Настройка

Ўстаноўка акумулятара

The School Smart CS-209 calculator uses AG13/LL54 batteries. To install or replace batteries:

  1. Пераканайцеся, што калькулятар выключаны.
  2. Знайдзіце батарэйны адсек на задняй панэлі калькулятара.
  3. Выкарыстоўвайце невялікую адвёртку, каб адкрыць вечка батарэйнага адсека.
  4. Выміце старыя батарэі, калі яны ёсць.
  5. Insert new AG13/LL54 batteries, ensuring correct polarity (+/-).
  6. Замяніце крышку батарэйнага адсека і замацуеце яе шрубай.
