Marka laga hadlayo mabda'a dayactirka goleyaasha wareegga ee PCB, mashiinka iibiyaha otomatiga ah ayaa bixiya ku habboonaanta booqashada wareejinta PCB, laakiin dhibaatooyinku badanaa waxay ku dhacaan geedi socodka wax soo saarka ee looxyada wareejinta ee PCB, taas oo saameyn ku yeelan doonta tayada iibka. Si loo wanaajiyo saameynta tijaabada, qaar ka mid ah farsamada waa in lagu sameeyaa guddiga hagaajinta ka hor tijaabada khadka tooska ah ee guddiga 'PCB' oo lagu yareeyo saameynta faragelinta kaladuwan ee geedi socodka tijaabada. Tallaabooyinka qaaska ah waa sida soo socota:
. Diyaarinta baaritaanka ka hor

Wareegtada gaagaaban ee oscillator-ka (feejignaanta leh ee 'crystal ospillator' ee afarta-pin ah si aad u ogaato in labada biintu ay yihiin kuwa kale ee ku-meel-gaarka ah oo ay tahay in la wareejiyo korantada oo aan gabi ahaanba ahayn awoodda awooda badan ee awooda loo yaqaan 'Pictorolytic' ee awooda leh waa in loo sameeyaa si ay u furnaadaan. Sababtoo ah khidmadda iyo sii-daynta xasaaraha awooda-weyn ayaa waliba sababi doona faragelin.

2. U adeegso habka ka saarida si aad u tijaabiso guddiga PCB ee aaladda

Inta lagu gudajiro imtixaanka internetka ama tijaabada isbarbardhiga ee aaladda, fadlan si toos ah u xaqiiji natiijada tijaabada oo diiwaan geli aaladda ka gudbisay imtixaanka (ama caadi ahaan). Haddii tijaabadu ku guuldareysato (ama u dulqaadasho), mar labaad waa la baari karaa. Haddii ay wali ku guuldareysato, waxaad sidoo kale ku xaqiijin kartaa natiijooyinka baaritaanka marka hore. Tani waxay sii socotaa ilaa aaladda ku taal guddiga la tijaabiyo (ama marka la barbar dhigo). Kadib la macaamil aaladahaas oo ku dhaca imtixaanka (ama dulqaadasho).

Qaar ka mid ah aaladaha wax lagu baaro ayaa sidoo kale bixiya hab aan rasmi ahayn laakiin wax ku ool ah oo wax ku ool ah oo loogu talagalay aaladda aan ku gudbin karin imtixaanka khadka tooska ah ee shaqada Haddii pin-ka korantada ee aaladda la jaro PIN-ka PIN, aaladda waxaa laga goyn doonaa nidaamka sahayda korantada ee guddiga wareega.
Waqtigaan, ku samee tijaabada internetka ee internetka ee aaladda; Maaddaama aaladaha kale ee PCB aysan awood u lahayn inay ka shaqeeyaan si loo baabi'iyo saameynta faragelinta, saameynta dhabta ah ee tijaabada waqtigan waxay u dhigmi doontaa "imtixaanka 'Quasi-offline'. Heerka saxda ah wuxuu noqon doonaa mid aad u sarreeya. Horumarin weyn.
