This wireless module install onto the PCB of PEQ15/ LA5 devices to provide the user with wireless activation of the device via the RMT300A1 switch from L3 Insight. This wireless module is NOT compatible with Gen 1 PEQ15s and LA5Bs made in 2006 as this capability was not designed and added to the boards back then. All units that came afterward (chocolate chip era, normal LA5 style molds and new molds and forward) are compatible with this wireless module. 
 
These modules are installed in ALL LA5 devices by default. Only ATPIAL-C and PEQ15 devices dont have this module installed.

If you would like to verify your device is compatible with this module, please send an email with pictures of your device to verify compatibility.
