmitter buttons (1 & 2 or 3 & 4) will activate it. Transmitter switch keys 1 & 2 and receiver switch key 1 are unused and can be in any position. STEP 2C: Coding for a four-channel receiver. Pick any combination of OFF/ON codes, and set them on switch keys 3-8 in the transmitter. Match the same code on switch keys 3-8 in each receiver. Transmitter and receiver switch keys 1 & 2 are unused and can be in any position. DT-4B CODING SWITCH CODING SWITCHES IN DR2 RECEIVERS RECEIVER TRIGGERS FROM BUTTONS 1 & 2 MATCH 3-8

Connect the receiver(s) to the operators as described in the receivers 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-4B 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.
