HP 10bII - Environmental Limits

О: What does an “E” іп a number (for example, 2.51E-13) mean?
A: Exponent of ten (for example, 2.51 х 107"). Refer to “Scientific
Notation” on page 30.
Q: Why do I get a wrong answer or the No Solution message
when using ТУМ?
A: Be sure to enter a value for four of the five TVM values before you
solve for the fifth, even if one of the values is zero. (Don’t forget to store
а zero for (EV) if you completely pay off a loan.) Clearing all the registers
(СОЄлй) before entering your known values accomplishes the same thing.
Check to see that the calculator is in the appropriate payment mode
(Begin or End mode) and that P/YR is set correctly.
Q: How can I change the sign of a number in a list of cash flows?
A: You must replace the cash flow entry. See “Viewing and
Replacing Cash Flows” on page 79.
Q: What does PEND in the display mean?
A: An arithmetic operation is pending (in progress).
Q: What does INPUT in the display mean?
A:The @ key has been pressed (page 28).
О: Why is IRR/YR larger than I expected?
A: This is IRR per year. To see a periodic IRR, divide IRR/YR by P/YR.
Environmental Limits
То maintain product reliability, you should avoid getting the calculator
wet and observe the following temperature and humidity limits:
= Operating temperature: 0° to 40°C (32° to 104?F).
® Storage temperature: —20° to 65°C (4? to 149°F).
m Operating and storage humidity: 90% relative humidity at 40°C
(104°F) maximum.
Noise Declaration. In the operator position under normal operation
(per ISO 7779): LpA < 70dB.
