PRODUCT DESCRIPTION
The Model DXS-LRC is a battery powered, miniature, water-resistant*, supervised 
transmitter designed for use in emergency applications with Linear’s DX and DXS 
format receivers. The transmitter is “convertible” for installation into either the 
wristband OR pendant mounting accessory. WARNING! Do Not attempt to  
remove a transmitter from its mounting accessory or damage may result.
The DXS-LRC sends a signal when its activation button is pressed. The signal 
indicator on the transmitter lights green when the unit is activated. To insure 
sending a complete signal, press the transmitter button for a minimum of two 
seconds. The transmitter can send a signal for up to 30 seconds per activation. The 
DXS-LRC transmitter is factory set to a unique code, so no fi eld coding is required. 
Receivers must be programmed to the transmitter’s code before system testing and 
operation. Refer to the receiver’s instructions for details on programming.
If status transmissions are enabled, the transmitter will send a status signal every 
two hours. Some receivers are able to monitor status signals, others are not.
Every two hours the transmitter tests for a low battery. This test takes place even 
if status transmissions have not been enabled. If the battery tests low, a low 
battery signal is sent. If the transmitter is activated with a low battery, the signal 
indicator will light red.
The transmitter is sealed to provide water-resistance. The unit’s battery is not 
replaceable. The transmitter should be discarded at the end of its battery life.
* NOTE: Water resistance not tested by UL

Linear radio controls provide a reliable communications link and fi ll an important need in por table 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 and Canada Rules and Regulations. 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.
