ご教示頂けましたら幸いです

Hi guys!

Another thing I did is releasing the battery and power on.

Other function is OK except hearing the callers voices.

Off course I do not use the earphone jack.
No dust in Microphone


I'm Taichi

This is from Japan.

My problem is that I cannot hear the callers voices using a PANTEC cellphone PT002 with me.

Button I push for more than 1 second is the lowest left one: * mummer

I'm in trouble using a PANTEC cellphone PT002 NOW as it does not allow me to hear any outside callers's voices from it even though I set it on and off manner mode many times, only choosing either A) or B)below

A) Basic manner on buzzing

from A) to B): keep pressuring the lowest left one * mummer for more than 1 second
