IF YOU HAVE ANY QUESTION ABOUT THE COMPATIBILITY OF THIS RECEIVER WITH YOUR TRANSMITTER PLEASE ASK!  I AM HAPPY TO HELP!  JUST BECAUSE THIS MAY LOOK LIKE THE RECEIVER YOU CURRENTLY HAVE DOES NOT MEAN IT WILL BE COMPATIBLE WITH YOUR SYSTEM.
THIS IS NOT COMPATIBLE WITH A BOUNDARY PLUS TRANSMITTER OPERATING IN SSP-A MODE.

Invisible Fence MOD:RIG00-11933 800 Series Microlite Receiver 10k Frequency With a New, Sealed Invisible Fence Battery And Used Invisible Fence Brand Collar.  You will receive the exact items pictured.

Compatible with ICT-801, ICT-802, Shields and Shields Plus Indoor and Outdoor Boundary systems that are set to 10K frequency.  To check the frequency of your transmitter system, remove the cover and there will be a light next to either 7K or 10K.  Some ICT-801 models have an additional setting... "7XX-8XX", which allows you to operate the transmitter in either 700 Series or 800 Series mode. If your ICT-801 has this feature, ensure it is set to 8XX. If it is set to 7XX, you will need a 700 Series collar.  It will also work with the Boundary Plus System if you set it to 10k and Outdoor Mode (will not work in SSP-A Mode).
 
This MICROLITE 800 series receiver will NOT work with: ICT-50/50A, ICT-100/100A, ICT-150, ICT-250, ICT-700, ICT-725, ICT-750, Invisible Gate or IFA 12 Indoor Barrier systems (these are 700 series systems).
IF YOU HAVE ANY QUESTION ABOUT YOUR TRANSMITTER BEING COMPATIBLE WITH THIS RECEIVER, PLEASE ASK.  IF YOU WISH TO SEND ME A PHOTO OF YOUR TRANSMITTER WITH THE INTERIOR LIGHTS ON, I WILL BE HAPPY TO IDENTIFY WHAT YOU NEED.
