If you require more de tailed informat ion about calculator ope ration and features, plea se refer to the tr aining materials a vailable at: www.
Basic Features 7 2. Press > repeatedly until English displa ys on the screen . 3. Press I until the de sired langua ge is displayed. The displaye d language is the a ctive setting.
Basic Features 8 The top line of the s creen displa ys operation status, oper ator symbols, annunciators, and abbr eviations of the register s, variables, and menu s. Throughout this man ual, this line i s referred to as the top line . In Figure 1-1 , SIN and RPN on the far righ t are on th e top line.
Basic Features 9 Table 1-1 Mode Menu Settings Setting Display Description FIX= 2 The current number of digits di splayed to the righ t of the decimal point. Default is 2 . Key in the number o f digits you wa nt and press I , or press = until the number of digits you want is di splayed.
Basic Features 10 Table 1-1 Mode Menu Settings Setting Display Description Decimal or Comma The current thou sands separator. Decimal (10 00.00 or 1,000.00); Comma (10 00,00 or 1.0 00,00). Default is decimal. Pressing I cycles through the se options. Chain, Algebraic, or RPN The current oper ation mode.
Basic Features 11 Changing the Operating Mode After viewing the de fault settings, suppose you wan t to change the op erating mode from Chain to RPN. See Table 1- 2.
