11. Qaylo hoose, wax arbushaad ama raaxo la'aan ah inta lagu jiro tijaabooyinka kooxda.
Kormeeraha tijaabada ah ee Pohl.
1. Koontarool tijaabo oo gaar ah ayaa loo isticmaalaa si loo ururiyo loona muujiyo xogta; bandhig LCD oo dhibco-matrix ah oo weyn ayaa la isticmaalaa, oo leh menus si uu u hago tijaabada, qoraalo dhiirigelinaya (Buuga tilmaamaha elektaroonigga ah), iyo soo bandhigida iyo dib u hubinta xogta tijaabada ah.
2. Interface kontoroolka u go'an oo loogu talagalay strobes.
