Your Hewlett-Packard Calculator
Your calculator is another example of the award-winning design,
superior quality, and attention to detail in engineering and construction
that have marked Hewlett-Packard electronic instruments for more than
30 years. Each Hewlett-Packard calculatoris precision crafted by people
who are dedicated to giving you the best possible product at any price.
AC Line Operation
Your calculator contains a rechargeable battery pack consisting of
nickel-cadmium batteries. When you receive your calculator, the battery
pack inside may be discharged, but you can operate the calculator
immediately by using the ac adapter/recharger.
Note: Do not attempt to operate the calculator from an ac
line with the battery pack removed.
The procedure for using the ac adapter/recharger is as follows:
1.
You need not turn the calculator off.
2.
Insert the ac adapter/recharger plug into the connector on the top
of the calculator, with the snap release tab on the plug facing
toward the right side of the calculator.
3.
Insert the power plug into a live ac power outlet.
Note: It is normal for the ac adapter/recharger (and the
battery pack) to be warm to the touch when plugged into an
ac outlet.
