Teeb liab rau kev cim thaum hmo ntuj
Rau cov pej thuam telecom uas siab tshaj 45 meters:
• 1 lossis 2 lub teeb liab ruaj khov qis rau sab saum toj.
Rau cov pej thuam xov tooj cua lossis cov pej thuam sib txuas lus uas siab ntawm 45m thiab 105m:
• 1 lub teeb liab ntsais nruab nrab hom B nyob rau sab saum toj.
• 2 lossis 3 lub teeb liab ruaj khov qis hom B ntawm theem nruab nrab (tsis pub tshaj 52 meters ntawm theem sab saud lossis hauv av) Yog tias lub pej thuam siab dua 105 meters, yuav tsum ntxiv cov teeb liab nruab nrab thiab qis dua lwm yam.
Hauv qab photocell thiab tswj txee xaiv tau (built-in photocell sab hauv lub taub hau flash kuj siv tau)
• Rau cov pej thuam siab 105m txog 150m, 2 txog 4 lub teeb dawb ci ntsa iab nruab nrab hom A ntawm theem nruab nrab.
• Rau cov pej thuam siab tshaj 150 meters yog tias muaj cov kab liab thiab dawb pleev xim, ntxiv cov qib nruab nrab hom A txhua 105 meters siab tshaj plaws (qhov siab tshaj plaws hauv lwm qhov xwm txheej).
