   * Remove the head unit by prying gently along the bottom edge between the seal and head unit plastic (page 34 Fig. 2.1 - {{:radios:mm8100-02-00-812_tm8100_mobile_radio_service_manual.pdf | TM8100 service manual}})
-  * Remove the 3 screws from the PCB (page 38 Fig. 2.4 part 7 - {{:radios:mm8100-02-00-812_tm8100_mobile_radio_service_manual.pdf | TM8100 service manual}}), pull off the volume knob (this will separate easily with a firm pull, and will leave a metal retention spacer either on the spoke or in the knob. Don't lose this!) and release the three clips on the PCB retainer in the head unit (page 134 Fig. 6.4 - {{:radios:mm8100-02-00-812_tm8100_mobile_radio_service_manual.pdf | TM8100 service manual}}), removing the PCB and speaker from the assembly. Take care to not disturb the exposed LCD as this will mis-aslign the zebra contact strips.

   * Remove the button membrane which may contain lots of dirt buildup. Remove the 4 plastic light pipes from the membrane, wipe them clean and set them safely aside. They are keyed in two directions, both which side of the membrane they sit on (square vs round) and orientation (teardrop shape) so you cannot re-insert them wrong without it fighting you.

   * Use warm, soapy water and a disposable cloth and toothbrush to gently clean the button membrane. Take care to not rub off the symbols, and do not scrub the black pads on the back as these are conductive contacts. This is safe to submerge. Rinse and ensure dried (don't use the hairdryer here, but pat and shake dry and leave to the side for a while). Make sure you did not miss any water in the light pipe holes or between the buttons. You can replace the light pipes once dry.
-  * Re-insert the membrane, click back in the PCB (make sure the speaker alignment slot is correctly positioned) and make sure you put the screws back in. Failure to do so will result in the LCD being non or partially operational, as it relies on the pressure provided by the screws.

   * Ensure the o-ring is seated correctly and will not be pinched, then replace and screw down the top plate.
+=== Mic ===
+  * The mic is extremely simple and completely passive electronically, thus easy to disassemble. Remove the 4 rear screws and pry off the back cover.
+  * Unscrew the PCB and lift it gently, unplugging it from the cable.
+  * Very gently pull the mic out of the front plastic and set the PCB aside.
+  * Lift and remove the PTT plastic button and metal spring. Clean the PTT plastic button with an anti-bac.
+  * Remove and wipe down the rubber seal/button passthrough piece.
+  * Wipe the outer casings and run an anti-bac along the coiled cable. Make sure to clean the screw holes with an anti-bac and small screwdriver.
+  * The grille on the front of the radio is 99% for show with only a small hole for the mic itself. You can scrub this gently using a toothbrush and some kind of spray, though make sure you did remove the mic and separate away the PCB in the previous step. An anti-bac probably won't go deep enough. I used 99.9% IPA successfully but this is not advised as it can be harsh, but is very effective at removing grime.
+  * Reattach the rubber seal, place back in the spring and PTT plastic button, reinstall the PCB (there are wire routing channels for the mic wires), and screw the mic together.
