PRODUCT DESCRIPTION

The DXT-41, DXT-42 are battery powered, portable, miniature transmitters designed for use with Linear’s DX Format receivers. Each transmitter can be used in a limitless number of wireless remote control applications. Pressing a button on the transmitter sends a digitally coded wireless signal to its companion receiver. The digital DX code format features over a million possible codes. The DX transmitters are precoded at the factory to unique codes, so no field coding is required. The two-button transmitter sends variations of its preset code depending on which buttons are pressed. Transmitters can send a signal for up to 10 seconds with each single-button activation.

For versatility, any transmitter code can be programmed into any receiver channel. Receivers must be programmed to the transmitter code before system testing and operation. DX Format digital receivers are programmed by “Learning” the preset factory code from the transmitter. Refer to the receiver’s instructions for details on programming.

Each transmitter is powered from two 3-Volt Type 1620 lithium batteries with an expected battery life of up to 5 years. When the transmitter’s range decreases, or stops functioning, replace the batteries.

A detachable key-ring is provided for each transmitter. Each transmitter button has a positive “click” feel. The right button on the DXT-42 has raised bumps for easy identification.

IMPORTANT !!!

Linear radio controls provide a reliable communications link and fill an important need in portable wireless signalling. 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 modifications to the device may void FCC compliance.

✶ Infrequently used radio links should be tested regularly to protect against
