Damaanad Shuruudaha

Qaadashada Taxanaha ZSR2600 waxaa daboolaya mid DARYEELKA Xaddidan ee YEAR, kaas oo ka bilaabanaya taariikhda bilowga ah ee wax iibsigaaga. Waxaan siinaa macaamiisheeda taageerooyin farsamo oo dhan ah. Haddii damaanadku dhacay, adeegga dayactirka oo keliya ayaa laga qaadayaa qaybo (haddii loo baahdo). Haddii ay dhacdo in cutub loo soo celiyo adeeg, ka hor inta aan lagu soo celin unugga, fadlan lagula tali in:

Calaamadda dammaanadda ee lagu dhajiyay guryaha waa inay ahaataa mid ku jirta xaalad wanaagsan.

Qalab cad oo la akhrin karo ayaa sharxaya nambarka nambarka, nambarka taxanaha ah iyo dhibaatooyinka waa in la soo bandhigaa.

3.Fadlan kuxir cutubka weelkiisa asalka ah. Haddii weelkii asalka ahaa aan la heli karin, fadlan ku xir cutubka ugu yaraan 3 inji oo ah walxo nuugta ah.

Qaybaha la soo celiyey waa inay noqdaan kuwo caymis la siiyay oo caymis ku jira. COD iyo ururinta xamuulka lama aqbali karo.

FIIRO GAAR AH: anaga samee maahan qaado mas'uuliyadda burburka ka dhashay xirxir la'aanta unugyada (unugyada) la soo celiyay.

Xaaladda soosocota kuma daboolan dammaanad qaad:

1.Qeybta ayaa ku fashilantay inay qabato ciladaha howlwadeenada.

Calaamadda dammaanadda ayaa wax laga beddelay, la dhaawacay iyo / ama laga saaray.

3.Dhaawac uu sababay Xoog Majeure.

Qeybtu waxay ahayd mid aan la fasaxin iyo / ama la dayactiray.

5.Dhibaatooyin kale oo ka dhasha cilladaha hawlwadeenada.

Xalka Dhibaatada Guud

1.The iftiinka korontada ka dib markii uu ku xiro korontada

Sababta:

(1) Awood koronto oo aan ku xirnayn malaha

(2) Cilad bixinta korontada

Xalka:  

(1) Hubi xiriirka

(2) Beddel adabtarada awoodda

2.Qalabka iftiinka cas

Sababta:

(1) Fibre galinta -12dBm ama wax soo gal indho la'aan ah

(2) Isku xiraha fiibarka oo dabacsan

(3) Isku xiraha fiber-ka ayaa wasakh ah

Xalka:

(4) Hubi gelinta

(5) Hubi xiriirka

(6) Nadiifi isku xira fiyaha
