DESCRIPTION
Linear’s GT series of digital transmitters are wireless
radio controls designed for use with Genie Pro®
INTELLICODE™, Overhead Door® CodeDodger™, and
Linear® Model AM-RGR access control receivers. The
rolling-code GT radio format provides additional security
by changing the transmitter’s code with each use.
The GT-30 is a three-button transmitter that sends a
unique code for each button. Typically, one button is used
to operate a community access gate, another button can
activate the individual’s garage door, and a third button
can control an additional door or other device.
The transmitter is powered by two Type 2016 “coin cell”
batteries. A red indicator lights when the transmitter is
activated. A removable spring steel visor clip is supplied
attached to the back of the transmitter.
☞ NOTE: INTELLICODE™, CodeDodger™, Genie Pro®, and Overhead
Door® are registered trademarks of Overhead Door Corporation.
PROGRAM TRANSMITTER INTO RECEIVER
For INTELLICODE™ and CodeDodger™ systems, refer
to the instructions provided with the receiver to set it to a
“learning” mode. Activate the desired transmitter button
to program that button into the receiver
Linear’s Model AM-RGR receivers detect the signal from
the transmitter and pass its digital code to the AM/II
access controller.
GT-30 transmitters are manufactured and sold “Block
Coded” from the factory. Each block of transmitters is
labeled with the starting and ending block code number,
along with a facility code number. Refer to the AM/II
instructions for details on how to program the block and
facility code numbers into the controller.

IMPORTANT !!!
Linear radio controls provide a reliable communications link and fi ll an important need in portable
wireless signaling. However, there are some limitations which must be observed.
• For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as Part 15
devices. As such, they have limited transmitter power and therefore limited range.
• A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio
signals that occur on or near their operating frequencies, regardless of code settings.
• Changes or modifi cations to the device may void FCC compliance.
• Infrequently used radio links should be tested regularly to protect against undetected interference or fault.
• A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale distributor
or dealer, and these facts should be communicated to the ultimate users.
• This device complies with FCC Part 15. Operation is subject to the following two conditions: (1) This device
may not cause harmful interference and (2) this device must accept any interference received, including
interference that may cause undesired operation.
