2.Dapat ang nasusukat na voltahe sa dalawang crystal oscillator is 0.5 voltage drop sa magkabilang paa or pins ng Crystal Resonator /Oscillator
3.Nasukat ko na voltage reading as in 0.00
binaklas ko at nakita kong basag ang crystal sa loob

4.Warning kapag tinanggal yan mawawalan ng power sa bluetooth section at no display sya...
5.Humanap ako ng kapalit na Crystal Resonator ang hinanap ko yung same value na 24.000 MHz(Mega hertz .
6.Nakakita ako sa ibang unit pero hindi magkaparehas ng appearance
