Mighty Mule 362-D FM135 Remote Control Single Button Transmitter
The RB741, also commonly searched as FM135, is a single-button 318 MHz remote transmitter used with compatible Mighty Mule, GTO, and Linear PRO gate opener radio systems. This remote style is commonly associated with 9 DIP switch coding, where the switch pattern in the transmitter must match the receiver or control-board radio settings. On an FM362-D parts page, this remote is typically ordered when the original hand transmitter is lost, damaged, worn out, or when an additional user needs basic one-gate access. Remote compatibility depends on the receiver technology, not only the gate opener model name. Older DIP-switch receivers, newer radio boards, dual-channel setups, and accessory receivers may require different transmitters. The RB741/FM135 family should be matched by frequency, coding method, button count, and the existing receiver setup.

Technician Note
Remote compatibility follows the receiver. Always compare the existing transmitter, receiver label, frequency, and DIP switch layout before replacing or adding remotes.
Before Ordering Checklist
- Confirm the existing remote is RB741, FM135, or a matching 318 MHz 9 DIP switch transmitter.
- Confirm the gate receiver uses DIP switches and not a different security format.
- Choose RB741/FM135 for single-button use only.
- Use RB742/FM134 style references when two-button control is required.
- Replace weak remote batteries before assuming the transmitter has failed.
Important Ordering Warnings
- RB741/FM135 is commonly a single-button remote family; do not confuse it with RB742/FM134 two-button transmitters.
- Aftermarket receiver changes can alter remote compatibility even when the gate opener model is the same.
Professional Advisory
Do not change receiver wiring or bypass access control equipment to make a remote work. If the receiver type is unknown, have a gate technician identify it before ordering.
Product Questions and Answers
Is RB741 the same as FM135?
RB741 and FM135 are commonly used as related search references for the single-button Mighty Mule/GTO style 318 MHz DIP-switch transmitter family.
Will this remote work with every Mighty Mule opener?
No. It must match the receiver frequency and coding method. Many Mighty Mule and GTO systems use 318 MHz DIP-switch remotes, but some newer or modified systems may use a different receiver.
How is the RB741 programmed?
This style is commonly matched by setting the 9 DIP switches to the same pattern used by the receiver or existing compatible remote.
Is RB741 a two-button remote?
No. RB741/FM135 is commonly treated as a single-button transmitter family. For two-button use, check RB742/FM134 style references instead.
What should I check before ordering an extra remote?
Check the existing remote part number, receiver frequency, DIP-switch layout, and whether your system needs one-button or two-button control.
