         Warning:

 

Some customers may want Linx radio frequency (“RF”) 

products to control machinery or devices remotely, including machinery 
or devices that can cause death, bodily injuries, and/or property 
damage if improperly or inadvertently triggered, particularly in industrial 
settings or other applications implicating life-safety concerns (“Life and 
Property Safety Situations”).  

NO OEM LINX REMOTE CONTROL OR FUNCTION MODULE 
SHOULD EVER BE USED IN LIFE AND PROPERTY SAFETY 
SITUATIONS.

 No OEM Linx Remote Control or Function Module 

should be modified for Life and Property Safety Situations.  Such 
modification cannot provide sufficient safety and will void the product’s 
regulatory certification and warranty.

Customers may use our (non-Function) Modules, Antenna and 
Connectors as part of other systems in Life Safety Situations, but 
only with necessary and industry appropriate redundancies and 
in compliance with applicable safety standards, including without 
limitation, ANSI and NFPA standards.  It is solely the responsibility 
of any Linx customer who uses one or more of these products to 
incorporate appropriate redundancies and safety standards for the Life 
and Property Safety Situation application.

Do not use this or any Linx product to trigger an action directly 
from the data line or RSSI lines without a protocol or encoder/
decoder to validate the data.

 Without validation, any signal from 

another unrelated transmitter in the environment received by the module 
could inadvertently trigger the action.

All RF products are susceptible to RF interference that can prevent 
communication.

 RF products without frequency agility or hopping 

implemented are more subject to interference. This module does not 
have a frequency hopping protocol built in.

Do not use any Linx product over the limits in this data guide.

 

Excessive voltage or extended operation at the maximum voltage could 
cause product failure. Exceeding the reflow temperature profile could 
cause product failure which is not immediately evident.

Do not make any physical or electrical modifications to any Linx 
product.

 This will void the warranty and regulatory and UL certifications 

and may cause product failure which is not immediately evident.
