PRODUCT DESCRIPTION
The DXT-21/EC and DXT-23/EC are battery powered portable
transmitters designed for use with Linear’s DX Format receivers
at the same frequency. 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. Transmitters can send a signal for up to
10 seconds per 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. Refer to the
receiver’s instructions for details on programming.
Each transmitter is powered from two 3-Volt #2032 lithium
batteries with an expected battery life of up to 5 years. The red
test/operate indicator lights during operation and can be viewed
from the front or the top of the unit. The indicator will glow dimly
during operation when the batteries get low. It will stop lighting
altogether during operation when the batteries are below 4.5 volts.
A removable pocket clip and belt clip are provided for each
transmitter. Either can be attached to the back of the transmitter
allowing the unit to be clipped to shirt pocket or slid onto a belt.
The top button on each transmitter can be hidden with the top
button cover supplied with each unit.
DXT-21/EC FEATURES
The DXT-21/EC is a two-button, one-code transmitter. Pressing
either the round button on the transmitter’s front, or the small
button on the transmitter’s top will send the same signal.
DXT-23/EC FEATURES
The DXT-23/EC is a three-button, four-code transmitter. Pressing
either of the transmitter’s front buttons sends codes one and two.
Pressing the small button on the transmitter’s top sends code
three. Pressing both front buttons together sends code four.

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
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.
