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 calculator is 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 the ac
line with the battery pack removed.
The procedure for using the ac adapter/recharger is as follows:
1.
2.
You need not turn the calculator off.
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.
Insert the power plug into a live ac power outlet.
Note: It is normal for the ac adapter/recharger to be warm
to the touch when it is plugged into an ac outlet.
CAUTION
The use of a charger other than the HP recharger supplied
with the calculator may result in damage to your calculator.
For the Continuous Memory model use only the "B" suffix
version ac adapter/recharger shipped with your calculator
(see product number on recharger). Earlier "A" suffix version
rechargers will not damage your calculator, but may clear
continuous memory when plugged in.
