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.

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.
