Utumiki ndi Kukonza

Ngati makina anu asokonekera, muyenera kuyesa kukonza kapena kulekanitsa vutolo musanaganize kuti zidazo zikufunika kukonzedwa. Onetsetsani kuti mwatsatira njira yokhazikitsira ndi malangizo ogwiritsira ntchito. Chongani zingwe interconnecting ndiyeno kudutsa Troubleshooting gawo mu bukhuli.
Tikukulimbikitsani kuti musayese kukonza zidazo nokha ndipo musakhale ndi malo okonzerako komweko kuyesa china chilichonse kupatula kukonza kosavuta. Ngati kukonza kuli kovuta kwambiri kuposa waya wosweka kapena kugwirizana kotayirira, tumizani unit ku fakitale kuti ikonzedwe ndi ntchito. Osayesa kusintha zowongolera zilizonse mkati mwa mayunitsi. Zikakhazikitsidwa pafakitale, zowongolera zosiyanasiyana ndi zowongolera sizimayenda ndi zaka kapena kugwedezeka ndipo sizifunikira kusinthidwanso. Palibe zosintha mkati zomwe zingapangitse kuti gawo losagwira ntchito liyambe kugwira ntchito.
Dipatimenti ya Utumiki ya LECTROSONICS ili ndi zida ndi antchito kuti akonze zida zanu mwachangu. Mu chitsimikizo, kukonzanso kumapangidwa popanda malipiro malinga ndi mfundo za chitsimikizo. Kukonza kunja kwa chitsimikizo kumaperekedwa pamtengo wocheperako kuphatikiza magawo ndi kutumiza. Popeza zimatengera pafupifupi nthawi yochuluka ndi khama kuti mudziwe chomwe chili cholakwika monga momwe zimakhalira kukonza, pali mtengo wa mawu enieniwo. Tidzakhala okondwa kutchula mtengo womwe ungalipire pafoni kuti ukonze zomwe sizinatsimikizike.

Magawo Obwezera Kuti Akonze

OSATI kubweza zida kufakitale kuti zikonze popanda kutilankhula ndi imelo kapena foni. Ife tikusowa
kuti mudziwe mtundu wa vuto, nambala yachitsanzo, ndi nambala ya serial ya zida. Tikufunanso nambala yafoni komwe mungapeze 8 AM mpaka 4 PM (US Mountain Standard Time).

Mukalandira pempho lanu, tidzakupatsani nambala yovomerezeka yobwezera (RA). Nambala iyi ikuthandizani kukonza mwachangu kudzera m'madipatimenti athu olandila ndi kukonza. Nambala yovomerezeka yobwezera iyenera kuwonetsedwa bwino kunja kwa chotengera chotumizira.
Nyamulani zida mosamala ndikutumiza kwa ife, mtengo wotumizira ulipiretu. Ngati ndi kotheka, titha kukupatsirani zida zoyenera zonyamula. UPS nthawi zambiri ndiyo njira yabwino yotumizira mayunitsi. Magawo olemera ayenera kukhala "mabokosi awiri" kuti ayende bwino.
Tikukulimbikitsaninso kuti mutsimikizire zidazo chifukwa sitingakhale ndi mlandu pakutayika kapena kuwonongeka kwa zida zomwe mumatumiza. Zachidziwikire, timatsimikizira zida tikamatumiza kwa inu.
