2 Entry with the number entry and time keys ɾAfter entering numbers, enter the time digit ([࣌(HOUR)],[෼ (MINUTE)] or [ඵ (SECOND)]). ɹThis method is useful for entering time having blank digits. Ex. 1) 2 hours 15 minutes and 10 seconds ɹɹ


[2] [࣌ (HOUR)] [1] [5] [෼ (MINUTE)] [1] [0] [ඵ (SECOND)] ˠIn this case, the entry can be made more easily ˢ ɹwith the previous method using the number entry ɹEntry of [ඵ (SECOND)] can be eliminated.ɹɹɹkɹeyɹsɹonɹlyɹ . ɹɹ
Ex. 2) 15 minutes and 2 seconds (When [ඵ (SECOND)] is entered, " ˅" will be displayed.) ɹɹ [1] [5] [෼ (MINUTE)] [2] [ඵ (SECOND)]ˠStart entering from the digits having numbers. ˢ
Ex. 3) 10 hours and 8 seconds Entry of [ඵ (SECOND)] can be eliminated. ɹɹ

[1] [0] [࣌ (HOUR)] [0] [8] [ඵ (SECOND)]ˠIt is not necessary to enter [෼ (MINUTE)]. ˢ
Notes: Entry of [ඵ (SECOND)] can be eliminated. ɹɾIf a wrong number has been entered, press the clear/clear entry key and enter the correct one. ɹɾIf more than three numbers are entered in succession without pressing the time keys, the time keys will not work, ɹ

and the entry of the remaining digits should be made according to the method using the number entry keys only. ɹɾIf a number greater than 60 is entered for the minute or second digits, one hour or minute is added when [ʴ], [ʵ] ɹ

or [ʹ] is entered. (In this case, " ˅" mark will be displayed.) ɹɾWhen a calculation result exceeds 99 hours 59 minutes and 59 seconds, the error mark "Error" is displayed. ɹ To clear the error mark, press the clear/clear entry key. The digits are reset to "0". Addition 1 Standard calculation ɾEnter a time, [ʴ], another time and [ʹ]. ɹEx.)

(3 minutes and 25 seconds)ʴ(2 minutes and 1 second): ɹɹɹ[3] [2] [5] [ʴ] [3] [0] [1] ɹɹɹɹTo correct "3" to "2" : ɹɹɹ[C/CE] [2] [0] [1] [ʹ] Note: If no arithmetic operation key is pressed after a wrong number has been entered, it can be corrected easily using the clear/clear entry key. If an arithmetic operation key is pressed after a wrong entry, however, the entry cannot be undone. In that case, press the clear/clear entry key to cancel the calculation, and then, reenter the times from the beginning. In the case of the example above, enter the times from "3 minutes and 25 seconds" again.ɹ 2 If a wrong arithmetic operation key is pressed: ɹ Press the correct one immediately after the wrong key is pressed. ɹEx.) (3 minutes and 25 seconds)ʴ(2 minutes and 1 second): ɹɹɹ[3] [2] [5 If you noticed the mistake at this point, press the proper key immediately ɹɹɹɹafter the wrong one 2] [0] [ʹ] How to use the calculation result in other modesɹ (Timer and stopwatch modes) ɾThe calculation result obtained in the time calculation mode is automatically stored in memory and ɹcan be recalled and used as the strarting time in the timer and stopwatch functions. ɹ1 After a calculation is completed, change the mode to the timer or stopwatch before a new calculaɹtion is made. ɹ(Turn the mode selector to change the mode.) ɹ2 If the timer or stopwatch is counting, press the buttons to stop and reset it. ɹThen, press the recall key. The calculation result will be recalled and displayed. ɹ3 Press button ɹ B to start the timer or stopwatch. ɹ (For details, refer to "˙ HOW TO USE THE TIMER" and "˙ HOW TO USE THE STOPWATCH".) Notes: ɹɾIf the calculation by pressing arithmetic operation keys, the time entered in the time calculation ɹɹmode cannot be stored and recalled in the timer or stopwatch modes. In that case, the calculation ɹɹresult obtained previously will be displayed by pressing the recall key. Check the displayed time ɹɹbefore starting the timer or stopwatch. ɹɾWhen calculations are made successively, the calculation result stored in memory is renewed ɹɹeach time a calculation is made. ɹɾIf the error mark "Error" is displayed after a calculation, the memory is cleared completely, and ɹɹthe previous calculation result will also be erased from memory. Therefore, "0" will be displayed ɹɹwhen the recall key is pressed. ɾThe calculation result stored in memory will be retained unless a new calculation is made or unless the error mark is displayed after a calculation. ɾThe calculation result in memory cannot be displayed in the time calculation mode. ɾThe calculation result in memory cannot be erased by pressing the clear/clear entry key. Remarks on the calculation ɾIf the calculation result is more than 99 hours 59 minutes and 59 seconds or less than-99 hours 59 minutes and 59 seconds, the error mark "Error" will be displayed and no digits will be shown if the number entry key are pressed. In that case, press the clear/clear entry key to reset the digits to "0". ɾIf the error mark is displayed, the calculation result retained in memory will be erased and "0" will be displayed by pressing the recall key in the timer or stopwatch mode. ɾIf the mode selector is turned to change the mode from the time calculation mode to another during or after a calculation, entered time or calculation result shown on the display will be erased and "0" will be displayed when the mode is returned to the time calculation.
