PRODUCT DESCRIPTION

The DXS-21, DXS-23 and DXS-25 are supervised, digitally coded
radio transmitters designed for use with Linear’s DX and DXS Format
receivers. Pressing a button on the transmitter sends a digitally coded
wireless signal to its companion receiver.

To send a complete signal,

press the transmitter button for a minimum of 2 seconds.

The digital DXS code format features over a million possible codes. The
DXS transmitters are precoded at the factory to unique codes, so no field
coding is required. The multi-button transmitters send variations of their
preset codes depending on which buttons are pressed. Transmitters can
send a signal for up to 10 seconds per activation.

The transmitters are supervised for low battery and send hourly status
reports. Some receivers are able to use these signals, others are not.

Receivers must be programmed to the transmitter code before system
testing and operation. Refer to the receiver’s instructions for details
on operation and programming.

Each transmitter is powered by two self-contained type 2032 3-volt
lithium batteries (included). When the batteries voltage gets low, a low
battery report is sent with any alarm or status report to notify the
receiver. The red LED will blink when the transmitter is activated with
low batteries.

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.

TRANSMITTER CONFIGURATIONS

DXS-21

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.

DXS-25

The DXS-25 is a five-button, eight-code transmitter. Pressing any of
the transmitter’s front buttons sends codes one through four. Holding
down the small button on the transmitter’s top together with pushing
with any of the front buttons sends codes five through eight.

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 Par t 15 devices. As s uch, 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.
