RXM-418-KH3

KH3 Series Transmitter Module

Unspecified 

! Warning: Linx radio frequency ("RF") products may be

used 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. No Linx

Technologies product is intended for use in any application without

redundancies where the safety of life or property is at risk.

The customers and users of devices and machinery controlled with

RF products must understand and must use all appropriate safety

procedures in connection with the devices, including without limitation,

using appropriate safety procedures to prevent inadvertent triggering by

the user of the device and using appropriate security codes to prevent

triggering of the remote controlled machine or device by users of other

remote controllers.

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.
