I'm moving to the next level and installing a pair of CW filters was an exciting moment because of its personal challenge. I realized why filters are important when operating a wireless transceiver in an intense RadioSport environment or for chasing DX as well.
Noise, it's about the noise, and reducing adjacent frequency interference increases my comfort inside the cans while decreasing fatigue. I removed the access panel from underneath the TS850S and surveyed my tool requirements before installation.
Also, provided instructions directed me to remove two of the five poles prior to installing the filters, I was nervous for fear of making a mistake. It would require factory repair. The poles are located bottom left to the inside of the photograph.
Lastly, I placed my index finger on each before snipping because I didn't want to leave any loose metal inside the chassis.

Tools |
I used needle noise pliers and a Philips head screw driver for removing mounting screws. My fingers did not work inside the narrow spaces after trying a few times. I needed the pliers to start a few threads before tightening hardware.

CW Filters Installed |
There is not a lot of room to maneuver and I needed to back off several threads on the 400Hz filter (left side) because it pulled to the right. I installed the 250Hz unit with a little coaxing proceeding with tightening of the mounting hardware. I didn't need guerrilla thread grip to ensure mechanical connection.

Access Panel Re-installed |
Lastly, I set filter switches via the access panel on the top of the TS850S then reset microprocessor by holding down A=B button at front, then power up the wireless set. The 500 and 270 indicators illuminated as both filters are now functioning according to their design specifications.
Contest on!P.S. This was the easy step now the TS850S needs to talk with my Acer Aspire 5532 notebook after connecting the LCU3-K CAT cable.
