Linear Multi-Code 4140 4-Channel Visor Remote – 300 MHz Fixed-Code Transmitter

The Linear Multi-Code 4140 is a 4-channel wireless visor transmitter designed for compatible 300 MHz Multi-Code garage door, gate, and access-control receivers.

Four independent push buttons allow one transmitter to control up to four compatible receiver channels or access points, making it ideal for facilities, commercial properties, gates, or users who need to operate multiple doors from a single remote.

The 4140 uses traditional Multi-Code fixed-code DIP-switch programming and is powered by a standard 9V battery.

Four-Channel Operation

Each of the four buttons can activate a different compatible receiver or receiver channel.

• Garage Door 1

• Garage Door 2

• Entry Gate

• Secondary Gate or Door

The exact function of each button depends on how the compatible receivers are programmed.

Compatible Systems

The 4140 is designed for compatible 300 MHz Multi-Code fixed-code receivers, including:

• Linear / Multi-Code 300 MHz receivers

• Multi-Code 109950 receivers

• Multi-Code 302850 dual-channel receivers

• Compatible legacy Multi-Code garage door receivers

• Compatible fixed-code gate receiver systems

It may also be used in systems where other compatible 300 MHz Multi-Code transmitters are already operating.

Programming

The Model 4140 contains two internal code-switch banks, identified as Side A and Side B.

The code switches are set to match the compatible receiver configuration. Different button/channel combinations use the two switch banks to allow operation of up to four receiver channels.

For replacement installations, compare the existing working transmitter and receiver programming before changing switch settings.

Important Compatibility Note

This remote is not universal.

Before ordering, verify:

• Frequency: 300 MHz

• Radio Format: Multi-Code Fixed Code

• Receiver model

• DIP-switch configuration

• Number of channels required

The 4140 is not intended for:

• 310 MHz Stanley-compatible systems

• LiftMaster Security+

• LiftMaster Security+ 2.0

• Genie Intellicode

• MegaCode

• Other rolling-code systems

Do not order based only on the appearance of the existing transmitter.

Raised Button Identification

The four buttons include raised tactile markings to help users distinguish between channels without needing to look closely at the transmitter.

This can be especially useful when operating multiple doors or gates from the same vehicle.

Package Contents

Includes:

• 1 Linear Multi-Code 4140 4-Channel Transmitter

• Visor clip

• 9V battery

Receivers, antennas, operators, and other radio-control accessories are sold separately.
