2100 microphone - GSM-Forum

Tbaba · 01-22-2006, 08:52

have a 2100. microphone isn't working at all. I changed the mic and also rehot the CCONT, but still no solution. The handsfree is working fine. Can i connect the internal mic to the handsfree connections on the PCB? Can anyone show me ?

@bond95
thanks so much for the info, i've just done this but now the speaker doesn't work. It was working before. or must i use the speaker inside the handsfree? pls reply, thanks

(PS i did remove the 2 resistors for the speakers and also the 2 resistors and condenser on the mic way. the mic is now working but the speaker isn't)

Thanks @lab_gsm

Initially the ear pice was fine but the mic wasnt good and the handsfree (mic and earpiece) were working.
tried the above 8210 handfree conversion posted above by removing the 2 resistors in the speker path (they're actually inductors i think) and the 2 resistors and 1 capacitor in the mic path( they're on the same side of the PCB for the 2100). After this (the hansdfree conversion) the mic worked but then the speaker didnt work anymore. after all attempts i put all the compoenents back removed all the jumper wires and also reheated the COBBA IC (the phone was back to normal) and surprisingly the the mic was still working, but the speker still didn't work and the handsfree was still working too! I just dnt really understand, any ideas on getting the speaker to work now? thanks
