Calculationofthethrowdistancefromthescreensize
NP11FLlensthrowdistance(m)=H×0.8:0.7m(min.)to2.6m(max.)
NP30ZLlensthrowdistance(m)=H×0.8toH×1.0:1.0m(min.)to11.3m(max.)
NP12ZLlensthrowdistance(m)=H×1.2toH×1.5:0.7m(min.)to16.5m(max.)
NP13ZLlensthrowdistance(m)=H×1.5toH×3.0:1.2m(min.)to31.9m(max.)
NP14ZLlensthrowdistance(m)=H×2.9toH×4.7:3.7m(min.)to50.9m(max.)
NP15ZLlensthrowdistance(m)=H×4.6toH×7.1:5.9m(min.)to76.4m(max.)

Accordingtothe“ScreenSize(forreference)”table(→ page 256),H(screenwidth)=323.1cm.
Thethrowdistanceis323.1cm×1.5to323.1cm×3.0=484.7cmto969.3cm(becauseofthezoomlens).
