Digi-Code DC-DT1 310MHz 1 Button Delta 3 Compatible Visor Remote
The Digi-Code DC-DT1 is a replacement one-button visor remote made for Linear Delta 3 310 MHz dip-switch radio systems. This style of remote is commonly found on older garage door openers and gate operators where the receiver does not have a modern learn button. Instead, the code is set manually with 8 small DIP switches inside the transmitter and matched to the switch pattern inside the receiver. That makes the DC-DT1 a good choice when the customer still has a working Linear Delta 3 receiver but the original DT-1 style remote is missing, damaged, intermittent, or no longer reliable. The important fitment point is the radio system, not just the brand name on the operator. A Linear, Raynor, garage, or gate operator may use a different receiver if it was changed in the field, so the receiver frequency and switch style should be verified before ordering. The DC-DT1 is intended for one receiver channel and one door or gate function, such as open/close activation. It should not be used as a safety device, and it will not replace rolling-code transmitters or newer learn-button systems.
Compatible With
This remote may be used with the following compatible radio systems when the receiver frequency, coding style, and programming method match:
- Linear Delta 3 310 MHz dip-switch receiver systems
- Linear DR, DR3A, DR-2, DR-4, DRA, DRA-4, DRM, DRQP, GRD, and GRD-2 receivers when set for Delta 3 310 MHz operation
- Older Linear Delta 3 garage door opener radio controls using 8 DIP switches
- Older gate operators using an external Linear Delta 3 310 MHz receiver
- Select older Raynor openers that used Linear Delta 3 DT-1 style radio controls, including commonly referenced R170/R270, R160/R260, R150/R250, and R130/R230 families when the receiver matches
- Replacement or add-on use where the existing working transmitter is Linear DT-1, DNT00002A, or another compatible Delta 3 310 MHz 8-switch transmitter

Technician Note
Remote compatibility is controlled by the installed receiver. Many older garage door and gate operators have had receivers replaced over the years, so the opener cover or brand name may not tell the whole story. Check the receiver label, frequency, switch style, and a known working transmitter whenever possible.
Before Ordering
- Confirm the existing receiver or old remote model number before ordering.
- Match the frequency, code type, and switch or learn-button style to the installed receiver.
- Do not order by operator brand alone if the receiver may have been changed in the field.
- For multi-door setups, confirm how many channels/buttons are needed.
- Replace weak batteries and inspect the old remote case and switch settings before assuming the opener has failed.
Professional Advisory
This transmitter is for access activation only. It is not a safety device and should not be used to bypass photo eyes, safety edges, entrapment protection, or required operator controls. If the operator moves unpredictably, has damaged wiring, or has missing safety devices, have the system inspected by a qualified gate or garage door technician.
Product Q&A
Will the DC-DT1 work with any Linear opener?
No. It works with Linear Delta 3 310 MHz receiver systems that use 8 DIP switches. Linear MegaCode, Multi-Code, and newer learn-button receivers use different radio formats.
What original remote does the DC-DT1 replace?
It is commonly used in place of the Linear DT-1 / DNT00002A style one-button Delta 3 transmitter when the receiver is a compatible 310 MHz Delta 3 unit.
How is this remote programmed?
Set the 8 DIP switches inside the DC-DT1 to match the switch pattern in the receiver or in a known working compatible remote.
Can this remote operate more than one door or gate?
This is a one-button, one-channel transmitter. For multiple Delta 3 receiver channels, use a compatible multi-button Delta 3 transmitter when the receiver setup supports it.
Why should I check the receiver before ordering?
Older operators are often upgraded with replacement receivers. The operator brand may say Linear, Raynor, or another name, but the remote must match the installed receiver frequency and coding style.
